[R] Plotting two y-axis vs non-numeric x-axis

[arun]

Hi,

You could use ?twoord.plot() from library(plotrix):
library(plotrix)
dat2<- data.frame(month,music,actor)
dat2$month<- factor(month,labels=c(month.abb,"Pag"))
dat2New<-dat2[order(dat2$month),]

 with(dat2New,twoord.plot(month,music,actor,
                        lylim=c(0,1),rylim=c(0,13000),
                        ylab="Music",
                        rylab="Actor",main="Enjoy",
                        type=c("p","b"),lcol=1,rcol="red",xtickpos=month,xticklab=month))
     legend(5,13000,legend=c("Music","Actor"),text.col=c("black","red"),col=c("black","red"))   

#I tried to change the plotting symbol using "pch" inside the twoord.plot(), but it seems to be not working. 
 with(dat2New,twoord.plot(month,music,actor,
                         lylim=c(0,1),rylim=c(0,13000),
                         ylab="Music",
                         rylab="Actor",main="Enjoy",
                         type=c("p","b"),pch=c(1,4),lcol=1,rcol="red",xtickpos=month,xticklab=month))
#Error in localWindow(xlim, ylim, log, asp, ...) : 
 # formal argument "pch" matched by multiple actual arguments

A.K.

Subject: [R] Plotting two y-axis vs non-numeric x-axis

Hi dear all, the following code is correct. but I want to use non-numeric
x-axis, for example
if I replace   time <- seq(0,72,6)  by
month <-
c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec","Pag")

Ofcourse I use factor(month)  instead of time; but I didn't get similar
plot as the example shown. any help is greatful ;)

month <-
c("Jan","Feb","Mar","Apr","May","Jun","Jul","Aug","Sep","Oct","Nov","Dec","Pag")
music <- c(0.05,0.18,0.25,0.31,0.32,0.34,0.35,
0.36,0.37,0.38,0.39,0.40,0.41)
actor <- c(0,1000,2000,3000,4000,5000,6000,7000,8000,9000,10000,11000,12000)
par(mar=c(5, 4, 4, 4) + 0.1)
plot(factor(month), music, pch=16, axes=F, ylim=c(0,1), xlab="", ylab="",
type="b",col="black", main="Enjoy")
axis(2, ylim=c(0,1),col="black")
mtext("Music",side=2,line=2.5)
box()
par(new=T)
plot(factor(month), actor, pch=15,  xlab="", ylab="", ylim=c(0,13000),
axes=F,  type="b", col="red")
mtext("Actor",side=4,col="red",line=2.5)
axis(4, ylim=c(0,13000), col="red",col.axis="red")
axis(1,pretty(range(month),10))
mtext("Month",side=1,col="black",line=2.5)
legend(5,13000,legend=c("Music","Actor"),text.col=c("black","red"),pch=c(16,15),col=c("black","red"))
