Rename columns
renameColumns renames columns of 'refMatr' using 2-column matrix (or data.frame) indicating old and new names (for replacement).
renameColumns(refMatr, newName, silent = FALSE, callFrom = NULL)
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 |
callFrom |
(character) allows easier tracking of message(s) produced |
