RTools Not Available?

This is slightly related, though the solution was to reinstall Rcpp.

Issues with loading semPlot

Thanks, @gueyenono ! I've tried your method, but still error report when I library semPlot: Error: package or namespace load failed for ‘semPlot’: .onLoad failed in loadNamespace() for 'OpenMx', details: call: fun(libname, pkgname) error: function 'Rcpp_precious_remove' not provided by package 'Rcpp' Any other suggestions? Thank you very much!
