Contribute to PPBstats

Contributions to PPBstats are very welcome and can be made in four different ways:

  1. testing the package and reporting bugs,
  2. improving the code,
  3. improving the documentation and
  4. translating

Anyhow, send me an email if you wish to participate in order to coordinate our efforts:

Test and report bugs

First, download and install the current version of the package here.

The easiest way to start is to look at the book to know how the package works.

Do not hesitate to let a message in the issues if

  • some points are not clear in the book or you find bugs
  • you find bugs with your data (If so, you can send it to me so that I can see where could be the problems)

Improve the code

The code of PPBstats is on github : https://github.com/priviere/PPBstats

Resolve open issues

Do not hesitate to contribute to open issues.

Add new functions

If you have any ideas,

  • on the improvement of the current package (graph or table for example)
  • on new functions that may be useful in the analysis found within PPB programmes regarding network of seeds circulation, agronomic trials, organoleptic tests and molecular experiments.
  • …

even if it is not R written, send me an email and we’ll see how we can work together!

If you wish to add a new model, you should follow different steps :

  • create the model function
my_model <- function(...){
  ...
  ...
  ...
  class(out) = c("PPBstats", "fit_my_model")
  return(out)
  }
check_model.fit_my_model <- function(x){
  ...
  ...
  ...
  class(out) <- c("PPBstats", "check_my_model")
  return(out)
  }
  • create the check_my_model method for plot() 
plot.check_my_model <- function(x, y, ...){
  ...
  ...
  ...
  }
mean_comparisons.check_my_model <- function(x, ...){
  ...
  ...
  ...
  class(out) <- c("PPBstats", "mean_comparisons_my_model")
  return(out)
  }
  • create the mean_comparisons_my_model method for plot() 
plot.mean_comparisons_my_model <- function(x, y, ...){
  ...
  ...
  ...
  }

Internal function structure

The internal function used in PPBstats are presented in Figure below. Note that one additional funtion is also defined in the package: common_functions which gather some functions used in several functions of PPBstats.

Internal functions used within main functions.

A description of each function can be found here

Improve the documentation

The book has been generated thanks to bookdown.

If you wish to improve the web site, the book, to add new sections on PPB, etc please file an issue or send me an email :

Web site of PPBstats

The code of the website, generated by pkgdown, is on github: https://github.com/priviere/PPBstats/tree/master/vignettes. To test any changes on the website:

pkgdown::build_site()

Book

The code of the book is on github: https://github.com/priviere/PPBstats/tree/master/inst/bookdown

If you are not familiar with the code, you can edit docx documents that can be downloaded here. Do not pay attention to strange words such as #, [@blablabla], \@ref … that are bookdown specific.

If your familiar with the code, to test any changes on the book:

bookdown::serve_book(dir = "inst/bookdown/")

Note that it may be useful not to run the book for all files, which is a bit long … You can edit _bookdown.yml by adding rmd_files argument. Below is an exhautive list with all files.

book_filename: "PPBstats_book"

Web site with examples of reports

The code regarding examples of report fo farmers is on github: https://github.com/priviere/PPBstats/tree/master/inst/return_report_web_site.

To test any changes on the website:

rmarkdown::render_site("inst/return_report_web_site/")

Translate

The package and the book are in english. Every contributions to other languages are welcome! More information on R package translation here.
