In MESS: Miscellaneous Esoteric Statistical Scripts

Form row means conditional on number of non-missing

Description

Form row means for multiple vectors, numeric arrays (or data frames) conditional on the number of non-missing observations. NA is returned unless a minimum number of observations is observed.

Usage

conditional_rowMeans(..., minobs = 1L)

Arguments

...	a series of numeric vectors, arrays, or data frames that have can be combined with cbind
minobs	an integer stating the minimum number of non-NA observations necessary to compute the row mean. Defaults to 1.

Value

A numeric vector containing the row sums or NA if not enough non-NA observations are present

Examples

conditional_rowMeans(1:5, c(1:4, NA), c(1:3, NA, NA))
conditional_rowMeans(1:5, c(1:4, NA), c(1:3, NA, NA), minobs=0)
conditional_rowMeans(1:5, c(1:4, NA), c(1:3, NA, NA), minobs=2)
