Hello,

I just installed the 3.2.2 version from R and want now to install packages that I am using in my script (among them tKWidgets). However when entering :

> source("https://bioconductor.org/biocLite.R")

I get the following error message :

Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) :
InternetOpenUrl failed: 'An error occurred in the secure channel support'

Could you help me to fix it ?

Thanks,

Michel

PS the command: source("http://bioconductor.org/biocLite.R") is working when entered from my old 3.0.2 version

Does http:// work on your new R version?

Since you're on Windows XP, you may even run into issues with SSL certificate validation. My understanding is that Windows controls all of this through "Internet Options" in Internet Explorer. To confirm that communication to bioconductor resources works, you could open Internet Explorer and enter "https://bioconductor.org/" in the address bar. Hopefully this works. If not, let us know the outcome. Alternatively, you might try this :

Click Tools and select Internet Options
Click the Security
Consider lowering the "Security level" (this is be dangerous as it'll affect other Internet resources), or you can try adding Bioconductor.org to the list of "Trusted Sites"

Try using http instead of https (you note that http works for R-3.0.2, whereas https doesn't work for R-3.2.2, so you are doing different things with the two different R versions).

Thank you for your responses. I have tried the following :

1- From R version 3.0.2 (2013-09-25), still installed on my PC

the command "> source("http://bioconductor.org/biocLite.R")" is working

but the command "> source("https://bioconductor.org/biocLite.R")" is not working issuing in the following error message:

Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) : unsupported URL scheme

2- From Firefox

Entering : http://bioconductor.org/packages/3.1/bioc/src/contrib/PACKAGES

give me access to the list of package:

Package: a4
Version: 1.16.0
Depends: a4Base, a4Preproc, a4Classif, a4Core, a4Reporting
Suggests: MLP, nlcv, ALL, Cairo
License: GPL-3
MD5sum: 1bd22944d9e6d7bb2f6c742dcf7e340f
NeedsCompilation: no

Package: a4Base
Version: 1.16.0
Depends: methods, graphics, grid, Biobase, AnnotationDbi, annaffy, mpm,

Enhances: gridSVG, JavaGD
License: GPL-3
MD5sum: 0be52bafda21bc84cb17c27376a0b61a

etc....

3 - From the newly installed R version:

R version 3.2.2 (2015-08-14) -- "Fire Safety"
Copyright (C) 2015 The R Foundation for Statistical Computing
Platform: i386-w64-mingw32/i386 (32-bit)

neither > source("http://bioconductor.org/biocLite.R")

nor > source("https://bioconductor.org/biocLite.R")

are working with different error message.Respectively, for the http command
> source("http://bioconductor.org/biocLite.R")
Warning: unable to access index for repository https://bioconductor.org/packages/3.2/bioc/src/contrib
Warning: unable to access index for repository https://bioconductor.org/packages/3.2/bioc/bin/windows/contrib/3.2

and for the https

> source("https://bioconductor.org/biocLite.R")
Error in file(filename, "r", encoding = encoding) :
cannot open the connection
In addition: Warning message:
In file(filename, "r", encoding = encoding) :
InternetOpenUrl failed: 'An error occurred in the secure channel support'

From the fact that I could get the list of packages from firefox, I am encline to think that the problems are not coming from Windows or some configuration but rather from some thing getting wrong with installation of R 3.2.

Best wishes,

Michel

Very curiously I tried to acces BioC through the menu "Package", command "Select repositories". In the proposed list I selected "BioC software". And It worked !

the called function was : setRepositories()
Then I had acces to the list of packages, from which I was able to select and install the different packages that I needed to run my application (neurone activity analysis).

My current problems are solved but still, I am interested in knowing why it did not worked the regular way ! I suspect something in the format of the http command was badly interpreted.

Best regards,

Michel

R 3.2.2 is the first version of R to support https, so attempts to use 3.0.2 with https:// for installing packages is not relevant; let's leave it out of any further discussion.

Your use of firefox did not use https://, so we do not know the status of native https:// support on your system. It would be interesting to discover this.

After using Rstudio's menu command, options("repos") likely returns an http:// protocol, so that you are using http://. The same effect could have been achieved using options(useHTTPS=FALSE) or options(BioC_mirror="http://bioconductor.org").

