Description

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

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

Arguments

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

Examples

## 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)
