list output truncated - How to show full listLearners()

Question

In mlr package i try to see all options of

listLearners()

But I see just first 6 elements. I try other methods like

listLearners("regr")[1:10, c("class","package")]

But however

       class      package
1  regr.blackboost mboost,party
2     regr.cforest        party
3       regr.ctree        party
4    regr.cvglmnet       glmnet
5 regr.featureless          mlr
6    regr.gamboost       mboost
... (10 rows, 2 cols)

How to fix it? Global options? Length?

mlr uses the printHead() function from the BBmisc package quite heavily for printing objects. Note that it has a parameter n that allows you to specify how many things to show. You can set this when printing, for example

print(listLearners(), n = 100)

The following preserves the formatting in the console window:

 as.data.frame(listLearners("regr")[1:10, c("class","package")])
