Return the middle portion of data similar to head and tail
middle(x, n = 10, evenly = TRUE, ...)input data that can be subset
numeric number of entries to return
logical indicating whether to return evenly spaced
entries along the full length of x. When evenly=FALSE only
the middle n entries are returned.
additional arguments are ignored.
This function is very simple, and is intended to mimic head()
and tail() to inspect data without looking at every value
