Hi all,

I am trying to plot a number of non-linear curves in ggplot (it's actually loglogistic, but I can't imagine that would make a difference). I have a function `loglogistic_fn(x, omega, theta)`

. I have a data frame (called `df1`

) with many different `omega`

and `theta`

possibilities, and I want to show each of them on 1 graph.

If I had was just trying to plot one version, and stored the variables as `omega0`

and `theta0`

, I could plot it as

```
ggplot(data = tibble(x = 0:17), aes(x)) +
stat_function(fun = loglogistic_fn, args = list(omega = omega1, theta = theta1))
```

If I was just adding in one or two other curves, I could just copy/paste the second line, changing the arguments of `omega`

and `theta`

, but I have too many to do it manually. Is there an automatic way to do it in ggplot? I tried doing

```
ggplot(data = tibble(x = 0:17), aes(x)) +
stat_function(fun = loglogistic_fn, args = list(omega = df$omega, theta = df$theta))
```

but that did not work.

Thanks for your help,

Alan
