[R] Query on contour plots

[Neotropical bat risk assessments]

Hi all,

I spent some time this morning fiddling with the parameters in the plot 
code provided by Jim and Abby and  by changing some important ones.

Jim did note
*# set the matrix limits a bit beyond the data ranges*
fcsc_mat<-makeDensityMatrix(bfs$Fc,bfs$Sc,nx=100,ny=100,
  zfun="sum",xlim=c(*30,45*),ylim=c(*-55,110*)) and

axis(1,at=seq(5,95,10),round(seq(*30.0,50.0*,length.out=10),1))

axis(2,at=seq(5,95,10),round(seq(*-55,110*,length.out=10),1))

So editing the lines above to match what the data includes the plots for 
various species are working!

I now need to figure out how to add a legend for the density values in 
the bivariate package plots.

I am assuming there can be a line or so of code that can extract the 
min-max values from the actual data files
that will update the xlim, ylim and axis data?  I think this should be a 
simple first step after reading in each new data set.

I can not thank Jim and Abby enough.  Super helpful

Cheers,
Bruce
