[R] Fine control of plot

[philippe massicotte]

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. 

Regards, 
Phil
