Hi, what version of R is this? Apparently the fastmap package fails to compile here.

One workaround is to use Posit Package Manager which has binary packages for older versions of R, so you don't need to compile them from source. They seem to have a binary for the lastest fastmap version, for R 3.6.x. So you can do this:

options(repos = c(
  PPM = "https://packagemanager.rstudio.com/all/latest", 
  CRAN = "https://cloud.r-project.org"
))
install.packages("fastmap")
install.packages("shiny")
