Modulus Bug (PR#7409)
R Developers, 1000000000000000000 %% 11 [1] -32 I now understand that integers cannot be larger than .Machine$integer.max, but because the above produces a result than is patently wrong instead of an error, I'm reporting this as a bug. Thank you for the incredible contributions all of you have made in developing the R platform. Best, Robert Robert McGehee Geode Capital Management, LLC 53

update on dnbinom with large "size"

bug in modulus operator %% (PR#7852)
The following can't be right, first rw2010: > 1 %% 0.001 [1] 0.001 Then rw2001: > 1 %% 0.001 [1] -2.081668e-17 > and the last seems about right. -- Kjetil Halvorsen.

solve computationally singular
Hi uRsers, when inverting a 2 by 2 matrix using solve, I encountered a error message: solve.default(sigma, tol = 1e-07) : system is computationally singular: reciprocal condition number = 1.7671e-017 and then I test the determinant of this matrix: 6.341393e-06. In my program, I have a condition block that whether a matrix is invertible like this: if(det(sigma)<1e-7) return NULL;

No access check deleting printer drivers
Hello list! On all my samba installations (3.0.20b) I can delete all unused printer drivers with rpcclient regardless which user name or password i use. Is this a general feature or might it depend on my settings? Thanks, Martin -- Martin Zielinski mz@seh.de Software Development SEH Computertechnik GmbH www.seh.de
