I remove plyr, load dplyr and check the current packages



detach("package:plyr", unload=TRUE)

library(dplyr)

(.packages())



[1] "dplyr" "bindrcpp" "stats" "graphics" "grDevices"
"utils" "datasets"

For info here are the conflicts:



conflicts()



[1] "filter" "lag" "body<-" "intersect" "kronecker"
"setdiff" "setequal"

[8] "union"




Then I use summarise and get the error. This is the same code that I used 6 months ago without issue.



by_vs_am <- group_by(mtcars, vs, am)

by_vs <- summarise(by_vs_am, n = n())



Error in summarise_impl(.data, dots) : Evaluation error: This

Try use dplyr::n() instead.
The code should look like this:



by_vs_am <- group_by(mtcars, vs, am)

by_vs <- summarise(by_vs_am, n = dplyr::n())
