longRun: Length of the longest run of a particular value in a numeric vector

Description

This function returns the lengh of the longest run of a particular numeric value in a numeric vector. A "run" is an uninterrupted sequence of the same number. Runs can be "wrapped" so that if the sequence starts and ends with the target value then it is considered as a consecutive run.

Usage

longRun(x, val, wrap = FALSE, na.rm = FALSE)

Value

Integer.

Arguments

x

Numeric vector.

val

Numeric. Value of the elements of x of which to calculate length of longest run.

wrap

Logical. If TRUE then runs can "wrap" from the end of x to the start of x if the first and last elements of x are equal to val.

na.rm

Logical. If TRUE then remove NAs first.
