funs: Create a list of functions calls.

Description

funs provides a flexible way to generate a named list of functions for input to other functions like summarise_each.

Usage

funs(...)
funs_(dots, args = list(), env = baseenv())

Arguments

dots, ...

A list of functions specified by:

• Their name, "mean"

• The function itself, 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.

env

The environment in which functions should be evaluated.

Examples

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)
