R remove all characters after a slash in a dataframe

Question

I have some rows that need to have everything after a slash removed

x1\
myco\
myco\
myco/fungicide

is there a way I can do this?

Use `trimws("myco/fungicide", whitespace = "/.*")#[1] "myco"` — akrun, Jul 18 '22 at 19:32

i should have been more specific, there are many different words in this column, e.g.: herbicide/fungicide, insecticide/butane etc. — Adam France, Jul 18 '22 at 19:34

We may use trimws

df1$x1 <- trimws(df1$x1, whitespace = "/.*")
