Error: package or namespace load failed for ‘glmmTMB’

Question

I am trying to use package glmmTMB. When I call library(glmmTMB) this is the error message:

">library(glmmTMB) Error: package or namespace load failed for ‘glmmTMB’ in inDL(x, as.logical(local), as.logical(now), ...): function 'Rcpp_precious_remove' not provided by package 'Rcpp' In addition: Warning messages: 1: package ‘glmmTMB’ was built under R version 4.0.5 2: In checkMatrixPackageVersion() : Package version inconsistency detected. TMB was built with Matrix version 1.3.4 Current Matrix version is 1.2.18 Please re-install 'TMB' from source using install.packages('TMB', type = 'source') or ask CRAN for a binary version of 'TMB' matching CRAN's 'Matrix' package

I have tried using install.packages('TMB', type = 'source') with no luck. Any ideas?

Answer 1

It's a FAQ -- search for 'Rcpp_precious_remove' not provided by package 'Rcpp'.

In short you are mixing a NEWER compilatio nof something that was built with Rcpp 1.0.7 present with an older installed version which lacks the symbol.

Fix: install.packages("Rcpp") to get the newer Rcpp. And I generally recommend regular update.packages() runs to avoid these issues.
