[R] Change the text size of the title in a legend of a R plot.

[Victor Gabillon]

Hello,

Is it possible to change the text size of the title in a legend of a R plot?

I tried to directly change the title.cex argument but it seems not to work.

Trying :

Horizo <- c(1,2,6,10,20)
legtext <- paste(Horizo,sep="")
legend("topleft", legend=legtext,col=col,text.col=col,lwd=lwd,
lty=lty,cex=1.1,ncol=3,title = "Horizons",title.col ="black",title.cex=1.4)

gives the following error (sorry in french):
Erreur dans legend("topleft", legend = legtext, col = col, text.col = 
col,  :
   argument(s) inutilisé(s) (title.cex = 1.4)

saying title.cex argument as been ignored.

Thank you for helping.

Victor
