scatter.enfa tip (adehabitat)
Dear Consuelo,
If the labels overlap a lot, you won't manage to do anything with it
from R. You can play, as you tried, with the different parameters, or
even build your plot step by step, but my best advice would be to use
the package Cairo, and especially CairoSVG, to export it to svg, and
then edit from Inkscape.
From the example of scatter.enfa :
library(Cairo)
data(lynxjura)
map <- lynxjura$map
## We keep only "wild" indices.
tmp <- lynxjura$locs[,4]!="D"
locs <- lynxjura$locs[tmp, c("X","Y")]
## We perform a square root transformation
## of the variable to normalize it
map[,4] <- sqrt(map[,4])
## We perform the ENFA
tmp <- data2enfa(map, locs[tmp, c("X","Y")])
(enfa1 <- enfa(dudi.pca(tmp$tab, scannf=FALSE),
tmp$pr, scannf = FALSE))
CairoSVG()
scatter(enfa1)
dev.off()
And then check for the svg file in your working directory.
Hope this helps,
Mathieu.

Hi guys,
I just need a quick tip... I'm using the function scatter.enfa to plot my
results, but I have a problem with the labels of the biplot arrows (the
boxes). Two of them overlap... I've been trying to changing the size of the
labels (trying cex.lab, cex.labels), the font of the labels (using font.lab,
font.labels), trying to change the position of the labels (using pos =c()),
but nothing seems to work... is there a way to change the position of the
labels? or, do you have any other idea?
Thanks!!!
Consuelo
