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?
Thank you

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.

Duplicated non contiguous element in a list
Hello,
Given a vector I would like to rapidly identify duplicated non contiguous elements.
Given for example
c(1, 1, 2, 3, 2, 4, 5, 6, 4)
I would like to get:
FALSE FALSE TRUE FALSE TRUE TRUE FALSE FALSE TRUE
In fact I need to check this on the columns of a matrix!
I can do that of couse with loops but is there any function already available?
Thanks

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

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.

Inverse of one function
Dear Partecipants to the list,
I am searching a R function, which can calculate the inverse of one real value function.
Does it exists a R code in order to make it?
Many thanks for any kind of help and for Your availability.

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:

Diagonal Submatrices Extraction
Yes you are right ... an example is mandatory.
So ... I have a matrix of 0 with just a single 1 per row and per column
I need to extract all maximal 'diagonal' submatrices
Let's say I have the following matrix
A B C D E
a 0 1 0 0 0
b 1 0 0 0 0
c 0 0 1 0 0
d 0 0 0 1 0
e 0 0 0 0 1
well I would like to get, for this example, the two following submatrices

Realtime+IAX2 and RSA
Anyone had Realtime working with IAX2 and RSA authentication to connect two
PBXs, please? It seems that inkeys/outkey fields are not read at all and
the following warning is logged when dialing:
Jun 2 02:41:36 WARNING[6299] chan_iax2.c: I don't know how to authenticate
******** to XXX.XXX.XXX.XXX
Using iax.conf it perfectly works. Maybe a bug in Realtime?
TIA,

How to quickly replace ',' with '|' in dialplans?
Finally I decided to rewrite my dialplans according to the right sintax,
that is
exten => someexten,priority,application(arg1,arg2,...)
should be
exten => someexten,priority,application,arg1|arg2...
Isn't there anybody skilled enough in regular expressions that could write
a quick Search 'n' Replace vi command, please?
TIA,
