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

summarise_at function in dplyr will summarise a dataset at specific column and allow to remove NAs for each functions applied. Take iris dataset and compute mean and median for variables from Sepal.Length to Petal.Width.

library(dplyr)
summarise_at(iris,vars(Sepal.Length:Petal.Width),funs(mean,median),na.rm=T)
