[R] length of 'dimnames' [2] not equal to array extent- For Correlation Plot

[Sarah Goslee]

I'm assuming you are using the corrplot package.

If so, your data object does need to be a matrix, not a data frame.
Since it's already a data frame, your line of code:

as.matrix(as.data.frame(CR1))

doesn't need the as.data.frame function, but more importantly, you
didn't assign the result to anything: as.matrix() does not work in
place.

CR1 <- as.matrix(CR1)

Now try.

If that doesn't work, then provide a reproducible example so we can
offer further advice.
