Question

 I have this dataframe 

      CC.Number       Date Time Accident.Type              Location.1
    1 12T008826 07/01/2012 1630            PD  (39.26699, -76.560642)
    2          


        

Answer 1

We can use extract from tidyr by capturing as two groups with only the numeric elements with dots and discard the rest in 'Location.1'

library(tidyr)
df1 %>% 
  extract(Location.1, into = c('alt', 'lng'), "\\(([0-9.]+),\\s+(-*[0-9.]+).")
# CC.Number       Date Time Accident.Type       alt        lng
#1 12T008826 07/01/2012 1630            PD  39.26699 -76.560642
#2 12L005385 07/02/2012 1229            PD 39.000549 -76.399312
#3 12L005388 07/02/2012 1229            PD  39.00058 -76.399267
#4 12T008851 07/02/2012  445            PI  39.26367  -76.56648
#5 12T008858 07/02/2012  802            PD 39.240862 -76.599017
#6 12T008860 07/02/2012  832            PD  39.27022  -76.63926
