Just to add to the answers already provided, here is another way of replacing the “.” or any other kind of punctation in column names by using a regex with the stringr package in the way like:

colnames(data) <- str_replace_all(colnames(data), "[:punct:]", " ")

For example try:

data <- data.frame(variable.x = 1:10, variable.y = 21:30, variable.z = "const")

colnames(data) <- str_replace_all(colnames(data), "[:punct:]", " ")

and

colnames(data)

will give you

[1] "variable x" "variable y" "variable z"
