must .Call C functions return SEXP?
...<- vector("list" ,1e6)
.Call("my_C_function", result.1, result.2, other.input)
My C code looks like this:
SEXP result_v;
result_v = Rf_allocVector(REALSXP, 5);
SET_VECTOR_ELT(result_list_1, k1, result_v);
REAL(result_v)[0] = some_number;
REAL(result_v)[1] = another_number;
/* Also do the same sort of thing for result_list_2. */
return(result_list_1); /* Appears to work ok. */
/* return; */ /* Segfaults. */

sas retain statement in R or fitting differene equations in NLS
...late the expected values of y if
I knew the values of the parameters tau and b.
# but in reality I would like to estimate them.
# code is for illustration of the principles and is not meant to be
functional!!
yaux[1]<-0
b<- a_number # b would have to become estimated by nls or nlme
tau<- another_number # tau would also be estimated in nls or nlme

yaux[t+1] <- yaux[t] + (X1-yaux[t])/tau
yhat[t+1] <- yaux[t+1]*X2[t+1]/(X2[t+1]+b)
}
Now, my problem is that I do not know the values of /tau/ and /b/ and I
would like to estimated them by non-linear regression. This is easy i...

outbound dialing / wait for keypress?
...ically build a
dialplan. i make repeated use of this perl call:
system("asterisk -r -x 'add extension 100,++$i,Dial(Zap/2/[number],15) into local;
to create a dialplan that looks like this:
s,1,Answer
s,2,agi,script.agi
s,3,Goto(local,100,1)
100,1,Dial(Zap/2/[number],15)
100,2,Dial(Zap/2/[another_number],15)
...
so far, so good - if the first number dialed is busy or times out,
it tries dialing the next number, and so on until one is answered at which
point the incoming and outgoing calls are connected.
my problem is how to handle the case where an outbound call is answered
by, say, an answering...
