## plots gene structure or transcript structures

### Description

plots gene structure or transcript structures

### Usage

    plotGenes(geneinfo = NULL, chrom = NULL, chromstart = NULL,
      chromend = NULL, col = SushiColors(2)(2)[1], bheight = 0.3,
      lheight = 0.3, bentline = TRUE, packrow = TRUE, maxrows = 10000,
      colorby = NULL, colorbyrange = NULL,
      colorbycol = colorRampPalette(c("blue", "red")), types = "exon",
      plotgenetype = "box", arrowlength = 0.005, wigglefactor = 0.05,
      labeltext = TRUE, labeloffset = 0.4, fontsize = 0.7, fonttype = 2,
      labelat = "middle", ...)

### Arguments

`geneinfo` | gene info stored in a bed-like format. If NULL it will look up genes in the region using biomart (with biomart="ensembl" and dataset="hsapiens_gene_ensembl"). See also `useMart`
`chrom` | chromosome of region to be plotted
`chromstart` | start position
`chromend` | end position
`col` | single value or vector specifying colors of gene structures
`bheight` | the height of the boxes drawn for exons
`lheight` | the height of the bent line is bent is set to TRUE
`bentline` | TRUE/FALSE indicating whether lines between exons should be bent
`packrow` | TRUE / FALSE indicating whether genes should be packed or whether each gene should be plotted on its own row
`maxrows` | The maximum number of rows to plot on the y-axis
`colorby` | vector to scale colors by
`colorbyrange` | the range of values to apply the color scale to. Values outside that range will be set to the limits of the range.
`colorbycol` | palette to apply color scale to (only valid when colorby is not NULL)
`types` | single value or vector specifying types of elements (acceptable values are 'exon','utr')
`plotgenetype` | String specifying whether the genes should resemble a 'box' or a 'arrow'
`arrowlength` | value (between 0 and 1) specifying the length of the tail of each arrow as a fraction of the total plot width (only valid when plotgenetype is set to "arrow")
`wigglefactor` | the fraction of the plot to leave blank on either side of each element to avoid overcrowding.
`labeltext` | TRUE/FALSE indicating whether genes should be labeled
`labeloffset` | value (between 0 and 1) specifying the vertical offset of gene labels
`fontsize` | font size of gene labels
`fonttype` | font type of gene labels
`labelat` | postion along gene to place labels (acceptable values are "middle","start",and "end")
`...` | values to be passed to `plot`

### Examples

    data(Sushi_genes.bed)

    chrom            = "chr15"
    chromstart       = 72998000
    chromend         = 73020000
    chrom_biomart    = 15

    plotGenes(Sushi_genes.bed,chrom_biomart,chromstart,chromend ,types=Sushi_genes.bed$type,
         maxrows=1,height=0.5,plotgenetype="arrow",bentline=FALSE,col="blue",
         labeloffset=1,fontsize=1.2)

    labelgenome( chrom, chromstart,chromend,side=1,scipen=20,n=3,scale="Mb",line=.18,chromline=.5,scaleline=0.5)
