chevron (version 0.2.7)

chevron_tlg-class: chevron_t

Description

chevron_t, a subclass of chevron_tlg with specific validation criteria to handle table creation

chevron_l, a subclass of chevron_tlg with specific validation criteria to handle listing creation

chevron_g, a subclass of chevron_tlg with specific validation criteria to handle graph creation

chevron_simple, a subclass of chevron_tlg, where main function is a simple call

Usage

chevron_t(
  main = function(adam_db, ...) build_table(basic_table(), adam_db[[1]]),
  preprocess = function(adam_db, ...) adam_db,
  postprocess = std_postprocessing,
  ...
)
chevron_l(
  main = function(adam_db, ...) data.frame(),
  preprocess = function(adam_db, ...) adam_db,
  postprocess = std_postprocessing,
  ...
)
chevron_g(
  main = function(adam_db, ...) ggplot2::ggplot(),
  preprocess = function(adam_db, ...) adam_db,
  postprocess = std_postprocessing,
  ...
)
chevron_simple()

Value

Arguments

main

(function) returning a tlg, with adam_db as first argument. Typically one of the _main function of chevron.

preprocess

(function) returning a pre-processed list of data.frames, with adam_db as first argument. Typically one of the _pre function of chevron.

postprocess

(function) returning a post-processed tlg, with tlg as first argument.

...

not used

Slots

main

(function) returning a tlg. Typically one of the *_main function from chevron.

preprocess

(function) returning a pre-processed list of data.frames amenable to tlg creation. Typically one of the *_pre function from chevron.

postprocess

(function) returning a post-processed tlg. Typically one of the *_post function from chevron.
