Dear R-help members,
I did the following pie chart:
R:Code=
plants<-c(11,5,4,4,4,3,3,3,3,3,3,2,2,2,2,2,2,43)
pie(plants,labels =plant_labels,cex=0.7, col=colors)
par(mar=c(0,0,4,0),oma=c(0,0,0,0))
legend(1,1,cex=0.7,pt.cex=25,
c("Rubiaceae","Aspleniaceae","Compositae","Euphorbiaceae","Piperaceae","Acanthaceae","Dryopteridaceae","Cucurbitaceae","Rosaceae","Rutaceae","Urticaceae","Apocynaceae","Cyperaceae","Gramineae","Labiatae","Leguminosae","Menispermaceae","Rest
(50 families)"),fill=colors)
As you can see the legend is not displayed proberly.
1)How can I move the pie chart as well as the legend together to the left? I
tried to work with "mar" and "omar", without any success.
2) How can I increase the legend font size without increasing the size of the
"legend points"? I tried to do this with "cex" and "pt.cex2
Thank you very much
all the best
Michi
