not safe to return vector pointer
Hello All,
I recently upgraded from R-1.1.1 to R-1.2.2.
I have an R function that uses .Call() to
return a list from C code. The C code
has the form:
SEXP function(SEXP var)
{
SEXP rlist ;
PROTECT(rlist = NEW_LIST(3)) ;
VECTOR_PTR(rlist)[0] = NEW_INTEGER(1) ;
VECTOR_PTR(rlist)[1] = NEW_STRING(1) ;
...
UNPROTECT(1) ;
return(rlist) ;
}
When I try to .Call("function",...) from R I get
the following error message:
Error: not safe to return vector po...

Timing of SET_VECTOR_ELT
...R object and "xyz" for the pointer to its contents.)
PROTECT(means2 = allocVector(REALSXP, nvar));
means = REAL(means2);
PROTECT(u2 = allocVector(REALSXP, nvar));
u = REAL(u2);
PROTECT(loglik2 = allocVector(REALSXP, 2));
loglik = REAL(loglik2);
PROTECT(rlist = mknamed(VECSXP, outnames));
Can I assign the individual elements into rlist using SET_VECTOR_ELT at this point, or do
I need to wait until the end of the program, after I've filled in means[i], u[i], etc.? I
likely depends on whether I'm assigning a pointer or a copy.

Rserve and creating a list of lists

unserializes and then adds to an ArrayList<REXP>.
REXPRaw rser = new REXPRaw( target ); //target contains the raw
serialized forms of lattice objects
rconn.assign("temp",rser);
REXP ret = rconn.eval("invisible(unserialize(temp))"); (1)
rexpArr.add(ret);
RList rlist = new RList(rexpArr);
REXPList rl = new REXPList(rlist);
The problem is when I do an assign
rconn.assign("finalresult",rl);

Cannot Compute Box's M (Three Days Trying...)
Hey Duncan,
Hard to debug? That's an understatement. Eyes bleeding....
In any case, I tried all your suggestions. To get "integer" for the final column, I had to change the code to get integers instead of strings.
double[] d1 = ((REXPVector) ((RList) tableRead).get(0)).asDoubles();
double[] d2 = ((REXPVector) ((RList) tableRead).get(1)).asDoubles();
double[] d3 = ((REXPVector) ((RList) tableRead).get(2)).asDoubles();
double[] d4 = ((REXPVector) ((RList) tableRead).get(3)).asDoubles();

Trying to create R dataframe with JRI
.../lib contains jri.dll, JRI.jar and R.dll)
and wrote an simple test application that simply calls a command and
does not do much parameter assignment (except strings and simple
integers) -- all worked fine.
Now I want to feed data as a dataframe to R. I thought I can make
RVector objects, create RList objects from that and create REXP
dataframes from those lists. I found an example here:
http://code.google.com/p/jamsim/source/browse/trunk/JAMSIM/src/org/jamsim/r/RInterfaceHL.java?spec=svn52&r=52

RList rlist = new RList(vectors.size(), true);

How to create a table structure in Java code?
Thanks! I just figured it out (thanks to "Beyond Compare") and was coming here to post back.
The boxM test doesn't work with that (now, finally working) REXP structure, but I probably now need to create a table or something and parse that structure.
So much fun! :)
Thanks again.

Total least squares linear regression
Dear all,
After a thorough research, I still find myself unable to find a function
that does linear regression of 2 vectors of data using the "total least
squares", also called "orthogonal regression" (see :
http://en.wikipedia.org/wiki/Total_least_squares) instead of the
"ordinary least squares" method. Indeed, the "lm" function has a

How to sum values across multiple variables using a wildcard?
I have a dataframe called "data" with 5 records (in rows) each of
which has been scored on each of many variables (in columns).
Five of the variables are named var1, var2, var3, var4, var5 using
headers. The other variables are named using other conventions.
I can create a new variable called var6 with the value 15 for each
record with this code:
> var6=var1+var2+var3+var4+var5
