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

fs <- c("min", "max")
