dyn.load (PR#9364)
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 I was just testing this myself on various machines. And it behaves on Linux, Windows and also on my Intel Mac (OS X 10.4.8). Stefano, is this restriction on OS X still in effect? (Unfortunately I can't test this on any of my Power PC macs just at the moment. Just building R-2.4-0 one one of them.) There is test code available at www.omegahat.org/Misc/Rdynunload.tar.gz The script run.R does the builds and load and unloads and runs the entire test. Without a programmatic test it is easy to test the wrong thing. D.

In OS X you cannot "unload" dynamically linked code. This is a known "feature" of OS X :( This is not an R bug. stefano On 15/nov/06, at 15:27, tuke at senet.com.au wrote:

I am writing C code to implement in R. I am using R CMD SHLIB and then
dyn.load("file.so"). The function I then call with .C("function").
Since I
installed the latest R version, I have found that if I alter my C
code and
recompile, then use dyn.load("file.so"), the function in R is not
updated but
remains as the previous code. I have tried dyn.unload, but when I
use dyn.load()
the initially loaded code is used. The only way to load the updated
c code is to
quit R and then reopen.
Thanks,
Jono
