I am trying to write a function that will have an input of a vector of

sumstats <- c(mean,sd)
sumstats[1]
#Gives this error

#function (x, ...)
#UseMethod("mean")
#<environment: namespace:base>
I thought about restricting the input to character variables such
as the
following
sumstats2 <- c("mean","sd")
Is there a way to change "mean" to the function mean?
You *can't* have a vector of functions, as far I know. The entries
of a vector must be (numeric, character, or logical) scalars.
You *can* have a *list* of functions; this might be the way you
want to go.
To ``change "mean" to the function mean'' --- set ?get.
