Rename a column in a dataset

If newName already exists in data and would be overwritten with a different source column, this is treated as a hard error so that user data is never silently clobbered.

Usage

.renameOrOverwrite(data, newName, oldName)

Arguments

data

The dataset to modify

newName, oldName

The new and old column names

Value

data with data[[newName]] <- data[[charOld]]

Examples

if (FALSE) { # \dontrun{
.renameOrOverwrite(data.frame(A=1), newName="B", oldName="A")
} # }
