root.hist1D: ROOT 1D-Histogram

In xps: Processing and Analysis of Affymetrix Oligonucleotide Arrays including Exon Arrays, Whole Genome Arrays and Plate Arrays

Description

Creates a ROOT 1D-histogram for a ROOT tree.

Usage

root.hist1D(x, treename = character(0), logbase = "log2", type = "hist", option = "HIST", canvasname = "Histogram1D", save.as = "", w = 540, h = 540)

Arguments

x	object of class DataTreeSet or ExprTreeSet.
treename	name of tree, must be present in rootfile of object x.
logbase	usually “log2”, or “0”, determines if leaf data should be converted to log.
type	ROOT 1D-hist or density, i.e. “hist” or “density”.
option	ROOT 1D-hist option only, usually one of “HIST”, “B”, “C”, “E”.
canvasname	name of ROOT canvas
save.as	graphics type for saving canvas, one of “ps”, “eps”, “pdf”, “jpg”, “gif”, “png”, “tiff”
w	the width of the canvas in pixels.
h	the height of the canvas in pixels.

Details

Creates a ROOT 1D-histogram for tree treename present in rootfile.

By selecting menu “File->Save->canvasname.xxx” you can save the figure as e.g. *gif, *.jpg, *.pdf, *.ps or even as C++ macro.

Alternatively, you can save the plot by setting save.as. However, this will close the canvas immediately after opening it.

Note

Always select menu item “Quit ROOT” from menu “File” to close the ROOT canvas, otherwise you are in the CINT C/C++ interpreter from ROOT. To exit CINT, you need to type “.q”.

Examples

## Not run: 
## first, load ROOT scheme file and ROOT data file
scheme.test3 <- root.scheme(paste(path.package("xps"),"schemes/SchemeTest3.root",sep="/"))
data.test3 <- root.data(scheme.test3, paste(path.package("xps"),"rootdata/DataTest3_cel.root",sep="/"))

root.hist1D(data.test3, "TestA1.cel")
root.hist1D(data.test3, "TestA1.cel", type="density")

## End(Not run)
