Dataset search and Analysis using R
For this, you need to find a dataset that contains at least 100 observations. There are a variety of repositories on the internet that contain large data sets. If you’re totally stuck, try https://data.world/
Once you have identified your dataset, determine an interesting plot you can make from it. This can be any kind of chart you want (scatter, line, pie, etc) and can be built using base R or ggplot2 as you prefer.
Now build an R Markdown document with parameters that can be used to generate a report from your dataset and can be customized by setting the parameters. This will follow the same basic approach for the beach water quality example.
So for instance, the parameters might be a start date and an end date and the plot would be limited to that subset. Or they might be a state or a region that is in the data file and plots data for that state.
