Dear all,
I am trying to use ace on a 446 x 14 Matrix, with two categorical
variables in the first two columns. If I try to run it I get:
> aceiH <- ace (data.mat, resp, cat= 1:length(x.cat))
Error: NAs in foreign function call (arg 3)
There is only one .Fortran call in ace () with the third argument being
x = t(x). Thus I tried to debug ace, i.e. I went through ace until just
before the call to .Fortran. I can play with all the variables in the call
and all seem to be ok, specifically there are no NAs in t(x) but the call
fails also while debugging:
> debug (ace)
> aceiH <- ace (data.mat, resp, cat= 1:length(x.cat))
debugging in: ace(data.mat, resp, cat = 1:length(x.cat))
debug: x <- as.matrix(x)
Browse[1]>
... ## go through ace until before .Fortran call
Browse[1]> table (is.na (t(x)))
FALSE
6244
Browse[1]>
debug: junk <- .Fortran("mace", p = ncol(x), n = nrow(x), x = t(x),
y = y, w = wt, l = l, delrsq = delrsq, ns = ns, tx = tx,
ty = ty, rsq = double(1), ierr = integer(1), m = m, z = z)
Browse[1]> junk
Error: Object "junk" not found
I am trying to find a smaller example that has the same effect so I could
send it to the list but was not successful until now, especially as I do
not really have any idea in what direction to search.
Any pointers or ideas are appreciated. Regards, Lorenz
