Difficulty in writing R code for one pool dynamic model
...will be fed by flux "inA" at a rate of 5 units per hour anddrained by flux "outA" at a rate of 20% per hour. At time 0, A has 5units. At time 30, what is the pool size of A (rounded to 1 decimal)? In theanswer sheet provide the value of pool could be (23.8, 24.8, 25.0 or 24.7). Thevalue I got does not correspond to any of the choices given above. ?I don't know where I got it wrong.?
Below is the Ro code I tried to estimate thepool size of A at time 30.
#Step 1: Specify time?
Tstart <- 1
Tstop <- 30
Tstep <- 1
#Step 2: Set variables corresponding to pools

order complex aggregation results in 'calculate'

''calculate'' (from ActiveRecord::Calculations::ClassMethod)?

which generates the following (Postgres) query:
SELECT avg(subject) AS avg_subject FROM logevents ORDER BY
avg_subject
This works, but the :order option depends on what I think are
