Hi all! I am using the package chromPlot but I'm having some problems with the legend placement. According to chromPlot manual:

(...)two options: 1. setting the legChrom argument to an arbitrary chromosome name 2. setting the legChrom to NA to omit plotting a legend.

First showing the structure of my data:

> head(data)
  Chrom    Start      End         Group
1 chr2L  1573892  1573953  SimpleRepeat
2 chr2L  1589915  1589962 LowComplexity
3 chr2L  1596249  1596279  SimpleRepeat
4 chr2L 14803935 14804210           LTR
5  chrX    50787    55026          LINE
6  chrX    57732    63810          LINE

Here's my code:

chromPlot(gaps = gap_file, bands = data, title = "My title", legChrom = NA)

Here's my sessioninfo()

And finally I attach the plot produced: enter image description here

Basically, I would like to either move the legend to the bottom of Y chromosome (ie: legChrom = "Y") or eliminate the legend (legChrom = NA) and add it after with legend(). However none of these options work and the legend lies in the same position always (possible bug?)

Thanks in advance for your help!
