sco.label {ade4}  R Documentation 
Draws evenly spaced labels, each label linked to the corresponding value of a numeric score.
sco.label(score, label = names(score), clabel = 1, horizontal = TRUE, reverse = FALSE, pos.lab = 0.5, pch = 20, cpoint = 1, boxes = TRUE, lim = NULL, grid = TRUE, cgrid = 1, include.origin = TRUE, origin = c(0, 0), sub = "", csub = 1.25, possub = "bottomleft")
score 
a numeric vector 
label 
labels for the score 
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 
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 subtitle position ("topleft", "topright", "bottomleft", "bottomright") 
The matched call.
