Computes the percentage of values in a vector less than or greater than (and equal to) a user-supplied value.

perc(
  x,
  val,
  dir = c("geq", "gt", "leq", "lt"),
  na.rm = TRUE,
  digits = getOption("digits")
)

`x`	A numeric vector.
`val`	A single numeric value.
`dir`	A string that indicates whether the percentage is for values in `x` that are “greater than and equal” `"geq"`, “greater than” `"gt"`, “less than and equal” `"leq"`, “less than” `"lt"` the value in `val`.
`na.rm`	A logical that indicates whether `NA` values should be removed (DEFAULT) from `x` or not.
`digits`	A single numeric that indicates the number of decimals the percentage should be rounded to.

This function is most useful when used with an apply-type of function.

A single numeric that is the percentage of values in x that meet the criterion in dir relative to val.

## vector of values
( tmp <- c(1:8,NA,NA) )

## percentages excluding NA values
perc(tmp,5)
perc(tmp,5,"gt")
perc(tmp,5,"leq")
perc(tmp,5,"lt")

## percentages including NA values
perc(tmp,5,na.rm=FALSE)
perc(tmp,5,"gt",na.rm=FALSE)
perc(tmp,5,"leq",na.rm=FALSE)
perc(tmp,5,"lt",na.rm=FALSE)
