Unable to install without 'knitr' - move to Depends?

[tmelliott]

I see the 'knitr' package is listed under suggests, but when installing from source I get:

> install.packages("expss")

However if I install knitr, it works fine, so I assume it's related to NAMESPACE exports and 'knitr' probably should be moved to Depends?
