Hello,
i attached an example with two plotted vectors, respectively. And you might
see that the y and x axis are not the same scale (e.g. the third and the
last plot).
I would prefer them to be the same scale.
A toy example:
a<- c (1,2,3,4,5,6,9,20)
b<- c (0.2,0.4,0.6,1,0.5,1,1,0.1)
plot (a,b)
I would like to a have a plot with the same scales for the y and x axis.
Could you please give me a hint how it works.
thanks

Hi Herman,
My guess is that you want the x and y scales to have the same length in
user units and perhaps even to have the same tick positions and values.
For the toy example:
a <- c (1,2,3,4,5,6,9,20)
b <- c (0.2,0.4,0.6,1,0.5,1,1,0.1)
plot (a,b,xlim=c(0,20),ylim=c(0,20))
Adding the solution that Bill provided:
plot (a,b,xlim=c(0,20),ylim=c(0,20),asp=1)
will ensure that the actual intervals on the x and y axes will be the same.
