Rename by Name in R Sometimes you would be.
Rename Column using colnames () colnames () is the method available in R base which is used to rename.

As a data frame is actually a list containing same-length vectors under the hood, its possible to name and rename data frames just as you did with lists. rename() can take any number of arguments, where each new column name is assigned to replace an old column name in the format newcolumnname oldcolumnname. These two options work, though seems very fragile to rename in this way It only works if you have exactly one column that meets the condition, i.e. Quick Examples of Rename Column Following are quick examples to rename columns/variables of the R data frame.
