I have only beta values available to me in a matrix from 450k array data. I am trying to load the values into minfi as a GenomicRatioSet but keep getting the same error:
> ratioSet <- ratioConvert(betaM, what="beta", keepCN=TRUE)
> Error in (function (classes, fdef, mtable) : unable to find an inherited method for function ‘ratioConvert’ for signature ‘"matrix"’
I tried to make the matrix a dataframe instead and I get the same error except with the word "matrix" replaced with "data.frame".
I would like to use the getSex check in minfi and this requires loading in the GenomicRatioSet.
Any help you can provide would be greatly appreciated.
