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.
