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%?
