When working in a script file, standard data frames, tibbles, and grouped tibbles all print differently to the console. In a notebook, when printing output from multiple function calls, a grouped tibble yields results that are labeled as "grouped_df" in the icons that represent each piece of output, but the information regarding which variables they're grouped by is missing. If the only output in a chunk is the printout of a grouped tibble, there's no indication at all that it's grouped. Is that a bug, or by design? Or am I missing something simple that's suppressing it?
Running the example below in a script window and then in an rmd window will demonstrate how different the two displays are.
Thanks,
Bob
group <- c("A","A","B","B")
x <- 1:4
my_df <- data.frame(group, x, stringsAsFactors = FALSE)
library("dplyr")
my_tibble <- data_frame(group, x)
my_tibble_grouped <-
my_tibble %>%
group_by(group)
print(my_df)
print(my_tibble)
print(my_tibble_grouped)
