You might try investigating text to add labels to the plot and and
legend for a legend. Good luck! - Liam

Hello,
I have probably very silly question about maps of samples, but I'm not able to
figure it out. :-( I wish to generate simple map showing sampling localities of
sampled populations, with various symbols and colors for species and other
characteristics. And with labels for the point showing population abbreviation
and map legend explaining used symbols.
To generate map I use
plot(x=getMap(resolution="high"), xlim=c(0,60), ylim=c(35,50), asp=1, lwd=2)
and to plot localities
points(souradnice2$X.lon, souradnice2$X.lat, pch=souradnice2$symbol,
col=souradnice2$col, cex=2)
Variable „souradnice2“ contains details about localities:
souradnice2
X.lon. X.lat. size col char symbol
"D001" 2.9000 42.9167 big red Fe 15
[...]
„D007“ 21.3333 41.1000 big blue He 17
[...]
"D027" 20.8000 41.1333 big blue Oh 17

"D053" 21.5167 41.9167 big blue Sk 17
"D054" 21.2833 41.9500 big blue Ma 17

I wasn't able to find how to plot also names of populations along the point and
some legend summarizing symbols used to label populations.
Could someone, please, point me to right way how to do it?
All the best,
Vojtěch
