I have a data frame with 1 grouping column (group.factor) and 49 numeric variables. All I want to do is create a simple table with separate means and sds for each group. I’ve spent an inordinate amount of time trying to figure this out and could really use some help.
Also, I’ve tried this, and have no idea what the error even means.
iris %>%
+ group_by(Species) %>%
+ summarise(across(starts_with("Sepal"), list(mean, sd), .names = "{col}.fn{fn}"))
Error: peek_mask() must only be used inside dplyr verbs
Run `rlang::last_error()` to see where the error occurred.
