adegraphics (version 1.0-5)

addtext: Adds labels on graphics.

Description

Adds a trellis object containing one or several labels on one or several graphical objects.

Usage

addtext(object, xcoord, ycoord, label, which = 1, plot = TRUE, pos = -1, ...)

Arguments

object

an object of class ADEg, ADEgS or trellis

xcoord

an integer (or a vector) indicating where label is(are) plotted on the x-axis

ycoord

an integer (or a vector) indicating where label is(are) plotted on the y-axis

label

a character string (or a vector) containing the label(s) displayed on object

which

if object is an ADEgS, which ADEg is used as the base of superposition

plot

a logical indicating if the graphics is displayed

pos

an integer indicating the position of the environment where the data are stored, relative to the environment where the function is called. Useful only if storeData is FALSE

...

Additional graphical parameters (see the plabels list in adegpar and trellis.par.get)

Value

An object of class "ADEgS".

afc1 <- ade4::dudi.coa(dunedata$veg, scannf = FALSE)
g1 <- table.value(dunedata$veg, symbol = "circle", ppoints.cex = 0.5, plot = FALSE)
addtext(g1, 1, 20, "A", plabels.srt = 45)

xy <- cbind.data.frame(x = runif(200, -1, 1), y = runif(200, -1, 1))
posi <- factor(xy$x > 0) : factor(xy$y > 0)
g2 <- s.class(xy, fac = posi, facets = posi, pellipses.col = 1:4, plabels.cex = 0, 
  plegend.drawKey = FALSE, psub.cex = 0, plot = FALSE)
addtext(g2, c(0.5, 0.5, -0.5, -0.5), c(0.5, -0.5), levels(posi), plabels.cex = 2, plabels.col = 1:4)
