I am seeking assistance in translating the following JavaScript code into R and displaying the values at each iteration:
r=4
q=0.02
V=0.01;
S=0.1;
U=0.89;
for(i<200){
i++;
v = V;
s = S;
u = U;
V = r*v*s;
S = s - r*v*s + q*u;
U = 1 - v - s;
}If you have expertise in both languages, your help would be greatly appreciated. Thank you!
Here is my preferred method to accomplish this task using R:
n = 150
r = 3
q = 0.05
V = numeric(n)
S = numeric(n)
U = numeric(n)
V[1] = 0.02
S[1] = 0.15
U[1] = 0.83
for (i in 2:n) {
V[i] = r * V[i-1] * S[i-1]
S[i] = S[i-1] - r * V[i-1] * S[i-1] + q * U[i-1]
U[i] = 1 - V[i] - S[i]
}
result = cbind(V, S, U)
Each cycle's outcome is stored in rows of result. Please note that the calculation for U[i] differs here from your initial input, though it aligns with the equation you provided in the image.
