[R] Problems with rstan

[david.jessop at ubs.com]

Hi

I'm having a really odd problem with rstan (and in fact shiny), which is I can't actually load the package:

> ls (all=TRUE)
character(0)
> library (rstan)
Loading required package: ggplot2
Error : .onAttach failed in attachNamespace() for 'rstan', details:
  call: pkgdesc$Packaged
  error: $ operator is invalid for atomic vectors
In addition: Warning messages:
1: package 'rstan' was built under R version 3.2.4
2: In packageDescription("rstan", lib.loc = rstanLib) :
  no package 'rstan' was found
Error: package or namespace load failed for 'rstan'

And for shiny

> library (shiny)
Error : .onAttach failed in attachNamespace() for 'shiny', details:
  call: utils::packageVersion("htmlwidgets")
  error: package 'htmlwidgets' not found
Error: package or namespace load failed for 'shiny'

But I have htmlwidgets in our package folder.    So if I then load htmlwidgets and reload shiny everything is happy.   The packages are installed on a shared drive.

My session is
