matBack2OrgClass: Coerce a matrix (back) to 'class' of some other object

In NumDfr: Provide a performant alternative to data.frame wrt factors

Description

Coerce a matrix (back) to class of some other object

Usage

## S3 method for class 'numdfr'
matBack2OrgClass(objWithClass, mat, catCols, levelList, ord=rep(FALSE, ncol(mat)),
	colnms=NULL, verbosity=0)
## S3 method for class 'data.frame'
matBack2OrgClass(objWithClass, mat, catCols, levelList, ord=rep(FALSE, ncol(mat)),
	colnms=NULL, verbosity=0)

Arguments

objWithClass	object to dispatch class upon
mat	matrix to coerce (back) to format/class of objWithClass
catCols	indices of categorical columns
levelList	list of character vectors holding the labels for categorical columns
ord	logical vector indicating whether each column is an ordered factor
colnms	columnn names to use (if not the original ones - default is NULL)
verbosity	The higher this value, the more levels of progress and debug information is displayed (note: in R for Windows, turn off buffered output)

Value

object of the same class as objWithClass
