[R] Question on applying vectors to data.frames by row

# Newbie alert # I am wanting to multiply the rows in a dataframe by a vector. # However, the default behavior appears to be for the vector to be applied # column wise. For example: vct - 1:4 df - data.frame(c1 = 5:10, c2= 6:11, c3=7:12, c4=8:13) multTheTwo - vct * df multTheTwo # This results
