Hi Charlie,
Thanks, I got it working by looking at your myRunIfConcise function.
SEXP changePercent(SEXP pBar)
{
int *rPercentComplete;
SEXP utilsPackage, percentComplete;
PROTECT(utilsPackage = eval(lang2(install("getNamespace"),
ScalarString(mkChar("utils"))), R_GlobalEnv));
*rPercentComplete = 10; //this value increments
eval(lang4(install("setTxtProgressBar"), pBar, percentComplete,
R_NilValue), utilsPackage);
}
Now I am wondering why the pBar doesn't show initially if the percent complete
is 0%?
Thanks again,
Erik
