Thanks for your interest in the package! Sorry it took my so long to answer this. Please get back, if you got it to work in the meantime!

I am not exactly sure what causes this error, but it seems that there is a problem with installing the Rcpp dependency. try installing the Rcpp package before installing caspr.

install.packages("Rcpp")
