search for: do_while

This patch is against current svn and contains three classes of fix: - Ensure the result is properly terminated after calls to strncpy() - Replace calls of sprintf() with snprintf() - Added a PROTECT() call in do_while which could cause memory errors if evaluating the condition results in a warning. Thanks, Karl

I have an R script that I run using nohup R CMD BATCH r.in r.out & The code loops through data from the database and takes hours.

Dear all, First, I recently had reasons to read the help page of as.vector() and noticed in the example section the following example: x <- c(a = 1, b = 2) is.vector(x) as.vector(x) all.equal(x, as.vector(x)) ## FALSE However, in all versions of R in which I executed this example, the all.equal command returned TRUE which suggest that either the comment in the help file
