tacApp

The goal of tacApp is to help you analyze changes in the power sector between two time periods. The public source code lives in an R package, and the public application is available online.

Usage

• Go to https://twodii.shinyapps.io/tacApp/.
• Select a parent company and a technology.
• Click “Apply”.

Output

• A summary of the real and virtual change.
• A breakdown of changes as a plot.
• A breakdown of changes as a downloadable table.

A real change is an increase or decrease in the production capacity. A virtual change is a change not in the production capacity but in the ownership of the asset.

Code organization

The app is organized in the same was as an R package. Learn more at https://mastering-shiny.org/scaling-packaging.html.

Data

The data is private and not hosted here. The ultimate source is Asset Resolution. The raw data is first processed in the data-raw/ directory in the private repository at https://github.com/2DegreesInvesting/tacAppPrivateData, then processed further in the data-raw/ directory here. The file names and comments should guide you.

file_names <- list.files("data-raw")
file_names
#> [1] "01_valid_rowids.R" "02_data.R"         "utils.R"          
#> [4] "valid_rowids.txt"

comments <- head(readLines("data-raw/01_valid_rowids.R"))
writeLines(comments)
#> # This script is very slow but for a good reason: To improve the experience of
#> # those who use the tacApp. This process helps expose not all the raw data but
#> # only that which leads to valid results. Without this the user would often get
#> # invalid results. Be patient. On my laptop this script completed in about 3h.
