[R-sig-Geo] raster:::stack(), missing value where TRUE/FALSE needed

[Howard, Tim G (DEC)]

I'm kind of at a loss as to why 

"Error in if (common.len == 1L) unlist(x, recursive = FALSE) else if (common.len :
missing value where TRUE/FALSE needed"

means "your system can't handle such big files" but switching to a computer with Windows 64-bit and 32GB RAM seems to solve the problem. 

I'm all set now.
