Remove everything from character after sign "+" in R

I have data in the following format:

2213000
6314931
2224100+ 2224200+ 2224900

I would like to remove everything after the first "+" sign for those characters in which "+" appears, while retaining the part of the character before the sign.

In other words, from the example above, I would need to have the following:

2213000
6314931
2224100

I have tried the following code,

my_data <- (gsub("\\+.*", "", mydata))

which returns a blank string, whereas I would need to retain the character before the first "+" sign.

Would greatly appreciate any help on how to fix this!

In my case `sub("\\+.*", "", c("2213000", "6314931", "2224100+ 2224200+ 2224900"))` gives the wanted result. – GKi Jul 07 '21 at 11:57
Is `mydata` a `vector`? – GKi Jul 07 '21 at 11:58

If `mydata` is dataframe you need to pass the column value. `mydata$col <- sub("\\+.*", "", mydata$col))` – Ronak Shah Jul 07 '21 at 12:13
Thank you both! Once I passed the column value I the issue was solved. Thank you so much again! – srocco Jul 07 '21 at 13:52
