Dear all
is there any linear programming routine available for R?
if not, can you suggest any alternatives? not need to be very powerful, I
get only a samll problem to resolve.
many thanks

The first menu item on the `File' menu is called `Source R code' and calls
source(). Did you look through the menus? If not, it would be worth
familiarizing yourself with them.

Hi!
If I have similar problem.
I first run R CMD check. Then I change to the directory mypackage.Rcheck where R CMD

Then I try to compile the file using latex by myself. In addition I am using a latex

I don't see why this needs to be iterative: the computations could be done
in parallel. But via a for loop you could use
for(i in 1:122) {

assign(nm, log(get(nm))
