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 in the vector getting cycled columnwise # c1 c2 c3 c4 # 1 5 18 7 24 # 2 12 28 16 36 # 3
