dplyr summarise_each with na.rm

Question

Is there a way to instruct dplyr to use summarise_each with na.rm=TRUE? I would like to take the mean of variables with summaris

Answer 1

Take for instance mtcars data set

library(dplyr)

You can always use summarise to avoid long syntax:

mtcars %>%
  group_by(cyl) %>% 
  summarise(mean_mpg = mean(mpg, na.rm=T),
            sd_mpg = sd(mpg, na.rm = T))
