Is it fine to download all available packages for R?

Question

[vinayjrao]

Hello,

I am trying to download genefu package in R, and constantly got the error that certain dependencies are not available for biomaRt. I was therefore wondering if it is fine to download all available packages for R? If yes, is there a way to download all packages at once or do I have to mention each package one at a time?

TIA :)

I think this will take a loooong time and will use up a lot of your hard disk space. I would suggest to install the package you need only.

Thanks, but what do I do when it keeps saying that the dependencies are not available?

You can do like this; example installing an arbitrary package called "foo" along with its dependencies:

install.packages("foo", dependencies=TRUE)

genefu is a bioconductor package, so I did the following -

source("http://bioconductor.org/biocLite.R")
biocLite("genefu")

The error I got was -

checking for xml2-config... no

Cannot find xml2-config

The problem is with xml2-config. Check this Also there are many dependencies. Do biocLite() and update, then try one more time.
