[R-sig-eco] output from ordisurf

[Christopher Chizinski]

Is there a way to output the X,Y,Z values for the contour lines from 
ordisurf?  

For example, I am using this statement:
tmp<-with(enviro,ordisurf(fish.nmds,enviro$Temp,choices=c(1,2),add=TRUE))

names(tmp)
 [1] "coefficients"      "residuals"         "fitted.values"   
 [4] "family"            "linear.predictors" "deviance"        
 [7] "null.deviance"     "iter"              "weights"         
[10] "prior.weights"     "df.null"           "y"               
[13] "converged"         "sig2"              "edf"             
[16] "hat"               "boundary"          "sp"              
[19] "nsdf"              "Ve"                "Vp"              
[22] "mgcv.conv"         "gcv.ubre"          "aic"             
[25] "rank"              "gcv.ubre.dev"      "method"          
[28] "smooth"            "formula"           "cmX"             
[31] "model"             "control"           "terms"           
[34] "pterms"            "assign"            "offset"          
[37] "data"              "df.residual"       "min.edf"         
[40] "call"

I would like to get these XYZ values or find a way to calculate them 
from the output for inclusion into SigmaPlot.  It is probably an easy 
solution but I could not find what I needed.

Thanks for any help or insight.
