In wfforrest/maeve: Modeling Accessories Enabling Visualization of Experiments

Description

Create a data frame with group_name assignments permuted randomly with respect to the subject_ID values.

Usage

permute_study(
  data_frame,
  random_seed = NULL,
  group_name = maeve_options("group_name"),
  subject_ID = maeve_options("subject_ID"),
  x_name = maeve_options("x_name")
)

Arguments

data_frame	data frame with factors for group and ID, numerics for time on study and response.
random_seed	numeric passed to base::set.seed()
group_name	character. See ?maeve_options().
subject_ID	character. See ?maeve_options().
x_name	character. See ?maeve_options().

Examples

 cat('Example for permute_study() in dontrun{} code block.')
 ## Not run: 
 data( vismodegib )
 vismo30 <- dplyr::filter( vismodegib, DAY_OF_STUDY <= 30 )
 vismo30 <- dplyr::mutate( vismo30, y = log( 1 + TUMOR_VOLUME ) )
 vismo30_permuted <- permute_study( vismo30, random_seed = 12345 )
 ## see outcome of permutation:
 fig_vismo_orig <- draw_study( vismo30,          ncol_value = 5, endpoint_name = 'y' )
 fig_vismo_perm <- draw_study( vismo30_permuted, ncol_value = 5, endpoint_name = 'y' )
