Rook provides an interface for R programmers to build web applications which can run in R 2.13′s built-in web server or (soon) rApache.
Jeffrey’s provided some great documentation and sample code on his blog, in the README file, and in the package documentation itself, but somehow I completely missed the importance of the Rhttpd class and couldn’t figure out how to load or launch any of the examples.
Hopefully I can save someone some similar head-scratching. The key is the Rhttpd class, which controls the web server and manages applications. By default it will install the “RookTest” example, so here are 4 lines you need to see it work:
> library(Rook) > s s$start(quiet=TRUE) > s$print() Server started on 127.0.0.1:31839  RookTest http://127.0.0.1:31839/custom/RookTest Call browse() with an index number or name to run an application.
[EDIT: Thanks to Jim Porzak to pointing out that
browse() is a method on the Rhttpd object rather than an old school package-scoped function. Times are a-changin'... for the better!]
browse() function didn’t seem to work for me,
s$browse(1) will load the URL into your browser or you can just copy-and-paste to access the running application:
