Translating a basic Python script into R

Hi,

<snip>
I don't see any nested conditions in the python code... A direct
translation in R looks almost the same, except that you need to group
using parentheses and brackets instead of whitespace, and there is no
+= in R (at least not that I'm aware of). Making those changes gives

   stock = 50
   time = 1
   inflow_a = 0
   inflow_b = 5
   outflow = 5
   x = stock
   y = time

   print ("Model of inflow and outflow rates of water")
   print ("version 3")

   print (stock)
   while (time <= 9) {

       stock = (stock - outflow) + inflow_a
       time = time + 1
       y = c(y, time)
       x = c(x, stock)
       print (stock)
       if (stock == 30) {
           print ("Faucet turned on")
       }
   }

   while (time >= 6 & time <= 9) {
       stock = (stock - outflow) + inflow_b
       time = time + 1
       y = c(y, time)
       x = c(x, stock)
       print (stock)
   }
       sprintf("Volume in tub stabilises at %d gallons over %d
minutes", stock, time)
       print (x)
       print (y)

I'm sure that there must be some very elegant way to do this, but I cannot
find out how to do so in any of the books I have, nor do my web searches
throw back anything useful (I suspect that I'm not phrasing the question
properly).

In both python and R you can of course use if/else instead of the two
separate while loops. An R version is

   stock = 50
   time = 1
   inflow_a = 0
   inflow_b = 5
   outflow = 5
   x = stock
   y = time

   print ("Model of inflow and outflow rates of water")
   print ("version 3\n")


   print (stock)
   while (time <= 9) {
       if(time <= 5) {
           stock = (stock - outflow) + inflow_a
       } else {
           stock = (stock - outflow) + inflow_b
       }
       time = time + 1
       y = c(y, time)
       x = c(x, stock)
       print (stock)
       if (stock == 30) {
           print ("Faucet turned on")
       }
   }

   sprintf("Volume in tub stabilises at %d gallons over %d minutes", stock, time)
   print (x)
   print (y)
   plot(y, x)

Can someone please offer a few suggestions about ways that I could translate
the Python script into R so that I can then run a plot as well?

You can plot in python, e.g.,

   from matplotlib.pyplot import *
   plot(y, x)
   show()

Best,
