epGraphs function

epGraphs: ExPosition plotting function

ExPosition plotting function which is an interface to prettyGraphs.

epGraphs(res, x_axis = 1, y_axis = 2, epPlotInfo = NULL, DESIGN=NULL,
fi.col = NULL, fi.pch = NULL, fj.col = NULL, fj.pch = NULL, col.offset =
NULL, constraints = NULL, xlab = NULL, ylab = NULL, main = NULL,
contributionPlots = TRUE, correlationPlotter = TRUE, graphs = TRUE)

Arguments

• res: results from ExPosition
• x_axis: which component should be on the x axis?
• y_axis: which component should be on the y axis?
• epPlotInfo: A list ($Plotting.Data) from epGraphs or ExPosition.
• DESIGN: A design matrix to apply colors (by pallete selection) to row items
• fi.col: A matrix of colors for the row items. If NULL, colors will be selected.
• fi.pch: A matrix of pch values for the row items. If NULL, pch values are all 21.
• fj.col: A matrix of colors for the column items. If NULL, colors will be selected.
• fj.pch: A matrix of pch values for the column items. If NULL, pch values are all 21.
• col.offset: A numeric offset value. Is passed to createColorVectorsByDesign.
• constraints: Plot constraints as returned from prettyPlot. If NULL, constraints are selected.
• xlab: x axis label
• ylab: y axis label
• main: main label for the graph window
• contributionPlots: a boolean. If TRUE (default), contribution bar plots will be created.
• correlationPlotter: a boolean. If TRUE (default), a correlation circle plot will be created. Applies to PCA family of methods (CA is excluded for now).
• graphs: a boolean. If TRUE, graphs are created. If FALSE, only data associated to plotting (e.g., constraints, colors) are returned.

Returns

The following items are bundled inside of $Plotting.Data:

• **$fi.col**: the colors that are associated to the row items ($fi).

• **$fi.pch**: the pch values associated to the row items ($fi).

• **$fj.col**: the colors that are associated to the column items ($fj).

• **$fj.pch**: the pch values associated to the column items ($fj).

• $constraints: axis constraints for the plots (determines end points of the plots).

Details

epGraphs is an interface between ExPosition and prettyGraphs.

Examples

#this is for ExPosition's iris data
        data(ep.iris)
        pca.iris.res <- epPCA(ep.iris$data)
        #this will put plotting data into a new variable.
        epGraphs.2.and.3 <- epGraphs(pca.iris.res,x_axis=2,y_axis=3)
