Retrieve raw statistic values from a tplyr_build result

Source: R/numeric_data.R
tplyr_stats_data.Rd

Filters the raw numeric data for a specific layer and statistic. Use tplyr_numeric_data() to get every statistic for the layer.

Usage

tplyr_stats_data(result, layer, statistic)

Arguments

result

A data.frame produced by tplyr_build()

layer

Integer layer index (1-based)

statistic

Character string naming the statistic column to extract (e.g., "n", "pct", "mean", "sd")

Value

A data.frame with the layer's grouping columns and the requested statistic. Returns NULL if the layer has no numeric data or does not compute the statistic.

Examples

spec <- tplyr_spec(
  cols = "TRT01P",
  layers = tplyr_layers(group_desc("AGE"))
)
built <- tplyr_build(spec, tplyr_adsl)
tplyr_stats_data(built, 1, "mean")
#>                 TRT01P     mean
#> 1              Placebo 75.20930
#> 2 Xanomeline High Dose 74.38095
#> 3  Xanomeline Low Dose 75.66667
