search for: _sequence_

Dear all, is there any function to calculate the center of a polygon mass in R? Actually I need to find the best location within polygons to place labels. Thanks for any hint Jens Oehlschl?gel -- COMPUTERBILD 15/03: Premium-e-mail-Dienste im Test\ --------...{{dropped}}

...into objects of their own. Then, I thought, I must check whether a sequence of breaks in the shorter vector occurs in the longer vector, and if so find the indices of that sequence. Here, I think I must have overlooked something... I didn't find an elegant way of finding the indices of a subset _sequence_ of an array... My own solution, the sub.vector-function looks like this: sub.vector <- function(b1, b2) { i <- 0 while(! all(b2[(i+1):(length(b1)+i)] == b1)) { i<-i+1 if(i+length(b1) > length(b2)) return(NULL) } return((i+1):(length(b1)+i)) } Ugly, eh...? :-) Any su...

Hello folks, I'm having trouble configuring Asterisk to play an "invalid extension" message to anyone dialing an undefined extension. First I tried using the 'i' pseudo-extension, but it didn't work at all; searching the wiki I found that page: http://www.voip-info.org/tiki-index.php?page=Asterisk%20i%20extension where it basically says that the 'i'

I implemented it almost literally as you suggest (see below for my extensions.conf file after the modifications). >The above _sequence_ of include statements is maintained for each call. >In other words, if a call does _not_ match entries in 'valid-extensions', >then it proceeds to the next include.
