Extract {CorrBin}

R Documentation

Extract from a CBData or CMData object

Description

The extracting syntax works as for [.data.frame, and in general the returned object is not a CBData or CMData object. However if the columns are not modified, then the result is still a CBData or CMData object with appropriate attributes preserved, and the unused levels of treatment groups dropped.

Usage

## S3 method for class 'CBData'
x[i, j, drop]

## S3 method for class 'CMData'
x[i, j, drop]

Arguments

x	CMData object.
i	numeric, row index of extracted values
j	numeric, column index of extracted values
drop	logical. If TRUE the result is coerced to the lowest possible dimension. The default is the same as for [.data.frame: to drop if only one column is left, but not to drop if only one row is left.

Value

a CBData or CMData object
