R help - Jan 2010 - [R-sig-eco] How to create axes in arbitrary positions?

Dear Zongshan Li,

  I'm forwarding this back to r-help ... it's generally best to keep the
conversation going in public, so that (a) other people can chime in with
ideas and suggestions, (b) your question doesn't get lost if the
original respondent doesn't have time to deal with it, (c) the answers
are archived for future reference.

  Your example (I've attached it, hope it makes it through but it may
not) helps.  Here is a crude example approximately along the same lines.
> x = 1850:2000
> y1 = runif(length(x))+0.5
> y2=seq(0,100,length=length(x))
> plot(x,y1,ylim=c(0,1.5))
> library(Hmisc)
> ?subplot
> subplot({plot(x,y2,axes=FALSE); axis(side=4)},x=range(x),y=c(0,0.5))

Dear Ben Bolker:
            I appeciate your introducing functions very much for my
question, and I am glad that your kindly intention to give me further help.
            I guess the function layout might draw plots at the
specified locations, but i still be confused about the exact meaning of
parameter: mat
             layout(mat, widths = rep(1, ncol(mat)), heights = rep(1,
nrow(mat)), respect = FALSE)
             the attached jpg file is an example of the kind of
graphics, and would you like to give me some comments how to draw this
kind of graphics in R?
             Thanks, again.

Best regards,

ZongShan(Sat, January 2, 2010 )

  See ?layout, ?subplot in the Hmisc package; in the ?par help page, you
may also want to see "new", "mfrow", "mfcol".

  Not quite sure what you're asking (posting an example of the kind of
graphics you want to a web page somewhere is sometimes helpful) but
maybe this helps.
