Dear R-lister, is there any function for Meta Analysis in R? (like homogeneity an, risk differences, relative riskm amd odds ratios? Many thanks, Edwin

Hi, I am looking for C/C++ codes for computing generalized inverse of a matrix. Can anyone help me in this regard? Thanks, Mahbub.

...compiler- and CPU-specific." Is there a listing for the error codes from Lapack routine 'dsyevr'? Especially I am interested about the meaning and handling of error codes 1 and 2. In Lapack.c I only see the reference to the variable info in certain Fortran code: F77_CALL(dsyevr)(jobv, range, uplo, &n, rx, &n, &vl, &vu, &il, &iu, &abstol, &m, rvalues, rz, &n, isuppz, &tmp, &lwork, &itmp, &liwork, &info); if (info != 0) error(_("error code %d from Lapack routine '%s'"), info, "dsyevr")...

Using the 64-bit Solaris compilers make check dumps core in La_rs at 73 F77_CALL(dsyev)(jobv, uplo, &n, rx, &n, rvalues, work, &lwork, &info); I can't reproduce it easily, but example(eigen) occasionally stops with Error: abs(sm - V %*% diag(lam) %*% t(V)) < 60 * Meps is not TRUE which might be connected. The tiny rounding errors in example(eigen) aren't const...

...2: ld returned 1 exit status specifically from the error I understand that error occurs in the link to La_svd which is defined in the first couple of lines in the code: #include <math.h> #include <R.h> #include <Rinternals.h> #include <Rmath.h> SEXP La_svd(SEXP jobu, SEXP jobv, SEXP x, SEXP s, SEXP u, SEXP v, SEXP method); Any ideas?

Hello, I'm using the eclat function of the arules package (1.0-6) for the identification of frequent itemsets. I need the tidLists, but if I set in the function tidLists=TRUE R crashes (Windows XP Professional SP3, 32 bit, R version 2.12.1 (2010-12-16), reproducible on two different computers) with two different error messages or non at all. Minimum examples are: library(arules)
