Hi all,

I'm trying to use the R growth curve analysis package Grofit. I've used it
successfully before but the protocol which previously worked for me is now
not giving me the expected output.

Entering my data and time info and running Test<-grofit(time,data,FALSE)
gives me the expected growth curves as plots for my consideration. However,
when I try to access the output of gcfit using either summary(Test,gcfit) or
summary(Test$gcfit) I don't get the raw growth curve data which I expect, i.e. the 'hard' quantified info from the fitted growth curves, but instead seem to get information about the data that I entered and the running of the process:> summary(TestRun2,gcfit)

        Length
Class          Mode   

time    55     data.frame     list 
 

data    58     data.frame     list  


gcFit    7     gcFit          list  


drFit    1     -none-         logical

control 16    
grofit.control list   
I've tried using the in-package generated data and get the same output. I
can't see why the same protocol now doesn't work, except that the package is
a later version than the one I previously used. Also, the package is now
'orphaned'.

Can anyone give any advice? Would loading an earlier version of the package
from the tar.gz file be an option? I'm a bit shaky on getting this to work
(I had a bit of a go using the instructions here):

but wasn't entirely successful....

Thanks for any suggestions!
