Installing RExcelXML from The Omega Project in R

A quick post to capture the resolution to the past 20 minutes I have spent in frustration trying to install RExcelXML from Omegahat (The Omega Project for Statistical Computing). As this is a source package, the dependencies need to be satisfied manually (which is a bit baffling, frankly — surely there is a workaround for this using a makefile-like facility in install.packages()). The package depends on ROOXML, Rcompression and XML. The solution is two-staged:
 
> install.packages(c('Rcompression', 'XML'))
> install.packages(c('ROOXML', 'RExcelXML'), repos = 'http://www.omegahat.org/R', type = 'source')

Back to the grind …
