Hi, I have a list of regions and I would to merge the adiacent-similar regions into a bigger common region that include all of them:

print(selected_table, n = 30)
# A tibble: 271,961 × 4
   chr     start     end type 
   <chr>   <dbl>   <dbl> <chr>

23 chr1  4671654 4671956 dELS 
24 chr1  4706158 4706508 dELS 
25 chr1  4784168 4784518 dELS 
26 chr1  4785232 4785421 dELS 

What do you suggest, should I use Genomicranges::reduce() I am not sure what is the min.gaplength to set. I mean, there are some adiacent regions but maybe in some of them the distance between is bigger than in others. Any suggestions?

I would plot the distribution of the distance between adjacent intervals for further analysis.

Hi, could you explain how to do that?

plot the distance distribution and try to find a proper theresold to categorise distances into short and long and remove most short gaps.
