Listers,
I have a question regarding correlation matrices. It is fairly straight
forward to build a correlation matrix of an entire data frame. I simply use
the command cor(MyDataFrame). However, what I would like to do is construct
a smaller correlation matrix using just three of the variable out of my data
set.
When I run this:
cor(MyDataFrame$variable1, MyDataFrame$variable2,MyDataFrame$variable3) I
get an error.
Is there a way to do this through a built in function or is this something I
have to construct manually?
Thanks
