[R] using getBioC()

There was a post in the Bioconductor mailing list regarding the same
error message:


One possible solution mentioned there was to remove the line in
getBioC() that checks the capabilities. Since it seems likely that you
do have access to http from your machine, even if the R version doesn't
know that, then you could try saving the script to a local file, edit it
to change the line that reads:

http <- as.logical(capabilities(what="http/ftp"))

##http <- as.logical(capabilities(what="http/ftp"))
http <- TRUE

then source your local copy of the file, and finally try re-running the

I don't understand why the capability would be detected as FALSE. I
built my version on Linux, but never made any explicit selection of the
capability. I do see some other items listed by the capabilities()
function that I did configure. (It wouldn't be some oddity of the Mac OS
would it?...)

Anyway, I hope this helps.
