freq.min: Minimum and maximum frequencies of a vector

Description Usage Arguments Details Value Author(s) See Also Examples

View source: R/frequency.R

Description

Minimum and maximum frequencies of a vector.

Usage

1
2
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.
