BiplotGUI (version 0.0-5)

Biplots: Interactive Biplots in R

Description

Initialises a GUI with which to construct and interact with biplots.

Usage

Biplots(Data, groups = rep(1, nrow(Data)),  
          PointLabels = rownames(Data),  
          AxisLabels = colnames(Data), excel = NULL,  
          ExcelGroupsCol = 0)

Arguments

Data

A matrix or data frame of numerical data. Its $n$ samples (observations) will be represented as points in the biplots; its $p$ variables will be represented as calibrated biplot axes.

groups

A vector or factor of length $n$ specifying the group membership of the samples. By default, all samples are taken to be from a single group. The group labels are taken from this argument, deprecated to 14 characters each.

PointLabels

A vector of length $n$ specifying the point labels. By default, the point labels are taken to be the row names of Data.

AxisLabels

A vector of length $p$ specifying the axis labels. By default, the axis labels are taken to be the column names of Data, deprecated to 14 characters each.

excel

Deprecated as from version 0.0-4.1.

ExcelGroupsCol

Deprecated as from version 0.0-4.1.

Details

Biplots is the sole function of the BiplotGUI package. The function initialises the GUI for a particular data set. All further options are available from within the GUI. The GUI features themselves are documented in a separate manual available from the Help menu of the GUI. The manual is also included as a vignette to the package. Due to the removal of the xlsReadWrite package from CRAN, the direct import of data from Excel 1997-2003 files has been deprecated as from BiplotGUI 0.0-4.1. As an alternative mechanism, consider the RODBC package. At present, BiplotGUI is intended to be run under Windows. In Windows, it runs marginally better in SDI mode, rather than MDI mode.
