Remove all characters before a period in a string

Question

This keeps everything before a period:

gsub(\"\\\\..*\",\"\", data$column )

how to keep everything after the period?

Answer 1

require(stringr)

I run a course on Data Analysis and the students came up with this solution :

get_after_period <- function(my_vector) {    

        # Return a string vector without the characters
        # before a period (excluding the period)

        # my_vector, a string vector

        str_sub(my_vector, str_locate(my_vector, "\\.")[,1]+1) 

        }

Now, just call the function :

my_vector <-  c('foobar.barfoo', 'amazing.point')

get_after_period(my_vector)

[1] "barfoo" "point"
