I am conducting a complex analysis in R involving the phylogeographic reconstruction of a disease dynamic over time and space. As part of the process, I use the spreadGraphic2 function from the seraphim package to reconstruct spatial polygons for visualization. However, I’ve encountered an issue with this function.

I have multiple dataframes with varying column numbers and many thousands of rows. Every DF has Year and ISO columns. I want to merge all of them into a final DF that has a single Year and ISO columns and unique value column/s that correspond to those from the original DFs. The final output has to go back out in .xlsx format so I’d like to minimize the number of rows which are populated with mostly NA.

I am new to R. I am working with a dataset in R where each patient is identified by a unique subjectid. Each patient has a baseline_date and multiple follow-up dates (fu_date). I want to filter follow-up records for each subjectid that fall within ±120 days of exactly 1 year (365 days) from the baseline_date.
