I don't know if I am off topic here, but I really need some help with a very basic issue.
I am using the function "convert.inp" in the package "RMark" to perform some population estimations for my zoology thesis. The function works perfectly as follows:
Input_file = convert.inp("C:/Desktop/Data", group.df = data.frame(sex=c("YM","AM","F")), covariates = "age", use.comments = FALSE)
Now, I have to add another covariate after "age", as I have a new column in the data, and I cannot figure out how to change the script.
Could someone help me?
