R: Draw Heatmap for One Data Track

RCircos.Heatmap.Plot {RCircos} | R Documentation

## Draw Heatmap for One Data Track

### Description

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

### Usage

    RCircos.Heatmap.Plot(heatmap.data=NULL, data.col=NULL,
        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

`heatmap.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 set that contains the data to be plotted.
`track.num` | Non-negative Integer, representing the ordinal number of the plot track where the heatmap will be plotted.
`side` | Character vector, either "in" or "out", representing the position related to chromosome ideogram.
`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.
`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.
