I'm working in Rosario, Argentina, trying to plot some contours.
I found the function "draw.contour" created by James Forester at
R-bloggers. If you take a look at that function you'll see it's very
useful!
But I have a problem with it and James is trying to help me (but also
asked me to seek for more help) I hope you can help me (don't worry if you
can't):
Using "draw.contour" I get the contour but I want to place it in a
cartesian-coordinate system where x = "Componente 1" range between -1 y 1
and y = "Componente 2" range between 0 and 3, regardless of xrange or
yrange.
Of course, xrange and yrange are important to obtain an adequate contour
plot but I want to see that contour in the cartesian coordinate system I
told you before.
so I put ylim = c(0,3) and xlim = c(-1,1) but R ignores those sentences
and gives me a graphic using xrange and yrange as limits
can anyone help me? I hope you can understand my problem (and my poor
english!!!). if you don't, tell me and i'll send you more information
thank you very much!!!
My advice would be to use the contour() function, rather than
"draw.contour". I would guess the latter was written to solve a
particular problem, whereas contour() is the general purpose function in
base R, and it does respect your requests for xlim and ylim.
