setequal() with grouped data frame produces error in dplyr 0.7.6

[Eli-Berkow]

Using setequal() with a grouped data frame produces an error using dplyr 0.7.6

library(dplyr)
x <- iris %>% group_by(Species)
setequal(iris, iris)
setequal(iris, x)
setequal(x, iris)
setequal(x, x)

Output:

> setequal(iris, iris)
TRUE
> setequal(iris, x)
TRUE
> setequal(x, iris)
Error in grouped_df_impl(out, group_vars(x), group_drop(x), FALSE) : 
  Could not convert using R function: as.data.frame.
> setequal(x, x)
Error in grouped_df_impl(out, group_vars(x), group_drop(x), FALSE) : 
  Could not convert using R function: as.data.frame.

Using the development version dplyr 0.7.99.9000 I get the following:

> setequal(x, iris)
Error in grouped_df_impl(out, group_vars(x), group_drop(x), FALSE) : 
  unused arguments (group_drop(x), FALSE)
> setequal(x, x)
Error in grouped_df_impl(out, group_vars(x), group_drop(x), FALSE) : 
  unused arguments (group_drop(x), FALSE)

Thanks, confirmed. Fixed in master, we might want to release 0.7.7. Please ungroup arguments to setequal() for now.

Closing as this is fixed in master.

Added this to the new r-0.7.8 branch, should we ever want to submit another minor update.
