dropNA: drop or replace NA values

In plgraphics: User Oriented Plotting Functions

drop or replace NA values

Description

dropNA returns the vector 'x', without elements that are NA or NaN or, if 'inf' is TRUE, equal to Inf or -Inf. replaceNA replaces these values by values from the second argument

Usage

dropNA(x, inf = TRUE)
replaceNA(x, na, inf = TRUE)

Arguments

x	vector from which the non-real values should be dropped or replaced
na	replacement or vector from which the replacing values are taken.
inf	logical: should 'Inf' and '-Inf' be considered "non-real"?

Value

For dropNA: Vector containing the 'real' values of 'x' only
For replaceNA: Vector with 'non-real' values replaced by the respective elements of na.

Note

The differences to 'na.omit(x)' are: 'Inf' and '-Inf' are also dropped, unless 'inf==FALSE'.\ no attribute 'na.action' is appended.
