Hi All, I'm an R programmer that has recently started learning Racket. I decided to start by trying to create a simple age-structured population model. In R, I would initialize a matrix and use nested for loops to move through the elements of the matrix and propagate the population forward through time. For my first attempt in Racket (https://gist.github.com/hinkelman/3ee6115cdd7f0a4c8f1672b7d8df5c27), I used for* to loop through a vector of vectors. The code in that gist doesn't quite work. There is apparently something wrong with how I'm using vector-set! such that "rows" in my vector of vectors are being updated prematurely. I would greatly appreciate it if someone could point out what I'm doing wrong there. I'm also interested in suggestions for alternative approaches because it seems unlikely that I have written this code in idiomatic Racket.
Thanks, Travis P.S. If it is helpful, here is a gist (https://gist.github.com/hinkelman/d5b8414b0c6383057d7846509a724bbf) with the R code that I was trying to write in Racket. -- You received this message because you are subscribed to the Google Groups "Racket Users" group.
