methylSeekR error about missing value

Question

[897776177]

I have meet an error with the software MethylSeekR. When i try to use the readMethylome function to read the data, it posts such error:

Error in validObject(.Object) : invalid class “GRanges” object: 'seqnames(x)' contains missing values

However when i try to use the sumis.na(filename)), the result is 0, that is sumis.na(filename)) = 0 .

I am not sure the reason why it gives me such message. Would you please give me some suggestion??

best wishes

Can you show the result of head(filename) -- my guess at this point is that filename is just a character string (pointing to the file) and not the actual file content.
