MAEFilteredDataset$new()

Initialize MAEFilteredDataset object.

Usage

MAEFilteredDataset$new(
  dataset,
  dataname,
  keys = character(0),
  label = character(0)
)

Arguments

dataset

(MulitiAssayExperiment) single MulitiAssayExperiment for which filters are rendered.

dataname

(character(1)) syntactically valid name given to the dataset.

keys

(character) optional vector of primary key column names.

label

(character(1)) label to describe the dataset.

Returns

Object of class MAEFilteredDataset, invisibly.

---

MAEFilteredDataset$set_filter_state()

Set filter state.

Usage

MAEFilteredDataset$set_filter_state(state)

Arguments

state

(teal_slices)

Returns

NULL, invisibly.

---

MAEFilteredDataset$remove_filter_state()

Remove one or more FilterState of a MAEFilteredDataset.

Usage

MAEFilteredDataset$remove_filter_state(state)

Arguments

state

(teal_slices) specifying FilterState objects to remove; teal_slices may contain only dataname and varname, other elements are ignored.

Returns

NULL, invisibly.

---

MAEFilteredDataset$ui_add()

UI module to add filter variable for this dataset.

Usage

MAEFilteredDataset$ui_add(id)

Arguments

id

(character(1)) shiny module instance id.

Returns

shiny.tag

---

MAEFilteredDataset$get_filter_overview()

Creates row for filter overview in the form of
dataname -- observations (remaining/total) -- subjects (remaining/total) - MAE

Usage

MAEFilteredDataset$get_filter_overview()

Returns

A data.frame.

---

MAEFilteredDataset$clone()

The objects of this class are cloneable with this method.

Usage

MAEFilteredDataset$clone(deep = FALSE)

Arguments

deep

Whether to make a deep clone.

Examples

# use non-exported function from teal.slice
MAEFilteredDataset <- getFromNamespace("MAEFilteredDataset", "teal.slice")

data(miniACC, package = "MultiAssayExperiment")
dataset <- MAEFilteredDataset$new(miniACC, "MAE")
fs <- teal_slices(
  teal_slice(
    dataname = "MAE", varname = "years_to_birth", selected = c(30, 50), keep_na = TRUE

    dataname = "MAE", varname = "gender", selected = "female", keep_na = TRUE
  ),
  teal_slice(
    dataname = "MAE", varname = "ARRAY_TYPE", selected = "", keep_na = TRUE
  )
)
dataset$set_filter_state(state = fs)
