Peter,
the changes you made should be ok. (No changes are needed for gcc/g++
anyway.) The problem is not the C compiler, which is (most likely)
gcc, but the c++ compiler, which is not the GNU

is called g++ or gxx. If you found

the problem is that Apple's FreeType on Leopard uses CF calls (albeit
just to get files), so it breaks on fork. (The message is moot,
because the whole point of using fork is to *not* use exec).
In any case the solution is to compile your own version of freetype,

Stata option vce cluster in the mlogit command but was looking for a similar
functionality in R too...
thanks all!

Hi!
I have a set of 800 coordinates pairs and need to find the distance
between each pair.
I am able to find the distance between one pair using:
<-geodist(LatStart,LongStart,LatEnd,LongEnd,units="km")) but doing one
by one is nor feasible.
Can you help me?
Thanks, Mafalda

Another option is to modify the Rprofile.site file in the etc folder of
your R installation. Then you don't have to save the workspace. You add
as much startup scripting as you want to the Rprofile.site file.

Dear all
I want to display 4 dimensional space by some suitable way. I searched
CRAN and found miscellaneous 3 dim graphics packages which I maybe can
modify but anyway I am open to any hint how to efficiently display data
like:
longitude, latitude, height, value
Thank you

This will explain things.
You make a hidden program called .First like this
.First <- function() { library(lattice) }
and then save your workspace. The next time you open R, lattice will load
automatically.

Hi,
I have two questions about ts.

Dear baseRs,
I recently made a mistake when renaming data frame columns, accidentally
creating an NA column. I found the following strange behavior when negative
indexes are used.
Can anyone explain what happens here. No "workarounds" required, just curious.
