[R] Warning message when starting RStudio

Hi list Recently, when starting up RStudio, the following warning is being displayed: "Error in tools:::httpdPort <= 0L : comparison (4) is possible only for atomic and list types" I think that this is specific to RStudio because starting R in a terminal window doesn't produce this message.

[R] Translating a basic Python script into R

Hi I am attempting to translate some of the models that Donella Meadows wrote about in her book "Thinking in systems" into code. Originally, I had wanted to do this in Python, but thought that it would be fun to see if it is feasible to do so in R, especially given the plotting capacity of R.
