Hello,

I'm working on illumina methylation array data. Focusing on the methylation pattern at 11p15.5, a imprinted region, I plan to use "methyAnalysis" to draw a heatmap by chromosome location.

Before actually analysing my data, I first tried the example codes and got the following error:

Error: Expectation Failed

Because it's just copy and paste of example code, I don't figure out what causes this error.

Can anyone help me with this error?

Thanks,

Tom
