Search values across all columns in R data frame

Question

Here\'s a sample data frame.

df = data.frame(company = c(\'a\', \'b\', \'c\', \'d\'),
                 bond = c(0.2, 1, 0.3, 0),
                 equity = c         


        

Answer 1

Use rowSums to check the logic data frame should work:

df[rowSums(df[-1] == 1.0) != 0, 'company']
[1] b d
Levels: a b c d
