[Rd] assignment

In a recent SO post this came up (changed example to simplify it here). It seems that `test` still has the value sin. test <- sin environment(test)$test <- cos test(0) ## [1] 0 It appears to be related to the double use of `test` in `$<-` since if we break it up it works as expected:
