Since there is apparently not an object in your workspace named `var`, the
interpreter is instead finding the function named `var` (which delivers the
variance of a vector) and then is trying to apply the `$`-function to it ....
but there is no `$`-method for functions.

I doubt that the error is in your data. You need to find the section of code
that was supposed to be creating an object named `var` and hopefully you now
understand why that naming convention was a bad idea. Rewrite that section of
code to use objects having more meaningful names, which will result in errors
that are more helpful to you in the future.
