Rename columns

Description

This function renames columns of 'refMatr' using 2-column matrix (or data.frame) indicating old and new names (for replacement).

Usage

renameColumns(refMatr, newName, silent = FALSE, debug = FALSE, callFrom = NULL)

Arguments

refMatr	matrix (or data.frame) where column-names should be changed
newName	(matrix of character) giving correspondence of old to new names (number of lines must match number of columns of 'refMatr')
silent	(logical) suppres messages
debug	(logical) additional messages for debugging
callFrom	(character) allows easier tracking of messages produced

Value

This function returns a matrix (or data.frame) with renamed columns

Examples

ma <- matrix(1:8,ncol=4,dimnames=list(1:2,LETTERS[1:4]))
replBy1 <- cbind(new=c("dd","bb","z_"),old=c("D","B","zz"))
replBy2 <- matrix(c("D","B","zz","dd","bb","z_"),ncol=2)
replBy3 <- matrix(c("X","Y","zz","xx","yy","z_"),ncol=2)
renameColumns(ma,replBy1)
renameColumns(ma,replBy2)
renameColumns(ma,replBy3)
