This repo contains the data for the Latin American Public Opinion Project. With this information, we aim to create web-based, interactive, self-guided analytics.
These are the steps you should take to begin using this repo.
You will need the current version of RStudio to run this code.
The code and text were written in an R Notebook. This is an R Markdown file (.rmd) that runs interactively. It does not require any additional installation, as it is a built-in function in R Studio. For an in-depth tutorial, visit this R Notebook Guide. There are also cheat sheets available for how to use R Markdown.
You will need to download all of the merged files that exist for each country individually from the LAPOP Datasets. Currently, you need to download the 2016/17 files separately, but in the future there may be a more recent merged file that includes these years.
In order to run this code, you will also need to install the following packages using install.packages():
Finally, you will need the excel files provided by the LAPOP organization that contains the current list of categories and questions to be visualized. The excel file should then be converted to .csv for use in RStudio.
You can find these files above. They are named as follows:
- "LAPOP categories unfactored.csv"
- "Lapop Categories factored.csv"
- "updated factor questions.csv"
- "updated unfactor questions.csv"
These files will need to be placed into the working directory of your project in RStudio.
For the final visualizations, you will need to have Tableau Public installed on your machine. There is a login that belongs to LAPOP, and this is the one you should use to save your visualizations to.
