Failed to build Vignette when using suggested code

Error: Failed to install 'GridLMM' from GitHub:
! System command 'Rcmd.exe' failed

when running suggested code
devtools::install_github('deruncie/GridLMM', build_opts = c("--no-resave-data", "--no-manual"),force = TRUE,build_vignettes = TRUE)

Try running with build_vignettes = FALSE to see if that is the problem. I pushed a fix to an error in one of the vignette sections. If that doesn't help, can you give more information about your system? The code runs fine on my mac and my linux cluster. Do you get any other error messages? Are you able to compile other packages that use Rcpp?