BiocInstaller tries to guess at https:// support. It would be interesting to know what BiocInstaller:::.protocol() returns on your system. If it returns "https" then it would be interesting to know what file("https://bioconductor.org") returns, and if that succeeds whether the following output is observed

> length(readLines(file("https://bioconductor.org")))

Hi Martin,

New trials and responses hereafter:

1- FIREFOX

https://bioconductor.org/packages/3.1/bioc/src/contrib/PACKAGES is working well with FIREFOX

2- I am not using R studio, but the standard Rgui interface window with a few menus (File Edit, Misc Packages, ...) on the upper bar of the window. This is what I get after choosing bioconductor as repository: and entering the options() function:

> setRepositories()
> options("repos")
$repos
BioCsoft
"http://bioconductor.org/packages/3.1/bioc"

3 - BiocInstaller is failing :
> BiocInstaller:::.protocol()
Error in loadNamespace(name) : there is no package called ‘BiocInstaller’
>

But I think Biocinstaller is not installed on my machine.

4-

> file("https://bioconductor.org")
               description                      class
"https://bioconductor.org"              "url-wininet"
                      mode                       text
                       "r"                     "text"
                    opened                   can read
                  "closed"                      "yes"
                 can write
                      "no"

5- changing options does fix anything

options(useHTTPS=TRUE)

6- I have now installed and loaded BiocInstaller 1.18.5 and tried again

> BiocInstaller:::.protocol()
Error in get(name, envir = asNamespace(pkg), inherits = FALSE) :
object '.protocol' not found

score 0 · Answer 5 · 2015-11-16

for 4- I get the number of lines with http:

> length(readLines(file("https://bioconductor.org")))
Error in readLines(file("https://bioconductor.org")) :
cannot open the connection
In addition: Warning message:
In readLines(file("https://bioconductor.org")) :
InternetOpenUrl failed: 'An error occurred in the secure channel support'

but :

> length(readLines(file("http://bioconductor.org")))
[1] 411

5 - Sorry, it was "DOES NOT fix anything"

6- After choosing the repository, I selected 'BiocInstaller' in the list of packages to be installed. Typing the command you suggested confirms its version 1.18.5 I will download:

> source("http://bioconductor.org/biocLite.R")
Bioconductor version 3.1 (BiocInstaller 1.18.5), ?biocLite for help
A newer version of Bioconductor is available for this version of R,
?BiocUpgrade for help

7- Trying to upgrade as suggested above produce mixed results, I guess again due to "https".

> biocLite("BiocUpgrade")
Upgrade all packages to Bioconductor version 3.2? [y/n]: y
trying URL 'http://bioconductor.org/packages/3.2/bioc/bin/windows/contrib/3.2/BiocInstaller_1.20.0.zip'

>

But now :

> BiocInstaller:::.protocol()
[1] "https:"

and :

> file("https://bioconductor.org")
               description                      class

                      mode                       text
                       "r"                     "text"
                    opened                   can read
                  "closed"                      "yes"
                 can write
                      "no"

Yes Jim Java,

it seems that after, R accept the commands with https, that did not work formerly:

> options(download.file.method="libcurl", url.method="libcurl")
> source("https://bioconductor.org/biocLite.R")
Bioconductor version 3.2 (BiocInstaller 1.20.0), ?biocLite for help
>

or :

> length(readLines(file("https://bioconductor.org")))
[1] 411

I'm able to cause a problem similar to yours on a Windows 10 upgrade. If the FIPS security mode is turned off, running

source("https://www.bioconductor.org/biocLite.R")

in R fails; if I turn FIPS mode on, it works. Microsoft apparently doesn't recommend FIPS mode any more, but that may not keep its settings from causing a few problems still.

Your solution might be changing a registry entry. See here for details; in short, you could try changing the Windows registry key

[HKEY_LOCAL_MACHINE\System\CurrentControlSet\Control\Lsa\FIPSAlgorithmPolicy]

to the value 1. Then relaunch R from a fresh command line or GUI and try the source() above again. If you need FIPS mode turned off for some reason, then starting an R session with

options(download.file.method="libcurl", url.method="libcurl")

or adding that line to your .Rprofile file might solve your problem.

Thanks Jim Java,

The packages are now loaded, and prefer not to change the windows register. I will had the options setting you suggest in the function .First I have customized for my applications so to avoid proplems in the future.
