Fine control of plot
Okay, so what you really want to do is be able to set a wide right margin and draw some segments there? Using layout() is not the best way to go about this: as you've discovered, you can't control the area assigned. You can "cheat" with layout(), as in: layout(matrix(c(1,1,1,2), nrow=1)) but the better way is to see xpd within ?par as described here: https://stat.ethz.ch/pipermail/r-help/2009-July/206311.html along with par()$mai to set the margins appropriately.

Hi and thank you for your answer. Sorry for the html post, here's the code: (you missed a break line between +x and plot(...) layout(matrix(c(1,2), 1, 2, byrow = TRUE), widths=c(6,2), heights=c(1,1)) x = 1:100 y = rnorm(x)+x plot(x,y) reg = lm(y~x) abline(reg, col = "red") plot(1, type="n", axes=F, xlab="", ylab="", xlim = c(-1,1), ylim = c(min(y), max(x))) segments(-0.25,min(reg$fitted.values),0.25,min(reg$fitted.values)) segments(-0.25,max(reg$fitted.values),0.25,max(reg$fitted.values)) segments(0,min(reg$fitted.values),0,max(reg$fitted.values)) I hope my question is more obvious after you urn this example.

I'm trying to create a graph where I could plot some lines on the right side. Here an example: layout(matrix(c(1,2), 1, 2, byrow = TRUE), widths=c(6,2), heights=c(1,1)) x = 1:100y = rnorm(x)+xplot(x,y) reg = lm(y~x)abline(reg, col = "red") plot(1, type="n", axes=F, xlab="", ylab="", xlim = c(-1,1), ylim = c(min(y), max(x)))segments(-0.25,min(reg$fitted.values),0.25,min(reg$fitted.values))segments(-0.25,max(reg$fitted.values),0.25,max(reg$fitted.values))segments(0,min(reg$fitted.values),0,max(reg$fitted.values))
I figured out where the linebreaks go, but I can't run this: y = rnorm(x)+xplot(x,y) What's xplot() doing here?
However, I cant figure out how to make it a bit nicer by removing extra space to the right.
Can you explain further what you're trying to do? Plot spacing is controlled with par() for base graphics, but I really don't understand what you're after.
