compare function

Create comparison charts for multiple fits

Use compare to quickly compare the estimated parameters of the fits of multiple lmerMod or rlmerMod objects.

compare(..., digits = 3, dnames = NULL, show.rho.functions = TRUE)

## S3 method for class 'lmerMod'
getInfo(object, ...)

## S3 method for class 'rlmerMod'
getInfo(object, ...)

## S3 method for class 'comparison.table'
xtable(
  x,
  caption = NULL,
  label = NULL,
  align = NULL,
  digits = NULL,
  display = NULL,
  ...
)

## S3 method for class 'xtable.comparison.table'
print(
  x,
  add.hlines = TRUE,
  latexify.namescol = TRUE,
  include.rownames = FALSE,
  ...
)

getInfo(object, ...)

Arguments

• ...: objects to compare, or, for the xtable functions: passed to the respective xtable function.
• digits: number of digits to show in output
• dnames: names of objects given as arguments (optional)
• show.rho.functions: whether to show rho functions in output.
• object: object
• x: object of class "comparison.table" or "xtable.comparison.table"
• caption: see xtable.
• label: see xtable.
• align: see xtable.
• display: see xtable.
• add.hlines: replace empty lines in comparison table by hlines. Supersedes hline.after argument of print.xtable.
• latexify.namescol: replace sigma and x in the first column by latex equivalents.
• include.rownames: include row numbers (the object returned by xtable.comparison.table includes names in the first column)

Returns

getInfo returns a list with estimated coefficients, estimated variance components, sigma, deviance and parameter configuration used to fit.

Details

The functions xtable.comparison.table and print.xtable.comparison.table are wrapper functions for the respective xtable and print.xtable functions.

The function getInfo is internally used to prepare object for producing a comparison chart in compare.

Examples

## Not run:

  fm1 <- lmer(Yield ~ (1|Batch), Dyestuff)
  fm2 <- rlmer(Yield ~ (1|Batch), Dyestuff)
  compare(fm1, fm2)
  require(xtable)
  xtable(compare(fm1, fm2))
  str(getInfo(fm1))
## End(Not run)
