Hello again,
Thank you for looking over my issue and sorry for not giving reproducible
code. I guess assumed that I was doing something obviously wrong but just
didn't see it.
I did add an entry for bigmemory (and Rcpp) in the DESCRIPTION file for
both the Depends and LinkingTo fields.
Here is an R function and a cpp function that I'm running into the same
problems with when I try to build the package in RStudio with
"build&reload". Please let me know if there is a better format for me to
put it in.
loopWriterR <- function() {
require(bigmemory)
A <- matrix(0, 6, 1)
bigA <- as.big.matrix(A)
print(head(bigA))
loopWriterCpp(bigA@address)
head(bigA)
}
// [[Rcpp::depends(bigmemory)]]
#include <Rcpp.h>
#include <bigmemory/MatrixAccessor.hpp>
// [[Rcpp::export]]
void loopWriterCpp(Rcpp::XPtr<BigMatrix> pA) {
MatrixAccessor<double> A(*pA);
for(int i = 0; i < 6; i++) {
A[0][i] = i;
}
}
Here is the output from the build&reload attempt
==> Rcpp::compileAttributes()
bigmemory >= 4.0 is a major revision since 3.1.2; please see package
biganalytics and http://www.bigmemory.org for more information.
==> Rcmd.exe INSTALL --no-multiarch RcppbigmemTest

}
It seems to me that the automatically generated RcppExports.cpp file needs
to include the bigmemory headers, but it is not.
I also tried putting the bigmemory headers into the package's inst/include
directory and added a flag (PKG_CPPFLAGS += -I../inst/include) for it in
the Makevars files, but this didn't seem to have any effect.
Thanks again for your time,
Alex
