Rename columns by pattern in R

Question

I would like to rename all my columns in a dataframe by a specific pattern.

My input:

Log.NE122  Log.NE244  Log.NE144
-0.33       0.98        1.0

My expected output:

 NE122  NE244  NE144
-0.33   0.98    1.0

Cheers.

Answer 1

You can use regular expressions to change the colnames() of an object. Here I'm replacing the Log. with nothing:

colnames(object) <- sub("Log\.", "", colnames(object))
