[R] How do I show real values on a log10 histogram

[John Kane]

Something like this?  It does an extra y-axis but the principle is the same for an x-axis

# Create the data to be graphed
        x<-1:10
        y1<-x
        y2<-x^2

# Set the par values
        op  <- par(las=1,xaxs="r",mai=c(1,0.75,1,1))

# Draw first plot        
        plot(x,y1,xlim=c(0,10),ylim=c(0,10), ylab="y1", las = 1)
        title(main="Multiple Y-Axes in R")
# Draw second plot
        par(new=TRUE)
        plot(x,y2,xlim=c(0,10),xaxt="n",yaxt="n",ylab="",pch=16)
        axis(4,at=c(0,20,40,60,80,100))
        text(12, 50, "y2", srt = 270, xpd = TRUE)
        par(op)  # reset par
