loading dplyr after plyr is causing issues

Question

Test Case:

library(dplyr)
library(plyr)
library(dplyr)
mtcars%>%rename(x=gear)

This gives error. Any help would be greatly appreciated.

I have this problem when require plyr again sourcing files. You can do

if("dplyr" %in% (.packages())){
          detach("package:dplyr", unload=TRUE) 
          detach("package:plyr", unload=TRUE) 
} 
library(plyr)
library(dplyr)
