please re-install
it". But then if I remove my private library from the search path I can
load foreign....so this suggests the problem is with the foreign package
in my 'private library'.
Furthermore, if I look at the description file for foreign it claims to
have been built for R package 2.9.2. (I've copied it below).
I'm concluding the issue is with the foreign package in my private library
since it claims to have been built for R 2.9.2& I can get the package to
load if I remove my private library from the library search path and laod
the foreaign package from the base library.
I'm then concluding the problem is due to it not updating since
the description file claims it was built for R version 2.9.2 and due to
the error message I'm getting ie "foreign' was built before R
2.10.0: please re-install it"
BUT I'm happy to be proven wrong... I just can't think of what else the
problem could be?????

Subject: Re: [R] is there a way to update both packages if they occur in 2
libraries?
update.packages() updates all packages in all libraries listed in
.libPaths() unless you specify an explicit library.
It may happen that the version number has not changed and you just want
to reinstall for your upgraded R. In that case use:
update.packages(checkBuilt=TRUE)
Best,

Hi everyone,
I've recently added a private library as a way to manage my R libraries.
And
I did this by simply copying my old library to a new folder and then
linking
this to R by setting my R_LIBS environmental variable in .Renviron.
However I have run into a problem.
When I update my packages it is not updating those that are current in
the
base R library.
This means I can't load packages that are included in base R, since R is
looking in my private library first and when it finds the package it
tries
to use it. But it's an outdated version.
The easiest solution I can think of is to update both libraries, but
when I
run update.packages(lib.loc="private library location" ask = FALSE,
checkBuilt=TRUE) it's not updating them.
So I was wondering if there is a way to update all packages that occur
in
all libraries?
(Note that I can think of other solutions to my problem, but they are
all
time consuming and defeats the purpose of why I want a private library
i.e.
it makes updating R easier since I don't need to copy over the library
folder each time nor update any environmental variables. So far the best
alternative I've come up with is to delete all the duplicate base R
libraries from my private library)
If anyone is interested the code I used to understand my problem is
below.
Thanks everyone
update.packages(lib.loc="C:\\Program Files\\R\\library", ask = FALSE,
checkBuilt=TRUE)
--- Please select a CRAN mirror for use in this session ---
update.packages(ask = FALSE, checkBuilt = TRUE)
