Splitting Strings in R language Example

Example 1: Using strsplit() function with delimiter

Here, we are using strsplit() along with delimiter, delimiter is a character of an existing string to being removed from the string and display out.

R `

R program to split a string

Given String

gfg < - "Geeks For Geeks"

Using strsplit() method

answer < - strsplit(gfg, " ")

print(answer)

`

Output:

[1] "Geeks" "For" "Geeks"

Example 2: strsplit() function with Regular Expression delimiter

Here, we are using regular expressions in delimiter to split the string.

R `

R program to split a string

Given String

gfg <- "Geeks9For2Geeks"

Using strsplit() method

answer <- strsplit(gfg, split = "[0-9]+")

print(answer)

`

Output:

[1] "Geeks" "For" "Geeks"

Example 3: Splitting the dates using strsplit() function in R

We can also manipulate with date using strsplit(), only we need to understand the date formatting, for example in this date( 2-07-2020) following the same pattern (-), so we can remove them using delimiter along with "-".

R `

string_date<-c("2-07-2020","5-07-2020","6-07-2020", "7-07-2020","8-07-2020") result<-strsplit(string_date,split = "-") print(result)

`

Output:

[[1]] [1] "2" "07" "2020"

[[2]] [1] "5" "07" "2020"

[[3]] [1] "6" "07" "2020"

[[4]] [1] "7" "07" "2020"

[[5]] [1] "8" "07" "2020"
