sco.distri {ade4}

Representation by mean- standard deviation of a set of weight distributions on a numeric score

Description

represents the mean- standard deviation of a set of weight distributions on a numeric score.

Usage

sco.distri(score, df, y.rank = TRUE, csize = 1, 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 positive or null values

y.rank

a logical value indicating whether the means should be classified in ascending order

csize

an integer indicating the size segment

labels

a vector of strings of characters for the labels of the 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 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

Value

returns an invisible data.frame with means and variances
