My system is a Windows 7 and the following function solved the dyn.load.
dynlib.load <- function(x, dir){
dynname <- paste(x, .Platform$dynlib.ext, sep="")
dynname <- file.path(R.home(dir), dynname)
dyn.load(dynname)
}
# In windows it's these names
dynlib.load("Rlapack", "bin")
The rest worked at the first try.
Note that this function is independent of the sub-architecture, like the
help page for R.home() says:
"The return value for "modules" and on Windows "bin" is to a
sub-architecture-specific location. "
(R.home("bin") returns .../bin/i386 or .../bin/x64)
Hope this helps
