Hi,

I installed package 'lars' earlier tonight and did not get any sort of 
error message.

###
** building package indices ...
** testing if installed package can be loaded
Loaded lars 0.9-8

* DONE (lars)
###

However, when I try to load it, I get
###

Error : .onLoad failed in loadNamespace() for 'lars', details:

I get the same error message when I try to load it on another machine:

Is there at least a way to circumvent the problem?

Thank you for your help,

Hello,

I do think so.

###

I re-installed it and I still get the same error message.

It is the first time I get such an error message when trying to load a package. It would seem that the problem is with

###
cat("Loaded lars", utils::installed.packages()["lars", "Version"]
###

Is there a way to circumvent this problem (e.g. attribute an arbitrary value to utils::installed.packages()["lars", "Version"])?

Thanks for your help,

Luc

I haven't looked closely enough before:

The culprit is in lars which has:

cat("Loaded lars", utils::installed.packages()["lars", "Version"],

and hence only looks at the default search path to report its version 
while you supplied a different one.

Thus, it is a bug in the package you should report to its maintainer.

I the meantime as a workaround (and maybe more convenient anyway): set 
the location of your library using .libPaths() before loading the package.
