A list of functions specified by:

  • Their name, "mean"

  • A call to the function with . as a dummy parameter, mean(., na.rm = TRUE)

args

A named list of additional arguments to be added to all function calls.

Examples

Run this code
funs(mean, "mean", mean(., na.rm = TRUE))

# Overide default names
funs(m1 = mean, m2 = "mean", m3 = mean(., na.rm = TRUE))

# If you have function names in a vector, use funs_
fs <- c("min", "max")
funs_(fs)
