Hello!

I am a beginner to R, RStudio, and any statistics really, but I have managed to do some analyses (Cox-models and Mixed linear models) that I am now trying to write up in summarizing tables for a report. In my output, the variables (e.g. "Breed" or "Treatment") get a number after it (e.g. "Breed1", "Breed2", "Treatment1" etc). How do I know which breed in my data frame "Breed1" refers to?

For each variable, the output also leaves out the numbers for one level. E.g. Breed3 is missing and Treatment2 as well. I feel like these should be included in my report - how do I get them?

Thanks in advance!
