Hello,
The first time in a session I call .packages( all.available = T ), it
takes a long time (I have many packages installed from CRAN):
> system.time( packs <- .packages( all = T ) )
user system elapsed
0.738 0.276 43.787
When I call it again, the time is now much reduced, so there mu
The caching is in the disc system: you need to find and read the
package metadata for every package. AFAIK it is not easy to flush the
disc cache, but quite easy to overwrite it with later reads. (Google
for more info.)

I am often confused by the result of the profiler, when a loop is
involved. Consider these two scripts:

Please find attached a patch against svn implementing this proposal.
The part I don't fully understand is the part involving the function
loopWithContect, so I've put "[loop]" in there instead of "[for]",
"[while]" or "[repeat]" because I don't really know how to extract the

There is a bug in 'anova.gls' in the 'nlme' package (3.1-90). The=20
bug is triggered by calling the function with a single 'gls' object=20
and specifying the 'Terms' argument but not the 'L' argument:

Dear Martin,
Thanks a lot for your help, apologies for this very late reply. I
decided to go with your suggestion, write a regular function. I guess
this avoids doing
obj <- as(foo(as(obj, 'Base')), 'Derived')
and then repopulating the extra slots of of the 'Derived' class.

no argument) should call the next method "with the arguments
to the current method passed down to the next method".
But, for the "[[" and "[" generics (primitives), the argument
after the dots doesn't seem to be passed down:
