I have tried multiple different methods to figure out how to get a date axis of my preference (start date of each month). Any assistance would be appreciated. The below section is not producing a date axis:
plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Emax),xaxt="n") *xlabels<-(strptime(totaldays$totaldays,"%Y-%m-%d",tz="")) xlabels<-xlabels[xlabels$mday==1] axis.Date(1,at=xlabels,format="%b-%Y")* The above section is used in the following plot: par(mfrow=c(4,1)) par(mar=c(0.8,0,0,0)) par(oma=c(2,4.5,3,2)) plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Dmax),xaxt="n") points(D$date,D$TSP,col=Dcol,type="p",pch=16,lwd=2,xaxt="n") text(mdate,Dmax-20,labels="DM1'",cex=1) legend("topright",pch=16,cex=0.8,col=colLegend, legend=ALegend) abline(h=Target,col="red",lwd=2) plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Bmax),xaxt="n") points(B$date,B$TSP,col=Bcol,type="p",pch=16,lwd=2,xaxt="n") text(mdate,Bmax-20,labels="DM2",cex=1) abline(h=Target,col="red",lwd=2) plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Amax),xaxt="n") points(A$date,A$TSP,col=Acol,type="p",pch=16,lwd=2,xaxt="n") text(mdate,Amax-20,labels="DM3",cex=1) abline(h=Target,col="red",lwd=2) plot(totaldays$totaldays,totaldays$y,type="n",ylim=c(0,Emax),xaxt="n") *xlabels<-(strptime(totaldays$totaldays,"%Y-%m-%d",tz="")) xlabels<-xlabels[xlabels$mday==1] axis.Date(1,at=xlabels,format="%b-%Y")* points(E$date,E$TSP,col=Ecol,type="p",pch=16,lwd=2) text(mdate,Emax-20,labels="DM4'",cex=1) abline(h=Target,col="red",lwd=2) title(main=Amain, ylab=Labely, outer=TRUE,cex.lab=1, cex.main=1.5) Below is an excerpt of the total days data: totaldays y 1 2013-11-01 1 2 2013-11-02 1 3 2013-11-03 1 4 2013-11-04 1 5 2013-11-05 1 6 2013-11-06 1 7 2013-11-07 1 8 2013-11-08 1 9 2013-11-09 1 10 2013-11-10 1 -- View this message in context: http://r.789695.n4.nabble.com/no-x-label-using-axis-Date-tp4692034.html Sent from the R help mailing list archive at Nabble.com. ______________________________________________ R-help@r-project.org mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide http://www.R-project.org/posting-guide.html and provide commented, minimal, self-contained, reproducible code.
