I´m asked to obtain the life_expectancy median per region:

Gap %>%
      group_by(region) %>%
      summarise(Median = median(life_expectancy))

But also, mean and standard deviation.

Is there another function simplier that writing all this code?

Thank you in advance!

    Not sure what you mean, this isn't much code (I guess that's relative) and you've only calculated 1 of the 3 summary statistics you say you need – camille Nov 14 '21 at 19:42

library(dplyr)
mtcars %>%
  group_by(cyl) %>%
  summarize(across(mpg, list(med = median, mu = mean, sigma = sd)))
# # A tibble: 3 x 4
#     cyl mpg_med mpg_mu mpg_sigma
#   <dbl>   <dbl>  <dbl>     <dbl>
# 1     4    26     26.7      4.51
# 2     6    19.7   19.7      1.45
# 3     8    15.2   15.1      2.56

    Would it be an idea to add this answer to the above suggested very much duplicate question instead? – tjebo Nov 14 '21 at 19:51
