latticist: A Lattice GUI

Description

Interactively visualise a data set using Lattice displays.

Usage

latticist(dat,
          reorder.levels = TRUE,
          plot.call = quote(marginals(dat, reorder=FALSE)),
          ...,
          labels = rownames(dat),
          time.mode = FALSE)

Arguments

dat

a data frame containing numeric and/or categorical variables.

reorder.levels

if TRUE, change the ordering of levels of factor variables so they are in order of frequency. Note that this does not change the data, only its internal representation: see reorder. Th

plot.call

call defining the initial plot display.

..., labels, time.mode

further arguments passed to playwith.

Value

• invisibly returns the playState object representing the plot window: see playDevCur.

Details

Just try it... It is recommended to install hexbin, which is a BioConductor package, as follows: source("http://bioconductor.org/biocLite.R") biocLite("hexbin") To change the style of lattice graphics, use lattice.options(default.theme=...). See show.settings, simpleTheme and custom.theme.

Examples

if (interactive()) {
options(device.ask.default = FALSE)

## CO2 dataset: see ?CO2
## From an experiment on the cold tolerance of a grass species.
## Try: uptake ~ conc
##      uptake ~ conc | Plant
##      uptake ~ conc | Type, groups = Treatment
latticist(CO2)

## National Health and Nutrition Examination Survey.
## Try: ~ Smoke, groups = Sex
##      Sex ~ Smoke
##      Smoke ~ Age | Sex
##      ~ Diet.Iron, groups = Sex
##      Hemoglobin ~ Diet.Iron | Sex
##      (with both x and y "discretized")
if (require(hexbin)) {
  readline("Hit Enter for 'NHANES' example...")
  data(NHANES)
  latticist(NHANES)
}

## audit dataset: artificial data representing tax work.
if (require(rattle)) {
  readline("Hit Enter for 'audit' example...")
  audit <- read.csv(system.file("csv", "audit.csv",
                    package = "rattle"))
  latticist(audit, new = TRUE)
}
