"loop_apply" not resolved from current namespace when using ddply()

[tekr]

I get this error intermittently using plyr from CRAN and GitHub with the latest R version (3.2.1).

I say intermittent, because restarting R Studio fixes it for some time, and it also seems somewhat dependent on what (if any) other packages I have loaded besides plyr.

The thread here regarding a similar error in a different package suggests it is due to a missing PACKAGE parameter on the call to .Call() in loop_apply.R, and indeed adding the parameter fixes the issue for R 3.2.1 (pull request to follow).

Note I have not tested the fix in older versions of R.

I started getting this error today when trying to use ggplot2. I installed plyr from source into R-devel_2015-10-09 itself compiled from source.

I think this was fixed by 3256bb5
