Failure acknowledgement time
Hi, I've noticed that if I disconnect or reconnect a phone from the net, Asterisk take long time to realize that (even more then 10 minutes). Is there a way to reduce this time, working on the configuration files? Thank you. silvia ------------------------------------------------------ Passa a Infostrada.

for loops
Hello everybody I'm very new at using R so probably this is a very stupid question. I have a matrix of "p" columns and I have to calculate for each of them the "two sample t-statistic" and p-value and to save the results into two different vectors. I have divided my matrix into two submatrices: submatrix A containing the first "n1" rows (p columns) and submatrix B

Reformulated matrices dimensions limitation problem
First I wanted to thank both Marc Schwartz Greg Snow and for their reply. Then I needed to add a level of complexity to the problem. I would be able to create the biggest possible matrix. In other way does it exist a method to ask smthing like the following : max number of rows for a matrix if column=x?

optional fields in function declarations; Solved
thank you to both Adaikalavan and Patrick. on the basis of Adaikalavan example this is an example that point out my problems. >log_raise=function(num, exp, base){return(log(num^exp,base))} I would like to have optional fields, so some settings to be default parameters; if I declare the function as above the operator must of course input all the variables. Finally I could fix as follow.

access denied to shares on samba 3
Hi, I have samba-3.0.23d-1tr on a trustix 3.0 system. This samba was joined to a win 2k3 domain and it works perfect for lot of months. Now I can access only to tmp share, and samba server is sometimes slow to expose all shares. If I launch wbinfo ?u or wbinfo ?g, I still see the users/group from win2k3 server, but in the log of my winxp client (whose name is Euro15), I see: [2006/12/27

matrices dimensions limitation
Hello, I have several questions around matrices size limitation: can i create a matrix with 700000 rows? does it depends on the number of columns? if so can Is there a way to ask to R, given the number of columns, the max number of rows I can have? I need in fact to do regression prediction on a huge matrix (700000x1000)ca. ... I will probably have to decompose it on several

Combine vectors in order to form matrixes with combn
Hello! I've a problem with the combn function and a set of vector. I would like to make a simple combination where, instead of scalars, i would like to combine vector, in order to form matrixes. In other words, i have nineteen 6-items vectors (for example coef1-coef19), that i would like to combine in n!/k!(n-k)! 6x6 matrixes. I tried with a code like this mma <-
