Hi,
This following function works correctly. However, I would like to improve
it by adding to the table of result the titles of columns and rows. I
prefer to define vector column by : D = (Dj = debit[j] ,
j=1:length(debit)) and vector row by: J = (Ji = time [ i ], i = 1:
length(time))
Thank for your help

forage <- function (time, debit, n,ind)
{
pop <- 16867*(1.025^n)
bes <- pop*ind
requis <- 1.2*ind*pop
#906.83
n <- length(time)
m <- length(debit)
result <- matrix(ncol = m, nrow = n);
for (i in 1:n)
{
for(j in 1:m)
{
result[i,j] <- (time[i]*debit[j]) - requis;
}
}
#result;
round(result,2)
#round(rbind(pop = pop,bes = bes,requis = requis), 2)
}
forage (time <- seq( 10,24, by = 2),
debit <- c( seq(8.17, 51.43, by = 8.57), 55, 60),20, 0.035)
