assigning to list element within target environment
...e the unneeded variable
rm("temp",envir=testEnv)
But I figure there must be a more elegant way. Anyone have any ideas?
Thanks,

Loops
Dear Contributors,
I am asking help on the way how to solve a problem related to loops for
that I always get confused with.
I would like to perform the following procedure in a compact way.
Consider that p is a matrix composed of 100 rows and three columns. I need
to calculate the sum over some rows of each
column separately, as follows:
fa1<-(colSums(p[1:25,]))
fa2<-(colSums(p[26:50,]))

long double, C, fortran
...back to doubles?
3. Will calls to FORTRAN BLAS (like dsymv, dpotrf, dpotri) still work
with long doubles?
Thanks for any help you can provide.
