Welcome all, Resources can depend one from each other, and failure of a required resource prevent the dependants from being run. But how to trap these failures and handle them? Is there any way to e.g. set a variable $error_happened to "true" if some promise about the resource couldn''t be kept? Maybe even there is a way to capture the error string? Some

Dear All, Under Debian GNU/Linux La.svd (with method = "dgesdd") sometimes gives the error "Error in La.svd(data, nu = 0, nv = min(nrow, ncol), method = "dgesdd") : LAPACK routine DGESDD gave error code -12" It seems not to depend on the data per se, but on the relationship between numbers of rows and columns. For example, if the number of columns is 100,
