strsplit() Syntax:
Syntax: strsplit(string, split, fixed)
Parameters:
- string: Input vector or string.
- split: It is a character of string to being split.

Return: Returns the list of words or sentences after split.
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 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 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 "-".
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"
