R help - Mar 2008 - Error in Arules

Hi everyone,

 

This is my first posting and I am just starting to fumble my way thru R.
I have been working thru the Arules package, and I used to be able to
use the image function and I get the following message:

 

Error in image.default(basket2) : 'z' must be a matrix

 

I used to be able to plot the image.  I only started to get this error
when I tried to add x and y axis labels.  Any ideas?

 

Many thanks in advance,

 

- Brock

It would be helpful to show code that works, and code that doesn't.  But 
what the error message says is that someone (you?  the code you called?) 
called the image.default function with just one argument basket2, and 
it's not a matrix.
