if value is in vector, perform this function
...possible t values, do this command, else, do this command" if that makes sense. Here's what I have (and it doesn't work):
params = c(1, 0.15, 0.164, 1)
init = c(1.5, 0.05)
t=seq(1,60, by=0.5) #all time values, experiment ran for 60 days
#feeding sequence - every "3.5 days"
feed_days = seq(1,60,by=3.5)
Daphnia <- function(t,x,params){
C_D = x[2];
C_A = 0;
for(t %in% feed_days){
if t == TRUE {
C_A = 1.5
}
else{
C_A = 0
}}
gamma = params[1]; m_D = params[2]; K_q = params[3]; q_max = params[4];
M_D = m_D * C_D
I_A = (C_D * q_max * C_A) / (K_q + C_A)
