freq.min: Minimum and maximum frequencies of a vector

In Rfast: A Collection of Efficient and Extremely Fast R Functions

Minimum and maximum frequencies of a vector

Description

Minimum and maximum frequencies of a vector.

Usage

freq.min(x,na.rm = FALSE)
freq.max(x,na.rm = FALSE)

Arguments

x	A numerical/integer vector with data but without NAs.
na.rm	TRUE or FAlSE for remove NAs if exists.

Details

Those functions are the same with max(table(x) or min(table(x)) but with one exception. freq.min and freq.max will return also which value has the minimum/maximum frequency. More Efficient than max(table(x) or min(table(x)).

Value

A vector with 2 values, the value with minimum/maximum frequency and the frequency.

Examples

x <- rnorm(100)
f1 <- freq.min(x) 
f2 <- freq.max(x) 
# f1r <- min(table(x))
# f2r <- max(table(x))
# f1[2]==f1r ## the frequencies are the same
# f2[2]==f2r ## the frequencies are the same
