Dear R helpers
I have two series A and B as given below -
A <- c(2, 2, 1, 3, 7, 3, 3, 1, 14, 7, 31)
B <- c(0.0728,0.9538,4.0140,0.0020,2.5593,0.1620,2.513,0.3798, .0033,0.2282,
0.1614)
I need to calculate the total in dataset B corresponding to the numbers in
dataset A i.e. for no 1 in A, I need the total as 4.0140+0.3798 (as 1 is
repeated twice)
for no 2, I need the total as 0.0728+0.9538 (as 2 is also repeated tqice and so
on)
Thus for no 31 in A, I should get only 0.1614.
I have written the R code but its not working. My code is as follows,
# --------------------------------------
D <- array()
i = 1
for (i in 1:max(A))
{
D[i] = 0
i = i + 1
}
# _____________________________________
T <- array()
k = 1
m = 1
for (k in 1:max(A))
{
for (m in 1:max(A))
{
if (D[m] == k)
T[k] = T[m] + B[m]
else
T[k] = T[m] + 0
m = m + 1
}
k = k + 1
}
# ---------------------------------------------------------------------
Please correct me. I think I have messed up with the loops but not able to
understand where. Please guide me.
Thanking in advance
