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.

Somewhere you'd named an R object var, which is also the name of the function.

There's no way to access part of a function with $ so
var$contrib
is throwing the closure error, which is telling you that you can't
index a function.

[R] Issue with var command in stats package

[John, Larry]

Am using R version 3.2.4 in a fully updated version of Windows 7 and the most 
current versions of coorplot, FactoMineR and factoextra to support multiple 
correspondence analysis. However, today, a line of code that worked just fine 
on one set of data produced an error message on a different set of data.

Specifically, when I ran:

corrplot(var$contrib, is.corr = FALSE)

I received the following message:

> corrplot(var$contrib, is.corr = FALSE)
Error in var$contrib : object of type 'closure' is not subsettable

Can you please tell me what this error message means and roughly what I might 
need to do to correct it? If necessary, I can provide the original data files.

Many thanks for your kind help.

Very Respectfully,
