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
|
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 |
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")* |
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 |
possub |
a string of characters indicating the sub-title position ("topleft", "topright", "bottomleft", "bottomright") |
Value
The matched call.
