How to find the sum of numbers stored in character vector separated with a special character in R?
To find the sum of numbers stored in character vector separated with a special character in R, we can follow the below steps −
- First of all, create a vector having numbers stored in character vector separated with a special character.
- Then, use sapply and strsplit function to find the sum of numbers.
Example1
Create a vector with numbers stored in character vector separated with hyphen −
> x1<-sample(c("10-4-5-19-10","11-2-15-19-10","21-21-50-90-10","15-25-52-91-
10","17-27-55-91-100","13-12-75-29-18","14-29-57-92-13"),80,replace=TRUE)
> x1On executing, the above script generates the below output(this output will vary on your system due to randomization) −
[1] "11-2-15-19-10" "11-2-15-19-10" "13-12-75-29-18" "15-25-52-91-10" [5] "15-25-52-91-10" "17-27-55-91-100" "13-12-75-29-18" "15-25-52-91-10" [9] "13-12-75-29-18" "10-4-5-19-10" "17-27-55-91-100" "14-29-57-92-13" [13] "15-25-52-91-10" "21-21-50-90-10" "15-25-52-91-10" "15-25-52-91-10" [17] "13-12-75-29-18" "15-25-52-91-10" "17-27-55-91-100" "10-4-5-19-10" [21] "15-25-52-91-10" "17-27-55-91-100" "15-25-52-91-10" "21-21-50-90-10" [25] "10-4-5-19-10" "10-4-5-19-10" "10-4-5-19-10" "15-25-52-91-10" [29] "11-2-15-19-10" "10-4-5-19-10" "17-27-55-91-100" "14-29-57-92-13" [33] "17-27-55-91-100" "13-12-75-29-18" "11-2-15-19-10" "14-29-57-92-13" [37] "17-27-55-91-100" "17-27-55-91-100" "11-2-15-19-10" "21-21-50-90-10" [41] "13-12-75-29-18" "15-25-52-91-10" "10-4-5-19-10" "14-29-57-92-13" [45] "15-25-52-91-10" "13-12-75-29-18" "11-2-15-19-10" "11-2-15-19-10" [49] "11-2-15-19-10" "13-12-75-29-18" "14-29-57-92-13" "21-21-50-90-10" [53] "11-2-15-19-10" "11-2-15-19-10" "21-21-50-90-10" "14-29-57-92-13" [57] "21-21-50-90-10" "21-21-50-90-10" "11-2-15-19-10" "15-25-52-91-10" [61] "10-4-5-19-10" "11-2-15-19-10" "11-2-15-19-10" "13-12-75-29-18" [65] "21-21-50-90-10" "11-2-15-19-10" "17-27-55-91-100" "21-21-50-90-10" [69] "15-25-52-91-10" "21-21-50-90-10" "15-25-52-91-10" "21-21-50-90-10" [73] "15-25-52-91-10" "15-25-52-91-10" "21-21-50-90-10" "10-4-5-19-10" [77] "13-12-75-29-18" "11-2-15-19-10" "11-2-15-19-10" "14-29-57-92-13"
