Arguments

zoom.data	A data frame containing genomic positions, gene names, and plot values for zoom-in genes/rows.
zoom.range	Character vecter, chromosome name, start and end positions of a genomic interval to be zoomed in.
data.col	Non-negative integer/vector, which column(s) is plot data values.
track.num	Non-negative integer, which track will be plotted.
zoom.pos	Non-negative numeric vector, the index of RCircos plot position.
min.value	Numeric, minimum value for heatmap scale.
max.value	Numeric, maximum value for heatmap scale.
inside.pos	Non-negative numeric, inside position (relative to the centre of plot area) of the track.
outside.pos	Non-negative numeric, outside position (relative to the centre of plot area) of the track.
name.col	Non-negative integer, which column is for labels.
genomic.cols	Non-negative integer, total number of columns for genomic position information (chromosome, start and/or end position).
fill.color	Character vector for name of a color to fill the polygon.
border.col	Character vector for name of a color to draw the polygon border.
area.color	Character vector for name of a color to fill the area.
text.size	Non-negative numeric, character size for text plot.
line.width	Non-negative numeric, width of lines.
point.type	Non-negative integer, type of character for point plot (Default 19).
plot.type	Character vector, either "mountain", "curtain", or "ban", types of area plot.
by.fold	Zero or a positive float number, if it is greater than zero, any data point with a value greater than or equal to the by.fold will be plot as red color and data points with values less or equal to the negative by.fold will be plot as blue colr. Otherwise, black color is used.
with.size	Logic. If TRUE, the point size will match to the data value in scatter/point plot.
with.height	Logic. If TURE, point location will match to the data value in scatter/point plot.
point.scale	Non-negative numeric, more scale to add for scatter/point size in scatter/point plot.
outline	Logic. If TURE, outline will be drawn for zoomed area.
zoom.info	Character vector contains chromosome name, start and end position.
tick.interval	Non-negative integer, length of genomic interval in million base pairs.
layers	Non-negative integer, number of subtrack in the data track.
