It seems that when dtplyr is installed with dplyr and data.table I get this issue
library(dplyr)
library(data.table)
library(dtplyr)
dt1 = mtcars
# works as expected
dt1 %>% count(cyl)
# # A tibble: 3 x 2
# cyl n
# <dbl> <int>
# 1 4 11
# 2 6 7
# 3 8 14
# used to work but not now
setDT(dt1) %>% count(cyl)
# Error in .subset(x, j) : invalid subscript type 'list'
That used to work, but not at the moment. Why is this happening?
Also, when I run this process without dtplyr it works, but without having the advantages that dtplyr offers.
I'm using up to date versions of those packages (dplyr 0.7.0, data.table 1.10.4, dtplyr 0.0.2).
