gplots dependency for a vignette

[evelynmitchell]

Building the vignettes fails because gplots isn't installed: Error: processing vignette 'textplotPresentation-CRUG-2011.Rnw' failed with diagnostics: chunk 4 (label = gplotstextplot) Error in library(gplots) : there is no package called ‘gplots’

After installing gplots, the same vignette errors on Hmisc: Error: processing vignette 'textplotPresentation-CRUG-2011.Rnw' failed with diagnostics: chunk 5 (label = Hmiscformat) Error in library(Hmisc) : there is no package called ‘Hmisc’

The pdf of that presentation is available. Suggested alternatives to fix: add gplots and Hmisc as a dependency use this as a pdf only vignette (I don't know if this is allowed).
