R2 and RMSE functions are deprecated?

[crossxwill]

The R2 and RMSE functions appear to be deprecated. Is this true?

Hello,

You get them now with function postResample()

> set.seed(10)
> pred <- rnorm(100)
> actuals <- rnorm(100)
> postResample(pred, actuals)
       RMSE    Rsquared 
1.383517644 0.003368004 

Regards,
Carlos.

They were accidentally not exported when we switched over to using roxygen for documentation.

You should get them if you use devtools to install caret form here. Otherwise, they will be exported in the next release.
