In sdray/ade4: Analysis of Ecological Data: Exploratory and Euclidean Methods in Environmental Sciences

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

  sco.distri(w, distri, csi = 1.5)
