Usage

middle(x, n = 10, evenly = TRUE, ...)

Arguments

x

input data that can be subset

n

numeric number of entries to return

evenly

logical indicating whether to return evenly spaced entries along the full length of x. When evenly=FALSE only the middle n entries are returned.

...

Value

an object of class equivalent to x.

Details
