  • Hi. This is what I have to do " Using the rnorm function, create an object called sigma " I understand that rnorm is (N, Mean = 0,sd = 0) but then I am confused with sigma . – R Ranger Mar 24 '20 at 11:12

One approach to create an object is to call the generic of the class of object you want. For example, if you wanted to create a vector, you'd call vector

Sigma <- vector()

Other options include matrix, list and data.frame.
