I am trying to install bioconductor through source("http://bioconductor.org/biocLite.R") but I am getting this message
"Bioconductor version 3.5 (BiocInstaller 1.26.0), ?biocLite for help"
thats why its difficult to run the code further. Please give me suggestion
Thanks
Thank you
I want to use Biostrings it gives this messsage and somtimes says that biostrings package not found.
> biocLite("Biostrings")
BioC_mirror: https://bioconductor.org
Using Bioconductor 3.5 (BiocInstaller 1.26.0), R 3.4.1 (2017-06-30).
Installing package(s) ‘Biostrings’
Warning: package ‘Biostrings’ is in use and will not be installed
Restart and R and install it from a clean R session.
The message tells you that Biostrings is already loaded and it doesn't want to install a new version over it while it's in use.
I did but even afer installing Biostring i am getting this message
> ?biostrings
No documentation for ‘biostrings’ in specified packages and libraries:
you could try ‘??biostrings’
There is no function called biostrings, so you won't get a help page. What exactly are you expecting ?biostrings to do for you?
myrawfile <- readRNAStringSet("abc.fasta")
Error in .Call2("new_input_filexp", filepath, PACKAGE = "XVector") :
cannot open file 'abc.fasta'
Thats why I am not able to read fasta file in R
That's the error you get if you try to open a file that isn't there:
> readRNAStringSet("theresnofilehere.fasta") Error in .Call2("new_input_filexp", filepath, PACKAGE = "XVector") : cannot open file 'theresnofilehere.fasta'This doesn't prove anything. The following does, and should work for you:

Error in readDNAStringSet(filepath1) :
could not find function "readDNAStringSet"
I dont know what going wrong. It is also not working. Please guide me I am not good in R thats why.
source("http://bioconductor.org/biocLite.R")
biocLite("Biostrings")
library(Biostrings)
filepath1 <- system.file("extdata", "someORF.fa", package="Biostrings")
readDNAStringSet(filepath1)
I tried this but not working ang says there is no Biostrings package
We need to take a step back here and make sure that Biostrings installs correctly. You also need to provide more of R's error messages instead of your interpreted summary of what you think is going wrong.
For example, your "... says there is no Biostrings package" paraphrasing isn't exactly helpful, because we don't know what the exact error message was, or exactly when it was printed. Those two things are important for us to help you help yourself
So, please restart R so you that have a clean workspace (again) then run the following:
Please copy and paste all of the output that follows the
biocLitecall.After you copy paste that, please run the following command:
And copy and paste all of the output from that.
This worked out
source("http://bioconductor.org/biocLite.R")
biocLite("Biostrings")
require(Biostrings)
filepath1 <- system.file("extdata", "someORF.fa", package="Biostrings")
readDNAStringSet(filepath1)
Now another problem is
source("http://bioconductor.org/biocLite.R")
biocLite("Rsamtools")
require(Rsamtools)
> require(Rsamtools)
Loading required package: Rsamtools
Warning message:
