I am currently having, uh, difficulties, with the latest version of
lme4, which I did not have with an elderly version that I was using
previously. To check things out I installed the elderly version in a
directory called "AltRlib", in my home directory.
I kept the latest version (1.1-5) in a directory called "Rlib" in my
home directory.
I have R_LIBS set equal to "/home/rolf/Rlib" in my environment, so that
"Rlib" gets searched automatically.
If I start R in my home directory and issue the call
library(lme4,lib.loc="/home/rolf/AltRlib")
then I get the elderly version as required.
If I start R in a subdirectory, say "/home/Rolf/Foo" and issue
the *same command*, I get the 1.1-5 version, *NOT* as required.
After some head-scratching I moved the .RData file in "Foo" to
Save.RData and re-started R. ***Then*** I got the version of lme4 that
I wanted.
So I removed all traces of results produced by the 1.1-5 version of lme4
from Save.RData (saving them elsewhere for safekeeping), moved
Save.RData back to .RData, re-started R, issued the library command, and
got the unwanted 1.1-5 version!!!
Can anyone explain WTF is going on? What is hanging around in .RData
that causes library() to ignore the "lib.loc" argument? How can I keep
library() from ignoring the "lib.loc" argument?
Thanks.
cheers,
Rolf Turner
