I have defined the following function:

> y$par

[1] 1.0029771 0.7610545

This works fine.

Now I want to use these two steps on a dataframe:
mydat<-data.frame(d1=c(3,5),d2=c(6,10),p1=c(.55,.05),p2=c(.85,.35))

> mydat

d1 d2 p1 p2

1 3 6 0.55 0.85

2 5 10 0.05 0.35

where for each row in mydat, I append the two parameter resulting from
optim into mydat.

I want to do this for a larger dataset but thought I would start with a
simple two row dataframe.

I have tried this with loops and the apply function, but seem to be
getting nowhere.

Thanks for any input.
