[R] R function to calculate number of data points of each level

I have a dataframe with two columns : 11600 238'4 12000 218'0 12200 209'0 12600 192'0 13000 176'4 14000 145'0 15000 119'0 16000 103'0 1800080'0 1900068'3 2 59'0 11600 208'1 12000 189'2 12200 180'3 There are repeatations in 1st column and I want to use this as
