I conduct database audits for nonprofit clients analyzing data quality and hygiene and historical charitable contribution trends/metrics. I have a standard report (created in PowerPoint and sent to client in PDF) and a recommended/required data layout. I'm looking to expand this product offering by building an automated tool that can quickly and accurately run these reports (about 30-35 different reports in total), ideally through a web interface that clients could log into, upload their data, and receive a report with relatively little direct interaction. The metrics required are not particularly complex, but there are some nuances to them due to the nature of nonprofit clients and how performance is measured. Ensuring data privacy and security are of utmost concern, as is being able to confirm that no data from different clients is intermingled. I am a one-person consultancy and I am not a programmer, but do create these reports myself using Excel and csv files. A copy of the report can be provided.

I am looking for someone to create a code that analyzes and compares X,Y, and Z data for reproducibility and repeatability in the form of a 95% confidence ellipsoid using R code and ggplot. I would like a section of code that “extracts” data about the confidence ellipsoid so I can also analyze and compare that data. I would also like the code to have comments on what each line of code does if possible.
