Is there a way I can check what the following code does in a previous version of dplyr?
tibble(a = c(1,1,2,3)) %>% count(a) %>% add_count(a)
I'm running version 0.8.3 in R 3.6.1, this is the result:
# A tibble: 3 x 2
a n
<dbl> <int>
1 1 1
2 2 1
3 3 1
And I'm pretty sure that in a previous version the result would have been an added column nn
, like:
# A tibble: 3 x 3
a n nn
<dbl> <int> <int>
1 1 2 1
2 2 1 1
3 3 1 1
But I need to be sure and prefer without re-installing dplyr in a previous version, then re-installing the latest etc.
Thanks.

One option is to have multiple libraries:
Personally, I'll keep an rstudio cloud project with older versions. For example, here's the output from dplyr 0.7.6
library(dplyr)
tibble(a = c(1,1,2,3)) %>% count(a) %>% add_count(a)
#> # A tibble: 3 x 3
#> a n nn
#> <dbl> <int> <int>
#> 1 1 2 1
#> 2 2 1 1
#> 3 3 1 1
Also linking to the issue you filed, so the thread and issue can stay together
