RCircos.Histogram.Plot: Plot Histogram for One Data Track

In RCircos: Circos 2D Track Plot

Plot Histogram for One Data Track

Description

Draw one track of histogram. RCircos core components and graphic device must be initialized before drawing.

Usage

RCircos.Histogram.Plot(hist.data=NULL, data.col=4,
    track.num=NULL, side=c("in", "out"), 
    min.value=NULL, max.value=NULL, inside.pos=NULL, 
    outside.pos=NULL, genomic.columns=3, is.sorted=TRUE)

Arguments

hist.data	A data frame with the first three columns as chromosome names, start position and end position of each data point followed by data values for one or more samples.
data.col	Non-negative integer, representing the ordinal number of the column in input data that contains the data to be plotted.
track.num	Non-negative integer, representing the ordinal number of the plot track where the histogram will be plotted.
side	Character vector, either "in" or "out", representing the position related to chromosome ideogram.
min.value	Numeric, minimum value for histogram
max.value	Numeric, maximum value for histogram
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.
genomic.columns	Non-negative integer, total number of columns for genomic position in each row. Must be either 3 or 2.
is.sorted	Logic, whether the data is sorted by chromosome names and start positions.
