CIMP markers in Infinium 450k Methylation Data (How To)

Question

[gaiusjaugustus]

I have methylation data for a group of patients done on the Infinium Methylation 450k platform. I want to look at the samples and determine if they are CIMP (CpG island methylator phenotype) positive or negative at the CIMP markers. I've run my data through the RnBeads pipeline in R, but am not sure how to use what I have to look at this information.

Any ideas or help would be appreciated.
