Function relabel changes the labels of a factor of any object
that has a names, labels, value.labels, or variable.labels attribute.
Function relabel4 is an (internal) generic which is called by relabel
to handle S4 objects.
## Default S3 method: relabel(x, ..., gsub = FALSE, fixed = TRUE, warn = TRUE) ## S3 method for class 'factor': relabel(x, ..., gsub = FALSE, fixed = TRUE, warn = TRUE) ## S4 method for signature 'item': relabel4(x, ...) # This is an internal method, see details. # Use relabel(x, ...) for 'item' objects
x |
An object with a names, labels, value.labels, or variable.labels attribute |
... |
A sequence of named arguments, all of type character |
gsub |
a logical value; if TRUE, gsub is used to change the
labels of the object. That is, instead of substituting whole labels, substrings of the
labels of the object can changed. |
fixed |
a logical value, passed to gsub. If TRUE,
substitutions are by fixed strings and not by regular expressions. |
warn |
a logical value; if TRUE, a warning is issues if a a change of labels was unsuccessful. |
This function changes the names or labels of x according to the
remaining arguments.
If gsub is FALSE, argument tags are the old
labels, the values are the new labels.
If gsub is TRUE, arguments are substrings of the labels
that are substituted by the argument values.
Function relabel is S3 generic. If its first argument is an S4 object,
it calls the (internal) relabel4 generic function.
The object x with new labels defined by the ... arguments.
