Description

A function that returns a function with values for A, p and na.rm bound to the specified values. The function takes a single vector, x, as an argument. When the returned function is evaluated it returns TRUE if the proportion of values in x that are larger than A is at least p.

Usage

pOverA(p=0.05, A=100, na.rm=TRUE)

Arguments

`A`	The value to be exceeded.
`p`	The proportion that need to exceed `A` for `TRUE` to be returned.
`na.rm`	If `TRUE` then `NA`'s are removed.

Value

pOverA returns a function with bindings for A, p and na.rm. This function evaluates to TRUE if the proportion of values in x that are larger than A exceeds p.
