For anyone with this error,

Make sure that the loh.name.mapping dataframe has the following properties
loh.name is the names of samples as they are from the BAF file—i.e. ie sample.baf, sample.snp —this might be the case if you used a different suffix

sample.name is the names of samples as they are in the count dataframe—the column names.

Otherwise your R will crash.
