Buenas tardes, Tengo un data frame denominado “trabajadores”, que cubre desde el 1 de enero de 1997 hasta el 30 junio de 1999, con 3 columnas: Identificador (ID), la fecha de entrada en la empresa (ENT) y la fecha de salida (SAL). Deseo localizar aquellos trabajadores que, durante dicho periodo, NO han llegado a pasar un 31 de diciembre y un 1 de enero seguidos (cambio de año) como asalariados

...9;'m missing something really obvious, but huh? Why is it that when I call it with arguments, it doesn''t want any, but when I call it without them, it does? Is it the *type* of argument? But since the parameters are dynamically typed, that makes no sense to me. What am I missing? Chas. Munat Seattle

...onfdefs.h" #include "./tests/fcntl_lock.c" I don't have any idea why it gets a parse error. I actually looked at fcntl.h and everything seems fine (not that I would expect such a library file to have an error). I posted the entire log file at http://www.ccrc.wustl.edu/~chas/config.log if that helps. Thanks, Chas S. chas@ccrc.wustl.edu

Dear All, I have data which contains 14 variables.

...= No create mask = 0600 directory mask = 0700 locking = No The specific error is: machine 127.0.0.1 rejected the session setup. Error was : ERRSRV - ERRbadpw (Bad password - name/password pair in a Tree Connect or Session Setup are invalid.). Failed to change password for chas I was able to set the root password w/o the -r option, but then when I try to reset it with the -r option, it also fails, so I don't think it has to do with the empty password. Can anybody tell me what's up with this, or how I can figure out what the problem is? Thanks, Chas

getnybble() needs to return four bits at a time from every byte. During rle decode, rows are rounded to an integer number of bytes. The rle length needs to be able to hold values > 255.

We recently have upgraded syslinux and have noticed that the boot logo code via boot.txt no longer works. I have a couple patches that get it close to working but I appear to be having trouble with color maps. Is there someone would want to help me finish figuring this out? Any interest in the patches I have to fix the rle decoder?
