dropNA {plgraphics}

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.
