## Lolliplots

### Description

Plot variants and somatic mutations

### Usage

    lolliplot(SNP.gr, features = NULL, ranges = NULL, type = "circle",
      newpage = TRUE, ylab = TRUE, ylab.gp = gpar(col = "black"),
      yaxis = TRUE, yaxis.gp = gpar(col = "black"), xaxis = TRUE,
      xaxis.gp = gpar(col = "black"), legend = NULL, cex = 1,
      dashline.col = "gray80", jitter = c("node", "label"),
      rescale = FALSE, ...)

### Arguments

`SNP.gr` | A object of GRanges, GRangesList or a list of GRanges. All the width of GRanges must be 1.
`features` | A object of GRanges, GRangesList or a list of GRanges. The metadata 'featureLayerID' are used for drawing features in different layers. See details in vignette.
`ranges` | A object of GRanges or GRangesList.
`type` | character. Could be circle, pie, pin, pie.stack or flag.
`newpage` | Plot in the new page or not.
`ylab` | Plot ylab or not. If it is a character vector, the vector will be used as ylab.
`ylab.gp, xaxis.gp, yaxis.gp` | An object of class gpar for ylab, xaxis or yaxis.
`yaxis` | Plot yaxis or not.
`xaxis` | Plot xaxis or not. If it is a numeric vector with length greater than 1, the vector will be used as the points at which tick-marks are to be drawn. And the names of the vector will be used to as labels to be placed at the tick points if it has names.
`legend` | If it is a list with named color vectors, a legend will be added.
`cex` | cex will control the size of circle.
`dashline.col` | color for the dashed line.
`jitter` | jitter the position of nodes or labels.
`rescale` | logical(1) or a dataframe with rescale from and to. Recalse the x-axis or not. if dataframe is used, colnames must be from.start, from.end, to.start, to.end.
`...` | not used.

### Details

In SNP.gr and features, metadata of the GRanges object will be used to control the color, fill, border, height, cex, dashline.col, data source of pie if the type is pie. And also the controls for labels by name the metadata start as label.parameter.<properties> such as label.parameter.rot, label.parameter.gp. The parameter is used for grid.text. The metadata 'featureLayerID' for features are used for drawing features in different layers. The metadata 'SNPsideID' for SNP.gr are used for determining the side of lollipops. And the 'SNPsideID' could only be 'top' or 'bottom'.

### Examples

    SNP <- c(10, 100, 105, 108, 400, 410, 420, 600, 700, 805, 840, 1400, 1402)
    x <- sample.int(100, length(SNP))
    SNP.gr <- GRanges("chr1", IRanges(SNP, width=1, names=paste0("snp", SNP)),
                      value1=x, value2=100-x)
    SNP.gr$color <- rep(list(c("red", 'blue')), length(SNP))
    SNP.gr$border <- sample.int(7, length(SNP), replace=TRUE)
    features <- GRanges("chr1", IRanges(c(1, 501, 1001),
                                        width=c(120, 500, 405),
                                        names=paste0("block", 1:3)),
                        color="black",
                        fill=c("#FF8833", "#51C6E6", "#DFA32D"),
                        height=c(0.1, 0.05, 0.08),
                        label.parameter.rot=45)
    lolliplot(SNP.gr, features, type="pie")
