I am working on an update to my package pcaL1. Using win-builder, I
get a note including "Found no calls to 'R_registerRoutines',
'R_useDynamicSymbols'". However, in my submission, I have a file
src/init.c that includes the contents at the bottom of this email to
register .C() routines. Why can't win-builder find the calls to these
functions?
Also, when I include "useDynLib(pcaL1, .registration=TRUE,
.fixes="C_")" in NAMESPACE so that I can refer to the routines as R
objects, I get a warning that the objects C_* are not documented. Is
it okay to ignore this warning? It appears that the package stats
does not document such objects.
The contents of src/init.c:
#include "type.h"
#include <stdlib.h>
#include <R_ext/Rdynload.h>
#include <R_ext/Visibility.h>
void l1pcahp (double *points_XT, int *dataDim, double *threshold,
double *initV, double *PCs);
void l1pcastar (double *points_XT, int *dataDim, int *q, double *PCs);
void l1pca (double *points_XT, int *dataDim, int *q, double
*tolerance, int *iterations, double *initV, double *PCs, double
*Scores);
void l1projection (double *points_XT, int *dataDim, int *q, double
*PCs, double *projPoints, double *alphas);
void pcal1 (double *points_XT, int *dataDim, int *q, double *PCs, int
*initMethod, double *initV);
void pcalp (double *points_XT, int *dataDim, int *q, double *p, double
*PCs, int *initMethod, int *solMethod, double *initV, double *epsilon,
double *lratio);
void sharpel1pca (double *points_XT, int *dataDim, int *q, double
*PCs, double *objectives);
