How to get the first element of a strsplit in R

I want to keep the first element of a string and store it in a variable.

In Python it would be word = 'AAAAAA.BBBB'.split('.')[0] but I can't find how to do it in R.

Thanks

We can use str_split

library(stringr)
str_split(string, fixed("."))[[1]][1]
#[1] "AAAAAA"

Or using trimws

trimws(string, whitespace = "\\..*")
#[1] "AAAAAA"

data

string <- 'AAAAAA.BBBB'

You could also use some simple regex:

sub('\\..*', '', 'AAAAAA.BBBB')
[1] "AAAAAA"

try this :

variable = unlist(strsplit('AAAAAA.BBBB', '\\.'))[1]

You can use

string <- 'AAAAAA.BBBB'
result <- strsplit(string, '.', fixed = TRUE)[[1]][1]
#[1] "AAAAAA"

You can also do this without splitting with regex removing everything after a period (.)

sub('\\..*', '', string)
