Summarize PM_data objects

Summarize the raw data used for a Pmetrics run.

Usage

# S3 method for class 'PM_data'
summary(object, formula, FUN, include, exclude, ...)

object: A PM_data object.
formula: Optional formula for specifying custom summaries. See aggregate and formula for details on how to specify formulae in R. If, for example, the data contain a covariate for weight named 'wt', then to summarize the mean dose in mg/kg per subject specify formula = dose/wt ~ id and FUN = mean.
FUN: The summary function to apply to formula, if specified. This is not quoted, and usual choices will be mean, median, max, or min.
include: A vector of subject IDs to include in the summary, e.g. c(1:3,5,15)
exclude: A vector of subject IDs to exclude in the summary, e.g. c(4,6:14,16:20)
...: Additional arguments to FUN, e.g. na.rm = TRUE
