These Tutorials introduce the most important features of phenoptr.

For examples showing aggregation across multiple inForm fields and multiple slides, see the Tutorials in the phenoptrExamples package.

### Learning R

R is a powerful and popular environment for data manipulation and statistical analysis. Many learning resources are available online.

phenoptr is designed to work in harmony with packages in the tidyverse.

• A tibble (also known as data_frame) is the preferred representation of tabular data.
• dplyr, purrr and the pipe operator (%>%) are used extensively in package code and examples.

If you’d like to learn more about the tidyverse packages, a good place to start is Garrett Grolemund and Hadley Wickham’s book, available free online at R for data science. If you are new to R, the book’s Introduction will help you get started.
