Dear S-Plus users,
let me ask you two questions.
1.
Suppose that
G is a square matrix of dimension (n,n);
FTOT is a vector of length n;
V is a number.
I wrote a procedure where at each step ( starting from 2 to N, the length of
the timeseries Y, and giving the initial step where it is required )
where, according to the calculations below reported,
W and COV are arrays of matrices, each matrix a square matrix of simension
(n,n);
m is an array of vectors;
R is a square matrix of dimension (n,n);
Q is a matrix of dimension (1,n);
A,a,e and f are vectors of dimension n.
W[k, , ] <- (1/d - 1) * G %*% COV[k - 1, , ] %*% t(G)
R[k] <- G %*% COV[k - 1, , ] %*% t(G) +W[k, , ]
Q[k] <- drop(t(FTOT) * R[k] * FTOT) + V
A[k] <- (R[k] * FTOT * 1)/Q[k]
a[k] <- G * m[k - 1]
e[k] <- Y[k] - t(FTOT) * a[k]
m[k, , ] <- a[k] + A[k] * e[k]
f[k] <- drop(t(FTOT) * a[k])
COV[k, , ] <- R[k] - A[k] * Q[k] * t(A[k])
At the end of the calculations, I get a warning message for each of the
previous components and at each step:
" Replacement length not a multiple of number of elements to replace "
What does it mean ? How can I solve these warning messages?
2.
How can I view all the calculations defined inside a function written by
myself ( not only the final result, but all the steps which brought to this
result ) ?
thanks for your help an support
Stefano
