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

[John Kane]

Hi Shane.  
I don't know.  I am not clear on what you are asking.  I would think that it would but can you supply some stripped-down code for people to have a look at?  

See https://github.com/hadley/devtools/wiki/Reproducibility  and/or 
 http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example for some suggestions on how to do this.

Oh and please don't reply in html.  The R-help list strips html and while everything came through fine here, it can really jumble code if when the html is removed.

BTW you only replied to me. It is a lot better to reply to the group especially as a lot of R-help people are a lot more knowledgeable than I am and you often can get faster responses.  I have included the R-help list in this response.

Hi John,

I have four plots in a matrix format and Im already using par, if I use your code below the graph will not export as one of the four in the matrix, is there a way of overcoming this?

Thanks for your help.

Cheers

	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
