Question

when I run the following:

library(devtools)
install_github('roxygen2')

I get the following error:

with devtools 0.51:

Installing roxygen2 from hadley
Error in unzip(src, list = TRUE) : 
  zip file '/tmp/Rtmp2b44Ug/hadley-roxygen2.zip' cannot be opened

I installed a more recent version (0.6) of devtools: install_github('devtools')

and the error is more informative, but similar:

> install_github('roxygen')
Installing github repo(s) roxygen/master from hadley
Installing roxygen.zip from https://github.com/hadley/roxygen/zipball
Error in expand(src, list = TRUE) : 
  zip file '/tmp/Rtmp2b44Ug/roxygen.zip' cannot be opened
In addition: Warning message:
In expand(src, exdir = tempdir()) : error 1 in extracting from zip file

Am I doing something wrong?

Answer 1

This error occurs because the function install_github sets username='hadley' by default (see install-github.r source)

In this case, there is no github branch hadley/roxygen, and now download from https://github.com/hadley/roxygen/zipball/master

This will work:

install_github('roxygen',username = 'klutometis')

note: even though the package is called roxygen2, the “repo” name is “roxygen”
