data.checkout: Check through the source dataset to detect problems

In xpose4: Diagnostics for Nonlinear Mixed-Effect Models

Check through the source dataset to detect problems

Description

This function graphically "checks out" the dataset to identify errors or inconsistencies.

Usage

data.checkout(
  obj = NULL,
  datafile = ".ask.",
  hlin = -99,
  dotcol = "black",
  dotpch = 16,
  dotcex = 1,
  idlab = "ID",
  csv = NULL,
  main = "Default",
  ...
)

Arguments

obj	NULL or an xpose.data object.
datafile	A data file, suitable for import by read.table.
hlin	An integer, specifying the line number on which the column headers appear.
dotcol	Colour for the dots in the dotplot. If obj is an xpose data object then the default is to use the same value as defined for box-and-whisker plots.
dotpch	Plotting character for the dots in the dotplot. If obj is an xpose data object then the default is to use the same value as defined for box-and-whisker plots.
dotcex	Relative scaling for the dots in the dotplot. If obj is an xpose data object then the default is to use the same value as defined for box-and-whisker plots.
idlab	The ID column label in the dataset. Input as a text string.
csv	Is the data file in CSV format (comma separated values)? If the value is NULL then the user is asked at the command line. If supplied to the function the value can be TRUE/FALSE.
main	The title to the plot. "default" means that Xpose creates a title.
...	Other arguments passed to link[lattice]{dotplot}.

Details

This function creates a series of dotplots, one for each variable in the dataset, against individual ID. Outliers and clusters may easily be detected in this manner.

Value

A stack of dotplots.
