Coerce PBmodcomp objects to data frames

Convert the test result table of a PBmodcomp or summary.PBmodcomp object into a standard data frame for easy inspection or export.

# S3 method for class 'PBmodcomp'
as.data.frame(x, ...)

# S3 method for class 'summary_PBmodcomp'
as.data.frame(x, ...)

Arguments

x

An object of class PBmodcomp or summary_PBmodcomp.

...

Further arguments (currently ignored).

Value

A data.frame containing the test results with attributes preserved.

Details

These methods extract the internal test component (a data frame of test statistics and p-values) from the object and return it as a standard data frame. The original object's attributes are preserved as attributes on the returned data frame.

This is useful for exporting or manipulating bootstrap test results in a tidy form.

Examples

if (FALSE) { # \dontrun{
  sleepstudy$Days2 <- sleepstudy$Days^2
  lmer_fit1 <- lme4::lmer(Reaction ~ Days + Days2 + (1 | Subject), data = sleepstudy, REML=FALSE)
  lmer_fit0 <- update(lmer_fit1, . ~ . - Days2)

  res <- pb2_modcomp(lmer_fit1, lmer_fit0, nsim = 200)
  df  <- as.data.frame(res)
  head(df)

  s <- summary(res)
  as.data.frame(s)
} # }
