sco.class {ade4}

R Documentation

1D plot of a numeric score and a factor with labels

Description

Draws evenly spaced labels, each label linked to the corresponding values of the levels of a factor.

Usage

sco.class(score, fac, label = levels(fac), clabel = 1, horizontal = TRUE, 
    reverse = FALSE, pos.lab = 0.5, pch = 20, cpoint = 1, boxes = TRUE, 
    col = rep(1, length(levels(fac))), lim = NULL, grid = TRUE, 
    cgrid = 1, include.origin = TRUE, origin = c(0, 0), sub = "", 
    csub = 1.25, possub = "bottomleft")

Arguments

`score`	a numeric vector
`fac`	a factor
`label`	labels for the levels of the factor
`clabel`	a character size for the labels, used with `par("cex")*clabel`
`horizontal`	logical. If TRUE, the plot is horizontal
`reverse`	logical. If horizontal = TRUE and reverse=TRUE, the plot is at the bottom, if reverse = FALSE, the plot is at the top. If horizontal = FALSE, the plot is at the right (TRUE) or at the left (FALSE).
`pos.lab`	a values between 0 and 1 to manage the position of the labels.
`pch`	an integer specifying the symbol or the single character to be used in plotting points
`cpoint`	a character size for plotting the points, used with `par("cex")*cpoint`. If zero, no points are drawn
`boxes`	if TRUE, labels are framed
`col`	a vector of colors used to draw each class in a different color
`lim`	the range for the x axis or y axis (if horizontal = FALSE), if NULL, they are computed
`grid`	a logical value indicating whether a grid in the background of the plot should be drawn
`cgrid`	a character size, parameter used with par("cex")* `cgrid` to indicate the mesh of the grid
`include.origin`	a logical value indicating whether the point "origin" should belong to the plot
`origin`	the fixed point in the graph space, for example c(0,0) the origin axes
`sub`	a string of characters to be inserted as legend
`csub`	a character size for the legend, used with `par("cex")*csub`
`possub`	a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright")

Value

The matched call.
