Greetings,  

      I implemented BRugs to run the EWOC model with a cohort size N=1. I output the simulation data using bugsdata(data), where data is the following list.   

> data

$Dose

[1] 140  

$Y

[1] 0  

bugsdata(data) puts out the file data.txt as follows.  

list(Dose=1.40000E+02, Y=0.00000E+00)  

after I type the following line

modelData("data.txt") # read data file  

I get the ERROR:

expected the collection operator c error pos 98 (error on line 1)  

If I rewrite the file

list(Dose=c(1.40000E+02), c(Y=0.00000E+00))  

it runs fine. Can you suggest a way to get the output dataset to automatically put the

c( ) on the data when the sample size is 1?  

Thank you,

Suzette
