This is a collaborative project with the aim of tidying and visualising nutritional data. The goal is to develop a simple shiny app to help the user quickly search, compare and visualize nutritional data of single or combined food ingredients.
In order to help manage the development of the Shiny App a checklist with ideas and tasks is available under doc folder: Ideas_list_checklist.md
Test the app here: https://agrou.shinyapps.io/nutrient_pt/
Go through the following instructions to have the whole project locally:
-
To run the app you need to download this project, open the
nutrient_pt.Rprojin RStudio. -
Before running the app you need to create a new subdirectory
data(nutrient_pt/data) and populate the subdirectory with the data that is obtained by runningrunall.Rmdfile, undersrcfolder (see more instructions below in 2. About the data).
Food composition data is publically available and provided by Instituto Nacional de Saúde Dr. Ricardo Jorge (portuguese "National Institute of Health" - INSA): http://portfir.insa.pt/foodcomp/introduction Under INSA's legal requirements, the data should not be used with any commercial intent.
To download the data you can follow these steps:
- Access to "Composição dos alimentos" tab, then select 'Pesquisa de Alimentos' >> 'Download da TCA'
- Save the data
insa_tca.xlsxunder the already opened projectnutrient_pt/dataand run the code chunks from the filerunall.Rmd. This will save the imported, cleaned and transformed datasets into the projectdatasubdirectory.
After following the previous instructions, open the files ui.R, server.R and global.R under src folder in RStudio. You may need to install or load the libraries listed in global.R as well. Then you can click on the >Run App button on the top of the screen.
