[R] install.packages and dependencies=TRUE

[Gábor Csárdi]

Dear all,

I am trying to install a private package, with its dependencies. However, both

install.packages("sand_1.0.tar.gz", dependencies=TRUE, repos=NULL,
type="source")

and

install.packages("sand_1.0.tar.gz", dependencies="Suggests",
repos=NULL, type="source")

fail to install suggested packages:

> packageDescription("sand")$Suggests
[1] "network, sna, ape, ergm, mixer, vioplot, ROCR, fdrtool, huge"

Based on the docs, I got the (obviously wrong) impression, that it was
possible to install suggested packages. From ?install.packages,
dependencies argument:

          ‘TRUE’ means to use ‘c("Depends", "Imports", "LinkingTo",
          "Suggests")’ for ‘pkgs’ and ‘c("Depends", "Imports",
          "LinkingTo")’ for added dependencies: this installs all the
          packages needed to run ‘pkgs’, their examples, tests and
          vignettes (if the package author specified them correctly).

> library(ergm)
Error in library(ergm) : there is no package called ‘ergm’
> library(huge)
Error in library(huge) : there is no package called ‘huge’

What am I doing wrong, and more importantly, what is the correct way
to install _all_ dependencies of a package?

Thanks, Best,
Gabor
