How can data labels be edited in R programming language?

In R language, we can use the labels() function to change data labels.

Suppose there is a data frame named data, which contains a variable named “column”, and this code can be used to modify its data label:

# 修改数据标签
labels(data$column) <- c("label1", "label2", "label3", ...)

The new labels, c(“label1”, “label2”, “label3”, …), need to be specified in the order of the data. If there are many data labels, alternative methods can also be used for representation.

It is important to note that changing the data labels only modifies the display labels, not the actual data itself.
