[R] plot only x- and y-axis with origin, no box()

[Talloen, Willem [PRDBE]]

Yes Greg,

Your provided solution does the job;
> plot(5:10, 5:10, bty='n')
> library(TeachingDemos)
> lines(cnvrt.coords( c(0,0,.5), c(.5,0,0), input='plt')$usr)

The easy way is indeed to do 
> plot(.., bty='l')
but this cannot be used in combination with fixing tickmarks and changing width of the axes.

HOWEVER, there is still a small error. The width of the added y-axis has not the same width;
> plot(5:10, 5:10,axes=F)
> axis(1,lwd=2)
> axis(2,lwd=2)
> library(TeachingDemos)
> lines(cnvrt.coords( c(0,0,.5), c(.5,0,0), input='plt')$usr,lwd=2)

Any ideas?
Willem

Try:

> plot(.., bty='l')

Does that do what you want?  (see the bty parameter in ?par for details)

If you don't want the lines extending beyond the axes on the right and
top then you could do something more like:

> plot(5:10, 5:10, bty='n')
> library(TeachingDemos)
> lines(cnvrt.coords( c(0,0,.5), c(.5,0,0), input='plt')$usr)

You may also get what you want by playing with the xaxp and yaxp
parameters to par, but the bty='l' seems the easiest way to go.
