Renaming levels of a factor - Cookbook for R # Rename by name: change "beta" to "two" levels(x) [levels(x)=="beta"] <- "two" # You can also rename by position, but this is a bit dangerous if your data # can change in the future. If there is a change in the number or positions of # factor levels, then this can result in wrong data.

FACTOR in R [CREATE, CHANGE LABELS and CONVERT data] On the one hand, the labels argument allows you to modify the factor levels names. Hence, the labels argument it is related to output.

If no labels are specified labels (data) returns the column names of the data frame. Using abbreviate = TRUE, all labels are abbreviated to (at least) 4 characters such that they are unique. Other minimal lengths can specified by setting minlength (see examples below). Variable and value labels support in base R and other packages Variable label is human readable description of the variable. R supports rather long variable names and these names can contain even spaces and punctuation but short variables names make coding easier. Variable label can give a nice, long description of variable. With this description it is easier to remember what those variable names refer to.

You can use the factor function to create your own value labels. # variable v1 is coded 1, 2 or 3 # we want to attach value labels 1=red, 2=blue, 3=green mydata$v1 <- factor (mydata$v1, levels = c (1,2,3), labels = c ("red", "blue", "green"))
