Just wanted to start a discussion on whether R could ship with more appropriate GC parameters. Right now, loading the recommended package Matrix leads to: > library(Matrix) > gc() used (Mb) gc trigger (Mb) max used (Mb) Ncells 1076796 57.6 1368491 73.1 1198505 64.1 Vcells 1671329 12.8 2685683 20.5 1932418 14.8 Results may vary, but here R needed 64MB of N cells and 15MB

Hi all, I've got a basic question regarding package documentation and rd.sty. I wrote my first own package, and now I would like to place the documentation into the appendix of another LaTex document. Seemingly I cannot simply \usepackage{Rd}, as this will modify the page-settings of my document. Is there a minimum style file which will just define the environments and commands needed for
