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

Another option:

df[unique(row(df[-1])[df[-1] == 1L]),]
#  company bond equity cash
#2       b    1      0    0
#4       d    0      1    0

df$company[unique(row(df[-1])[df[-1] == 1L])]
#[1] b d
#Levels: a b c d
