GenomeGraphs (version 1.32.0)

DisplayPars: DisplayPars constructs objects of type DisplayPars which are used to effect the display of gdObjects

Description

DisplayPars takes any number of named arguments which will be used by the drawGD method of the gdObject. These arguments are analagous to both par and gp of the traditional and grid graphics systems respectively. Different functions support different graphical parameters - thus it is necessary to consult the documentation of the particular gdObject to determine which DisplayPars will be used.

Usage

DisplayPars(...)

Arguments

...

name value pairs

Value

Returns an object of type DisplayPars, generally this will be called during a call to the new function for a particular gdObject.

Details

It is not recommended to call new("DisplayPars", ...) directly; rather this function DisplayPars() should be called instead. If a gdObject has already been instantiated then the appropriate method for changing graphical parameters is: setPar.

Examples

minbase = 10000
maxbase = 15000
mart <- useMart("ensembl", dataset = "scerevisiae_gene_ensembl")
genesplus <- new("GeneRegion", start = minbase, end = maxbase, biomart = mart,
                strand = "+", chromosome = "I", dp = DisplayPars(color =
                "red"))
gaxis <- new("GenomeAxis", add53 = TRUE, add35 = TRUE)
genesminus <- new("GeneRegion", start = minbase, end = maxbase, biomart = mart,
                strand = "-", chromosome = "I", dp = DisplayPars(color =
                "purple", size = 2))
title <- new("Title", title = "genes in a region")
gdPlot(list(genesplus, gaxis, genesminus, title), minbase, maxbase)
