How to find TRUE value from a column in R

Question

I got dumb question, I have a column that has around millions of rows. I want to find if that column contains TRUE value (all the values in that column are either TRUE, FALSE, or NA. I am not very good in R so I don't want to use loop. Is there any way I can find whether this column has TRUE value or not?

Answer 1

To check if there are at least one TRUE in the column:

any(df$column_name)

Answer 2

We can use sum

sum(df$column_name) > 0
