Tools for Working With Zeros

Description

• remove_zero() remove rows/columns that contain zeros.

• replace_zero() replaces zeros.

Usage

remove_zero(x, ...)

replace_zero(x, ...)

## S4 method for signature 'ANY'
remove_zero(x, margin = 1, all = FALSE)

## S4 method for signature 'matrix'
replace_zero(x, value)

## S4 method for signature 'data.frame'
replace_zero(x, value)

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.
value	A possible replacement value.

## Create a data matrix
X <- matrix(sample(1:10, 25, TRUE), nrow = 5, ncol = 5)

## Add zero
k <- sample(1:25, 3, FALSE)
X[k] <- 0
X

## Remove rows with zero
remove_zero(X, margin = 1)

## Replace zero
