geom_smooth parameters no longer available in qplot

[salauer]

In the past, I was able to write the following code:

qplot(data=dat, x=x_var, y=y_var, geom=c("point", "smooth"), se=FALSE, method="lm")

But now that returns the error: "Error: Unknown parameters: se, method"

Of course it isn't too difficult to just add + geom_smooth(se=FALSE, method="lm") but I guess I don't understand why it was taken out of qplot's functionality.

Please provide a reproducible example. There are three things you need to include to make your example reproducible: required packages, data, and code.

1. Packages should be loaded at the top of the script, so it's easy to
   see which ones the example needs. This is a good time to check that you're
   using the latest version of each package: it's possible you've discovered
   a bug that been fixed since you installed the package.
2. The easiest way to include data in a question is to use dput() to
   generate the R code to recreate it. For example, to recreate the mtcars
   dataset in R, I'd perform the following steps:
3. Run dput(mtcars) in R
4. Copy the output
5. In my reproducible script, type mtcars <- then paste.

Try and find the smallest subset of your data that still reveals
the problem.
3. Spend a little bit of time ensuring that your code is easy for others to
read:

• Make sure you've used spaces and your variable names are concise, yet
  informative.
• Use comments to indicate where your problem lies.
• Do your best to remove everything that is not related to the problem.
  The shorter your code is, the easier it is to understand, and the
  easier it is to fix.

Finish by checking that you have actually made a reproducible example by starting a fresh R session and copying and pasting your script in.

(@thomasp85 - I think it's actually slightly different - that issue is to do with aesthetics where as this is parameters. i.e. in this case we should be able to automatically pull the parameters out of the aesthetics)

Just tried this again after a long while and there appears to be no issue. Either "thanks ggplot team!" for fixing it or "sorry ggplot team!" if there was no issue in the first place.
Cheers
