Dear R-SIG-Fedora, I'm finding that on CentOS 7, rgl.snapshot (a function in the R package rgl, which provides an R interface to the OpenGL 3-d graphics library) only captures a small portion what's visible in the RGL device window. This does not happen with the same R and rgl versions on CentOS 5.3 (see details below). The maintainer of rgl, Duncan Murdoch, responded (see below) that

Is there some fast (built-in?) way to get the OR of all the elements in a logical vector? In other words, is there some fast (built-in) version of the function vor below? Thanks. -Ben vor <- function(v) { ans <- v[1] if (length(v) > 1) for (i in 2:length(v)) ans <- ans | v[i] ans }

Some time ago I tried to find out how to compute remainders in R. I now know that it is done with %%, which is documented in help('+'), but before someone told me that I tried: help('remainder'), help.search('remainder'), apropos('remainder') help('modulo'), help.search('modulo'), and apropos('modulo') all of which yielded nothing. I then
