Arguments

chrom	chromsome of region to be plotted
params	an optional "bb_params" object space containing relevant function parameters
assembly	desired genome assembly
chromstart	start position
chromend	end position
fontcolors	a vector indicating the font colors for the plus strand and minus strand gene labels
strandcolors	a vector indicating the strand colors for the plus strand and minus strand
geneOrder	an ordered vector of gene names to prioritize labeling
geneHighlights	a two-column dataframe with gene names to highlight and their corresponding highlight color
geneBackground	if geneHighlights is given, background color for genes that are not highlighted
stroke	numerical value indicating the stroke width for gene body outlines
fontsize	the size of gene label text (in points)
strandLabels	A logical value indicating whether to include +/- strand labels
x	A numeric or unit object specifying x-location
y	A numeric or unit object specifying y-location
width	A numeric or unit object specifying width
height	A numeric or unit object specifying height
just	string or numeric vector specifying the justification of the viewport relative to its (x, y) location: "left", "right", "centre", "center", "bottom", "top"
default.units	A string indicating the default units to use if x, y, width, or height are only given as numerics
draw	A logical value indicating whether graphics output should be produced

Value

Function will plot a gene track and return a bb_genes object
