CoverageView error (bug?)

Hi, I would like to use the CoverageView for get the coverage reads of many regions in many samples. I am using the function cov.matrix. 




Since I have many samples and I would like to show the data with an heatmap where each row is a genomic region, each column is a sample and each cell value is the coverage. Therefore, for obtain a single coverage value, I need to set the parameter no_windows=1 instead of, say, 100. In other words, I don't want to slice my genomic region into two or more bins.

However, in this particular case (no_windows=1, offset=0), I get this error:

cov.matrix(covObj, coordfile=my_bed_file, no_windows=1, offset=0, normalization="rpm"); 

[INFO] A coverage matrix composed of average coverages will be generated.

[INFO] processing coords:chr19 1000437 1009723
Error in seq.default(from = (0.9 + bin_width), to = ceil, by = bin_width) : 
  wrong sign in 'by' argument

I think that the code is not capable of manage this particular case where the user don't want to slice regions in bins.

Can anyone help me? Thanks very much!!
