I'm trying to use `BioConductor` with my `R` installed through `conda`.

I get this error:

```

jespinozlt-osx:~ jespinoz$ which R

jespinozlt-osx:~ jespinoz$ R

I guess a minimal reproducible example is file("https://bioconductor.org/biocLite.R"). I don't think it's a problem with Bioconductor's certificates, but instead that libcurl (the default method for https) is not finding the CA certificates bundle. I don't know whether this is influenced by your anaconda or not, and if it is I don't have any suggestions.

You could try curl -I https://bioconductor.org/biocLite.R from the command line. If that fails then the task is to get an updated CA certificate bundle in the right location for cURL.

A work-around is to use http: rather than https, but that's not a very good idea.

I tried http and was getting the same problem :( when I get back to my computer I will try the curl method. Using R w/ conda is a little buggy.

Try also options(useHTTPS=FALSE) with the http:// url.

I didn't get an error when I ran the `curl` line but I'm getting that my `R` version isn't compatible with `biocLite`

Does the suggestion to

options(useHTTPS=FALSE)
install.packages("BiocInstaller", repos="http://bioconductor.org/packages/3.3/bioc")

get BiocInstaller installed, and biocLite() install default packages?
