[R] Plot graph with different symbol size
Dear All, This is regarding symbols function. I'm preparing a graph for different species in a plot (based on the coordinate x y). I used inches in symbol function to indicate the different symbols size based on the size class (in diameter of tree trunk). The problem is that the symbol size is arrange in descending order. So the symbol for two species with different number of size class will have the same symbol size for the largest of each species diameter class (descending order). If the species A has 3 size class (e.g 10,20,30); and another species B has 5 size class (10,20,30,40,50), the symbols size display is the same for species A is the same as symbol size for species B for size class 30,40,50. How can I solve the problem? Example of my program code: dbhcat=cut(spdata$dbh,breaks=c(10,50,100,300,600,10),labels=c(1,2,3,4,5)) symbols(spdata$gx,spdata$gy,dbhcat,inches=c(0.05,0.1,1.5,2.0,2.5,3.0),add=TRUE) Abd.

Re: [R] Plotting contour filled.contour in one graph
Dear Spencer, Thanks for the assistance and the website. It will be very helpful for my future code programming on graph in R. Abd. Rahman - Original Message - From: Spencer Graves [EMAIL PROTECTED] To: Michael Prager [EMAIL PROTECTED] Cc: Gabor Grothendieck [EMAIL PROTECTED]; R Help List r-help@stat.math.ethz.ch; Abd Rahman Kassim [EMAIL PROTECTED] Sent: Sunday, February 12, 2006 12:40 PM Subject: Re: [R] Plotting contour filled.contour in one graph Hi, Michael: I'm sure the example would be clearer AND more interesting if you used real data AND accompanied it with a description like you gave below. To help motivate the usage, you could add a few words of interpretation, e.g., that if you want both z and zz less than 2, x and y must be in the upper right corner. Thanks for this. spencer graves Michael Prager wrote: GG Yes, gladly. It is an idealized example of the following data situation: There are two control or independent variables. They are represented here as x and y, on the horizontal and vertical axes respectively. There are two different responses or dependent variables plotted as different types of contours. The filled contours show response z. The heavy lines show response zz. Thus such a plot displays two different responses from a two-dimensional range of conditions. As an example, in fishery biology, x might be the age at which fish are first subject to capture, y might be the fishing mortality rate (intensity) applied, z might be the resulting yield per fish, and zz might be the resulting spawning per fish. There is usually a trade-off between yield and spawning potential, and such a graph (if done with real data) allows one to look at that trade-off. The OP seemed to be seeking a way of contouring two responses against two independent variables, and that's what this graph does. Is that clearer? Would the graph would be better if I used real data?
