Hi,

I would like to know how (if) I can extract some of the information from 
the summary of my nlme.
at present, I get a summary looking something like this:


 > summary(fit.nlme)

Nonlinear mixed-effects model fit by maximum likelihood
   Model: MLKYLD ~ W4(DIM, logA, B, C)
  Data: ADHIS.x0
     AIC      BIC  logLik
   265314 265401.6 -132647

Random effects:
  Formula: list(logA ~ 1 , B ~ 1 , C ~ 1 )
  Level: ID
  Structure: General positive-definite
             StdDev   Corr
    logA 0.480476962 logA   B
       B 0.140839992 -0.855
       C 0.001706867 -0.523  0.819
Residual 3.164491614


Fixed effects: logA + B + C ~ 1
        Value  Std.Error    DF  t-value p-value
logA 3.005178 0.01025308 41835 293.1000  <.0001
   B 0.091446 0.00296687 41835  30.8223  <.0001
   C 0.002727 0.00003245 41835  84.0336  <.0001


Standardized Within-Group Residuals:
       Min         Q1         Med        Q3      Max
  -5.107463 -0.5581999 -0.01962435 0.5032916 31.28465

Number of Observations: 46831
Number of Groups: 4994

I would like to extract the table of correlations, but have not been able 
to do it.

Any assistance, much appreciated.

Cheers,
Evelyn
