Feature selection - parameter naming conflict

[srp33]

I really enjoy working with mlr, but I've run into a little problem, and I'm not sure how to get around it. I'm hoping you can help. I'm trying to do feature selection with the rf.min.depth function. I want to specify a value for the "method" parameter within the underlying library ( randomForestSRC::var.select). But there is also a "method" parameter in the generateFilterValuesData function for the learner name. Below is some example code along with the error I'm getting. I'm running R-3.3.1 and mlr version 2.9.

library(mlr)

parameterValues <- c(method="vh", conservative="low")
task <- makeClassifTask(data = iris, target = "Species")
fv <- generateFilterValuesData(task, method = "rf.min.depth", more.args=list("rf.min.depth"=parameterValues))

Error in randomForestSRC::var.select(getTaskFormula(task), getTaskData(task), :
formal argument "method" matched by multiple actual arguments

Any suggestions?

The problem is that in an internal function method is set directly and via .... Definitely a bug. Going to fix this soon.

@jakobbossek
please close this when it is unit tested

Added test in b8c46bc. Closing.

Sorry for the dumb question, but what can I do if I want to apply this patch to my own analysis? I am currently using version 2.9.

You can install the development version of mlr with devtools:

devtools::install_github("mlr-org/mlr")

Will this be incorporated into version 2.10? If so, how soon do you expect that to be released? Thanks again!

[larskotthoff]

Yes and we expect a release very soon.

monday my holiday starts. i want to push to CRAN before this.

they should hopefully allow a 2nd release in 10 days.

[srp33]

What would be included in the 2nd release?

[larskotthoff]

We are still working on this.

[berndbischl]

What would be included in the 2nd release?

simply read the NEWS in the GH repo. you can see what we are changing there.

Sorry to keep this thread going, but do you know how soon version 2.10 will be live on CRAN? It is still showing as 2.9. Thanks!
