Description

produce post-filter Tasks for mlr3

Usage

se_to_filtered_task(
  taskid,
  se,
  classvar,
  nfeat = 100,
  tmaker = mlr3::TaskClassif,
  filtfun = function(x) flt("variance")$calculate(x, nfeat = nfeat),
  ...
)

Arguments

taskid	character(1) arbitrary label
se	SummarizedExperiment instance
classvar	character(1) optional name of colData element to use for classification
nfeat	numeric(1) number of features to retain
tmaker	a Task as defined in mlr3
filtfun	a function that computes a Filter score in the mlr3filters framework, defaults to the "variance" scoring method
...	passed to 'tmaker$new()' for the filtered task production
