Project: permutation1

Project for developing a permutation function.

Install

devtools::install_github("aumath-advancedr2019/Permutation1", build_vignettes = TRUE)

Troubleshooting

In the case that after installing the package R prints an error about corruption of the package you can solve the issue by:

• Restating R and loading package again
• Remove and Reinstall package from github

Explaination of the project:

We want to make a package, that can make permutations for data, that needs a non-parametric method. It needs to be able to permute a dataset and compare observed statistical value with permuted values.In addition, it needs to be able to make a different number of permutations conditional on what is chosen. We want it to be able to calculate different statistical values for making a p-value depending on what is chosen for the dataset.Moreover,we want it to compute a p-value, that tells us how likely our observed statistical value is. Also, we want a function to plot our permuted values nicely with the observed statistical value to get a nice graphical representation of it and get a visual idea of how significant it is. Finally, We want it to be able to check, if the data can be used in a parametric test, then we want to break the function and say that permutation takes “this” many iterations (lot of time) and that it might be better to do a parametric test.

Roadmap:

gamma:

1) Create permuation algorithm (permutation + p-value + plot)
2) Minimum interface + first documentations (help and vignette)

beta:

3) Develop functionalities + classes
4) Create package + documentation (help and vignette)
5) Testing
