Thanks for this contribution. Since it's not required to know R or Bioconductor Packages for this project, I'm mostly looking for attention to detail in this contribution task.
Very neat work. Although the function doesn't work because sigs isn't defined, I can see how neatly you write code. Regarding your vignette, I think you could have unified the code block so that lines 17-18 could be with your examples. As it is, text in lines 20-28 are part of the code block. I had also requested as part of step 4 that you update the DESCRIPTION file.
