Remove Rows/Columns with Missing Values

Description

Removes rows/columns that contain missing values.

Usage

remove_NA(x, ...)

## S4 method for signature 'ANY'
remove_NA(x, margin = 1, all = FALSE, verbose = getOption("arkhe.verbose"))

Arguments

x	An R object (should be a matrix or a data.frame).
...	Currently not used.
margin	A length-one numeric vector giving the subscripts which the function will be applied over (1 indicates rows, 2 indicates columns).
all	A logical scalar. If TRUE, only the rows/columns whose values all meet the condition defined by f are considered. If FALSE (the default), only rows/columns where at least one value validates the condition defined by f are considered.
