I have to install the package "fixest" for an assignment and everytime I try to install it I get the following error.

Error: package or namespace load failed for ‘fixest’: .onLoad failed in loadNamespace() for 'fixest', details: call: cpp_get_nb_threads() error: function 'Rcpp_precious_remove' not provided by package 'Rcpp'

I was getting a problem when knitting and I had to install knitr

Can someone please help me with that?

  • Try upgrading your version of Rcpp. It appears (though I'm no expert) that this was added a couple of years ago (https://github.com/RcppCore/Rcpp/blame/519909c579a3ff9f185a86afd579718f0aa16351/inst/include/RcppCommon.h#L81). Then try to reinstall `fixest`. – r2evans Sep 16 '22 at 17:22
