Representation of the link between a variable and a set of qualitative variables

represents the link between a variable and a set of qualitative variables.

Usage

sco.boxplot(score, df, labels = names(df), clabel = 1, xlim = NULL, 
    grid = TRUE, cgrid = 0.75, include.origin = TRUE, origin = 0, 
    sub = NULL, csub = 1)

Arguments

score

a numeric vector

df

a data frame with only factors

labels

a vector of strings of characters for the labels of variables

clabel

if not NULL, a character size for the labels, used with par("cex")*clabel

xlim

the ranges to be encompassed by the x axis, if NULL they are computed

grid

a logical value indicating whether the scale vertical lines should be drawn

cgrid

a character size, parameter used with par("cex")*cgrid to indicate the mesh of the scale

include.origin

a logical value indicating whether the point "origin" should be belonged to the graph space

origin

the fixed point in the graph space, for example 0 the origin axis

sub

a string of characters to be inserted as legend

csub

a character size for the legend, used with par("cex")*csub

Examples

w1 <- rnorm(100,-1)
w2 <- rnorm(100)
w3 <- rnorm(100,1)
f1 <- gl(3,100)
f2 <- gl(30,10)
sco.boxplot(c(w1,w2,w3), data.frame(f1,f2))


data(banque)
banque.acm <- dudi.acm(banque, scan = FALSE, nf = 4)
par(mfrow = c(1,3))
sco.boxplot(banque.acm$l1[,1], banque[,1:7], clab = 1.8)
sco.boxplot(banque.acm$l1[,1], banque[,8:14], clab = 1.8)
sco.boxplot(banque.acm$l1[,1], banque[,15:21], clab = 1.8)

par(mfrow = c(1,1))
