r - Add data frames row wise with [d]plyr -


i have 2 data frames

df1 #     b # 1 10 20 # 2 11 21 # 3 12 22 # 4 13 23 # 5 14 24 # 6 15 25  df2 #   b # 1 4 8

i want following output:

df3 #     b # 1 14 28 # 2 15 29 # 3 16 30 # 4 17 31 # 5 18 32 # 6 19 33

i.e. add df2 each row of df1.

is there way desired output using plyr (mdplyr??) or dplyr?

i see no reason "dplyr" this. in base r do:

df1 + unclass(df2) #     b # 1 14 28 # 2 15 29 # 3 16 30 # 4 17 31 # 5 18 32 # 6 19 33

which same df1 + list(4, 8).
