Hi! I'd like to do SEM, but it seems I can't library semPlot. Anyone know how to solve this? My R version is 1.4.1103. Error report below:
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'
Thanks a lot.
