How to separate text answers in R?

I’m sure my doubt should be super simple to be solved so far I have not had any positive results in any of the tutorials I downloaded.

I am working on a df in R that there is a column that the answers were separated by ; that is, each participant could answer one more option (Example:Knowledge mapping, Automatic feedback, Artificial intelligence, Collaboration and co-authoring). I need to separate the answers so I can identify how many users answered each of the options without changing the number of participants/respondents.

Thank you very much, Priscilla.

    I’d do anything like resp <- lapply(df, strsplit, ","); table(unlist(resp)). But without seeing the data it is impossible to be sure. Edit the question with the departure of dput(head(df, 20)), please.

Use the function multi.split package questionr. To view the result, use multi.table.

v <- c("red,blue","green","red,green","blue,red")
multi.split(v, split.char = ",")
## Tabela de frequências
multi.table(multi.split(v, split.char = ","))

        n %multi
v.blue  2     50
v.red   3     75
v.green 2     50
