How to add multiple rows to data frame in R

Answer 1

df = data.frame(a = c(1, 3, 9, 0),
                b = c(12, 98, 90, 20),
                c = c(2, 4, 6, 8),
                row.names = c('o', 'p', 'q', 'r'))

print(df)

df2 = data.frame(a = c(456, 100),
                 b = c(390, 300),
                 c = c(155, 999),
                 row.names = c('x', 'y'))

print(df2)

df = rbind(df, df2)

print(df)
