Hi,
I would like to have six dot plots on one page. I make the plots in a 'for loop' because it is six times the same graph but for different subjects (species). I tried it with "par(mfrow=c(3,2), oma=c(3,3,2,0), mar=c(2,2,2,2))"; but this does not work for dot plots apparently. Then I tried with print(). But then I had to give the dot plots names. This also does not work. Any one who has some more ideas? What do I do wrong? species.vector<-c("Lp","Pp","Pl","Ra","Lc","Ml") for(i in 1:6){ XXXX<- inputdot[inputdot$sp_==species.vector[i],] str(XXXX) XX7<-subset(XXXX,chamber==7) XX8<-subset(XXXX,chamber==8) XX9<-subset(XXXX,chamber==9) XX10<-subset(XXXX,chamber==10) species.vector[i] <- dotplot(XX7$BG_dry~XX7$stress,ylim=c(0,20),ylab="biomass",scales=list(ti ck.number=10), panel = function (x, y) { panel.abline(v=c(1:8),lty=2,col="gray") panel.xyplot(x, y, pch = 1, col = "blue", cex = .75) panel.xyplot(XX8$stress,XX8$BG_dry, pch = 16, col = "red", cex = .6) panel.xyplot(XX9$stress,XX9$BG_dry, pch = 2, col = "blue", cex = .6) panel.xyplot(XX10$stress,XX10$BG_dry, pch = 17, col = "red", cex = .6) }, key = list(text = list(c("ch7", "ch8","ch9","ch10"), cex = .75), points = list(pch = c(1, 16,2,17), col = c("blue","red","blue","red"), cex = .75), space = "bottom", border = T),main=species.vector[i]) ) } print(Lp, split=c(1,1,2,3), more=TRUE) print(Pp, split=c(2,1,2,3), more=TRUE) print(Pl, split=c(1,2,2,3), more=TRUE) print(Ra, split=c(2,2,2,3), more=TRUE) print(Lc, split=c(1,3,2,3), more=TRUE) print(Ml, split=c(2,3,2,3)) Thanks a lot!
