two OutputsHello! I am Amelia from Auckland and work for a bank. I am new to R and I have started my venture with R just a couple of weeks back and this is my first mail to R-forum. I need following assistance
Suppose my R code generates following outputs as > X [[1]] [1] 40 [[2]] [1] 80 160 [[3]] [1] 160 80 400 > Y [[1]] [1] 10 [[2]] [1] 10 30 [[3]] [1] 5 18 20 and suppose Z = c(1, 2, 3) I need to perform the calculation where I will be multiplying corresponding terms of X and Y individually and multiplying their sum by Z and store these results in a dataframe. I.e. I need to calculate (40*10) * 1 # (first element of X + First element of Y) * Z[1] = 400 ((80*10)+(160*30)) * 2 # 2 row of X and 2nd row of Y = 11200 ((160*5)+(80*18)+(400*20)) * 3 # 3rd row of X and 3 row of Y and Z[3] = 30720 So the final output should be 400 11200 30720 One way of doing it is write R code for individual rows and arrive at the result e.g. ([[X]][1]*[[Y]][1])*1 will result in 400. However, I was just trying to know some smart way of doing it as there could be number of rows and writing code for each row will be a cumbersome job. So is there any better way to do it? Please guide me. I thank you in advance. Thanking all Amelia [[alternative HTML version deleted]]
