Map treated conditions to their respective references.

Source: R/map_df.R
map_df.Rd

Map treated conditions to their respective Day0, untreated, or single-agent references using condition metadata.

Usage

map_df(
  trt_md,
  ref_md,
  override_untrt_controls = NULL,
  ref_cols,
  ref_type = c("Day0", "untrt_Endpoint")
)

Arguments

trt_md

data.table of treated metadata.

ref_md

data.table of untreated metadata.

override_untrt_controls

named list indicating what treatment metadata fields should be used as a control. Defaults to NULL.

ref_cols

character vector of the names of reference columns to include. Likely obtained from identify_keys().

ref_type

string of the reference type to map to. Should be one of c("Day0", "untrt_Endpoint").

Value

named list mapping treated metadata to untreated metadata.

Details

If override_untrt_controls is specified, the values in the named list will supersede the values in trt_md during the matching process. This is useful for mapping treatments to specific "standard" untreated controls.

  clid = c("C1", "C2"),
  Duration = 72,
  rn = c("R1", "R2")
)
map_df(trt_dt, ref_dt, ref_cols = "clid", ref_type = "untrt_Endpoint")
