After updating lme4 (1.1-12), I'm getting this error when I invoke varComp package.
library(varComp)
Error : object ‘sigma’ is not exported by 'namespace:lme4'
Error: package or namespace load failed for ‘varComp’

The varComp package depends on RLRsim. RLRsim uses the S3 generic sigma, which was moved from lme4 to stats in R 3.3.0. If you use a Windows binary for RLRsim built under R < 3.3.0, then RLRsim will look for sigma in lme4 instead on in stats:
> install.packages("https://cran.r-project.org/bin/windows/contrib/3.2/RLRsim_3.1-2.zip", repos=NULL)
...
package ‘RLRsim’ successfully unpacked and MD5 sums checked
> library(varComp)
Error : object ‘sigma’ is not exported by 'namespace:lme4'
Error: package or namespace load failed for ‘varComp’
If you reinstall RLRsim you should get a recent build and varComp will load:
> install.packages("RLRsim")
...
package ‘RLRsim’ successfully unpacked and MD5 sums checked
...
> library(varComp)
