root.hist3D: ROOT 3D-Histogram

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

Description

Creates a ROOT 3D-histogram for a ROOT tree.

Usage

root.hist3D(x, treename1 = character(0), treename2 = character(0), treename3 = character(0), logbase = "log2", option = "HIST", canvasname = "Histogram3D", save.as = "", w = 540, h = 540)

Arguments

x	object of class DataTreeSet or ExprTreeSet.
treename1	name of first tree, must be present in rootfile of object x.
treename2	name of second tree, must be present in rootfile of object x.
treename3	name of third tree, must be present in rootfile of object x.
logbase	usually “log2”, or “0”, determines if leaf data should be converted to log.
option	ROOT hist TH3 option, usually one of “HIST”, “SCAT”, “BOX”.
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 3D-histogram for trees treename1, treename2 and treename3 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.

By moving the mouse into the middle of the canvas, the cursor changes and you can rotate the 3D-histogram. By selecting menu “View->View With->OpenGL” the OpenGL viewer opens, where you can rotate the 3D-histogram interactively.

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.hist3D(data.test3, "TestA1.cel", "TestB2.cel", "TestB1.cel", option="BOX")

## End(Not run)
