I'm developing an R package, and when I recompile (using Roxygen), detach, and re-load the package, I can't seem to look at some of its documented functions. When I try '?function.name', I get the following error:Error in tools:::fetchRdDB(RdDB, basename(file)) : cannot allocate memory block of size 2.6 Gb I'm using R.app's built-in documentation viewer. I don't get the same error when I look at the docs for built-in functions, e.g. '?cos' works fine. Most of the .Rd files spit out by Roxygen are very simple, e.g. here's one that fails to be viewed, it has only 4 lines: in man/ndcg.Rd: \name{ndcg} \alias{ndcg} \title{ndcg} \usage{ndcg(pr, position=5, ...)} Anyone have any thoughts?
(1) Package development is an R-devel topic -- please see the posting guide.
(2) Either the package has an enormous amount of documentation or (more likely) the on-disc .Rd database for the package is corrupt. Have you tried removing completely any previous installation and re-installing -- that usually fixes similar errors?
(3) The 'minimal, self-contained, reproducible code' comment is likely to apply if (2) does not solve this.
Here's my R.version:
Next time please give the information in the format the posting guide requested.
