Calculate gene-level methylation for a dataset containing CpGs from the Illumina 450k methylation array.
Gene-level methylation is calculated as the median beta-value among CpG islands in the gene promoter region.
Usage
gene.methylation(methy, print.progress = TRUE)
Arguments
- methy
methylation dataset where rownames give patient ids and columns use CpG ids
- print.progress
TRUE/FALSE to show progress bar
Examples
data(example.data);
### full example (may take a few mins to run)
#example.data.gene.methy <- gene.methylation(example.data);
### fast example
set.seed(123);
example.data <- example.data[,sample(1:ncol(example.data), 10)];
example.data.gene.methy <- gene.methylation(example.data);
