How to remove dot and number at the end of the string in an R vector?
To remove dot and number at the end of the string, we can use gsub function. It will search for the pattern of dot and number at the end of the string in the vector then removal of the pattern can be done by using double quotes without space. After that the vector will be passed as shown in the below examples.
Example1
x1<−c("weds.12","red.1","the.3")
x1<−gsub("\\.[0-9]*$","",x1)
x1Output
[1] "weds" "red" "the"
Example2
sample(c("india.32","russia.14","croatia.17","indonesia.54","japan.05"),80,replace=TRUE)
x2Output
[1] "japan.05" "russia.14" "japan.05" "india.32" "japan.05" [6] "japan.05" "japan.05" "india.32" "croatia.17" "croatia.17" [11] "indonesia.54" "croatia.17" "indonesia.54" "russia.14" "croatia.17" [16] "russia.14" "india.32" "russia.14" "russia.14" "russia.14" [21] "japan.05" "croatia.17" "croatia.17" "russia.14" "russia.14" [26] "croatia.17" "japan.05" "russia.14" "japan.05" "indonesia.54" [31] "indonesia.54" "croatia.17" "croatia.17" "india.32" "russia.14" [36] "russia.14" "russia.14" "russia.14" "croatia.17" "indonesia.54" [41] "india.32" "india.32" "india.32" "russia.14" "croatia.17" [46] "russia.14" "croatia.17" "japan.05" "india.32" "india.32" [51] "indonesia.54" "russia.14" "indonesia.54" "croatia.17" "croatia.17" [56] "croatia.17" "croatia.17" "indonesia.54" "india.32" "croatia.17" [61] "india.32" "indonesia.54" "india.32" "russia.14" "india.32" [66] "russia.14" "russia.14" "indonesia.54" "india.32" "croatia.17" [71] "india.32" "japan.05" "croatia.17" "croatia.17" "russia.14" [76] "india.32" "russia.14" "russia.14" "indonesia.54" "croatia.17"
