Subject: Removing or ignoring package version for generic function in locked environment
Hi,
I use the epicalc package which provides the function aggregate.numeric.
Unfortunately aggregate.numeric produces warnings when aggregate is used by functions not under my control on a numeric value. If I don't load epicalc, aggregate.default is used instead by these functions and does not produce any warning.
However I need epicalc. So to get around this, what I would do is firstly remove aggregate.numeric:
rm(aggregate.numeric, pos=which(search() == "package:epicalc"))
This worked fine in R 2.13.1. However in R 2.14.0 I am getting the following:
Error in rm(aggregate.numeric, pos = which(search() == "package:epicalc")) :
cannot remove bindings from a locked environment
Is there some way I can remove aggregate.numeric, or otherwise prevent it from being used?
Thanks in advance,
Oliver
