Hey everyone,

I'm working on developing a script to analyse my DNA methylation data using the minfi package, and keep running into this message whenever I try to run plotSex - can anyone make sense of it?

Cheers!


#code

plotSex(getSex(GRset, cutoff = -2))

#error message

If you take a look at the help page for plotSex, you can see what the inputs are supposed to be.

Usage:

     getSex(object = NULL, cutoff = -2)
     addSex(object, sex = NULL)
     plotSex(object, id = NULL)

Arguments:

  object: An object of class '[Genomic]MethylSet'.

And further down, you can see the outputs.

Value:

     For 'getSex', a 'DataFrame' with columns 'predictedSex' (a
     character with values 'M' and 'F'), 'xMed' and 'yMed', which are
     the chip-wide medians of measurements on the two sex chromosomes.

So plotSex expects as input a [Genomic]MethylSet, yet getSex returns a DataFrame. Obviously if you provide a DataFrame to a function that expects something entirely different you should not expect things to work. At the very bottom of the help page there is an example.

Examples:

     if(require(minfiData)) {
       GMsetEx <- mapToGenome(MsetEx)
       estSex <- getSex(GMsetEx)
       GMsetEx <- addSex(GMsetEx, sex = estSex)
     }

Which shows that you have to use addSex to add the output from getSex to your GenomicMethylSet, after which you can call plotSex on the updated GenomicMethylSet.
