This is a code repository for scripts, which generate frequently used plots on macroeconomic topics based only on publicly available data. The intention is to support knowledge sharing and save programming time.
The repository is platform agnostic, though R and Python code would
be preferred.
An overview of available charts can be found in subfolder
figures.
At some point at work you start to lose track of the charts you have made over the years. You might need to update some charts very regularly and know where to find your highly optimized code. However, there are other charts, which you know you made some years ago, but you cannot find the code anymore. So you start creating a code repository. But how should you organize it?
- By topic? But some charts are used for multiple topics. For example, macroeconomic overviews as well as real estate factsheets might use visualisations of house prices. So where to you put the code for those charts, unless you want to duplicate it?
- By data source? But how do you find all charts used for a specific topic, if you are not aware of all the relevant data sources?
In this repository, I propose tags embedded in the first line of a script. Those tags can be searched and no further structuring of the scripts is necessary. This ensures that the code for one chart is only included once and thematic overlaps are possible.
- Create a local copy of this repository and open the project.
- You can use the following code to search the list of tags for a specific topic
# Specify the topics you are interested in
tags <- c("rre")
# Load list of tags and associated scripts
tagindex <- read.csv("tagindex.csv")
result <- NULL
for (i in tags) {
temp <- dplyr::filter(tagindex, tag == i)
result <- dplyr::bind_rows(result, temp)
}
# Show relevant files
result## tag file
## 1 rre bank_credit_growth_by_sector_line_chart.R
## 2 rre bank_credit_new_by_sector.R
## 3 rre bank_credit_stock_composition.R
## 4 rre bank_household_rre_credit_growth_line_chart.R
## 5 rre bank_interest_rates.R
## 6 rre rre_price_growth_for_eu_countries.R
## 7 rre rre_rent_growth_for_eu_countries.R
- Use the code in the R-files to make your own chart
- Add code for a single plot in a new R script in the folder
scripts. - Save the resulting chart in a png file in folder
figures. The file should have the same name as the R script. - Tag the code using just a comment in the first (!) line of the new script.
- Update the index using the following lines
source("functions/update_index.R")
