xi <- c(3:5,8,8,8,9:11,14)
yi <- c(5,4,5,4,7,8,8,9,10,10)
xiyi <- xi*yi
xisq <- xi^2
yisq <- yi^2
cSum <- rowSums(xi)
fg <- data.frame(xi, yi, xiyi, xisq, yisq)
View(fg)
Trying to get the total sum in every column but unable to get it. Can somebody help me to get the result? Above is the code. Thankyou in advance.
