Re: [R] plot with two y axes BUT unaligned x axis
Use the `xlim` parameter of the `plot` function. IFor example, if X1 and X2 are the variables that contain the values of your x-axis, do xlim1 - range(X1,X2), than do plot(, xlim = xlim1,...) Hope this helps. 2011/6/15 bjmjarrett bjmjarr...@gmail.com Hi all, I have scoured the archives of this forum but nothing quite seems to fit the bill... I would like to plot a graph displaying two variables (y axes) that share date as the x axis. However, the date values for each variable are not the same - for example, some parasitoids were not released on days that collections from the trap took place, whilst sometimes releases did occur on the same day. I would like to align them. My code is: CollectionDate-as.Date(CollectionDate,%m/%d/%Y) # days that had collections release.date.Total-as.Date(release.date.Total,%m/%d/%Y) # days that had releases par(mar=c(5,4,4,4)+0.1) plot(CollectionDate[data$Trap==DPAU1],TotalP[data$Trap==DPAU1],type=n,ylim=c(0,80),xlab=Time,ylab=Number of egg masses) # I am using one trap of many lines(CollectionDate[data$Trap==DPAU1],TotalP[data$Trap==DPAU1],lwd=2) par(new=T) plot(release.date.Total[data$Trap==DPAU1],parasitoid.total[data$Trap==DPAU1],axes=F,type=h,lty=1,col=red,xlab=,ylab=,lwd=1.2) axis(4,las=1) mtext(side=4,line=3,Total parasitoids released) ### As in the above code, I suppressed the axes for the second plot, but if I don't the x axis (date) has two tick marks for each year. Is there a way to align the date objects to begin with without compromising the graphs themselves?
