hi :smile: i have a short question regarding the ChainLadder package. I found a website with an instruction for the Munich Chain Ladder that is included in the ChainLadder-package. But unfortunately, the data for "MCLpaid" and "MCLincurred" are both presaved and I have no idea how I can change them, because I want to use it for my own data.https://cran.rstudio.com/web/packages/ChainLadder/vignettes/ChainLadder.html#munich-chain-ladder I would be very happy if somebody could help me please and I am sorry if this is a stupid question, but i am not very advanced in working with R.

Many Greetings

Hi there,

The vignette has a short section on how to import triangles stored in an Excel spreadsheet via a CSV file: https://mages.github.io/ChainLadder/articles/ChainLadder.html#importing-triangles-from-external-data-sources

There are many other options to read in your own data. The openxlsx R package is pretty good if your data is stored in Excel workbooks: https://ycphs.github.io/openxlsx/reference/readWorkbook.html

I hope this helps.
