coalesce.na: Replaces NA values

In kimisc: Kirill's miscellaneous functions

Description

This (vectorized) function returns the first non-NA argument, similar to the SQL function COALESCE. If a vector or matrix is passed as first argument, the remaining arguments are recycled to generate a vector/matrix of the same dimension, and coalescing is done element by element.

Usage

coalesce.na(x, ...)

Arguments

x	The first value to coalesce.
...	Other values to coalesce.

Value

A vector of the same length as x.

Examples

coalesce.na(NA, -1)
coalesce.na(5, 3)
coalesce.na(c(1,NA,NA), c(NA,2))
coalesce.na(matrix(c(NA, 1:3), nrow=2))
coalesce.na(NA)

Example output

[1] -1
[1] 5
[1]  1  2 NA
Warning message:
In coalesce.na(c(1, NA, NA), c(NA, 2)) :
  object length is not a multiple of first object length
     [,1] [,2]
[1,]   NA    2
[2,]    1    3
[1] NA
