Thanks for the feedback. I don't remember making such mods, and I am using the latest Rcpp, but to be safe I reinstalled Rtools43 and R 4.3.0 and the problem is resolved! Sorry about the false alarm.
Actually, I had two different installations of Rcpp, one under Program Files\R\R-4.3.0, and one under the directory pointed to by R_LIBS_USER (c:\w\R\4.3). I think R now uses some directory under \Users\name\AppData for user packages by default. There may have been a small change with 4.3 in the way R_LIBS and R_LIBS_USER are handled, in that the latter must be used to get local packages NOT to be installed under \Users\name\AppData.
