Description Kyle Simek 2014-12-15 07:13:46 UTC
version: 3.1-118 
library: nlme 
file: R/corStruct.R
line: 1411

Due to a typo in the method name, corCompSymm objects call the base-class's corFactor method instead of its specialized version.  

At line 1411 of R/corStruct.R, the declaration

    corFactor.compSymm <- ...

should be 

    corFactor.corCompSymm <- ...

This bug shouldn't affect correctness, because the base-class method implements the same semantics as the derived class, but I assume the specialized method is likely more efficient.

Disclaimer: I'm new to R and wasn't able to confirm this bug or the proposed fix in a debugger.  I hope maintainers who know more than me can check that my suggested fix makes sense, and apologies in advance if this is off base.
