Assigning colnames() to specific column of a data frame

Question

I have a question about the colnames function in the base package

Let\'s say you have a data.frame, as follows:

df <- data.frame(var         


        

Answer 1

Because you should be doing this:

> colnames(df)[1] <- "test"
> colnames(df)[1]
[1] "test"

The colnames function returns a character vector that can be altered.
