Working on my R bootcamp materials and I thought it would be handy to get the bootcamp computers setup by sourcing an R script that will install all necessary non-core packages in it. The problem? How to deploy this script efficiently. A quick method would be to simply source the script from a public Dropbox share. But, as the BioBucket points out, it isn’t that straightforward!
So I created a simple little function called source_dropbox to handle this work. It is hosted as a Gist on GitHub for others to use.

# myurl must be a character string with the full public link of the script file | |
# Problem--we can't use URL shorteners | |
dropbox_source<-function(myurl){ | |
s<-str_extract(myurl,"[/][a-z][/]\\d+[/][a-z]*.*") | |
new_url<-paste("http://dl.dropbox.com",s,sep="") | |
source(new_url) | |

Next up, sourcing a Gist!
