Hi, I have been trying to do numerical differentiation using R. I found some old S code using Richardson Extrapolation which I managed to get to work. I am posting it here in case anyone needs it. ######################################################################## richardson.grad <- function(func, x, d=0.01, eps=1e-4, r=6, show=F){ # This function calculates a numerical approximation of the...

Hi there, I have a function which has a variable called show as an input: richardson.grad <- function(func, x, d=0.01, eps=1e-4, r=6, show=F){ # do some things if(show) { cat("\n","first order approximations", "\n") print(a.mtr, 12) } #do more things and return } The show variable is being used as a flag to show int...

Hi, I''ve been using puppet for about a week and a half now, and it''s definitely making my life a lot easier. I''m using 0.24.1 and I''ve run into a small snag. I''m trying to write some code to make sure user home directories exist for users in LDAP. I''m trying to get their uid, gid and home directory from getent with something like: $uid =

...g is not handled correctly. Compare this output with that of: barplot(as.matrix(data), beside=TRUE) Shouldn't the plots look the same except in the beside=FALSE scenario the constituent bars should not be juxtaposed but instead are one on top of the other? Thanks for any advice! Murray Richardson

...server acting as the PRI gateway, the CID name is fine. 1. in the cisco, does anyone know what the command is to set a CID Name for all outbound VoIP calls? 2. is this a bug in Asterisk that will not inject CID name in a channel if it doesn't have CID name coming in first?

Hey Nicolas, That did it. I ran that export command you suggested, then launched *, everything worked fine. I'm still looking for info on what that command actually does. Can you shed some light please? Thanks.

Hi All We're getting to the point where we need to start increasing capacity on our asterisk servers. I've had a look at the DUNDi J Richardson white paper and it seems pretty straight forward. My question is have any of you implemented this solution in a production environment? Regards Ish -- Ishfaq Malik Software Developer PackNet Ltd Office: 0161 660 3062

Is there any way to change the orientation of the labels on the end of the dendrograms to horizontal rather than vertical?

...;m interested in putting together a new-user tutorial about DUNDi configuration and setup. There is a lot of great information, setup guides already but the feedback I get is that the current examples are a bit complicated to follow for new users. Your feedback is appreciated. Thanks.

I'm trying to use multiple plotting colors in my code. My first "ifelse" statement successfully does what I want. However, now I want anything less than -4.5 to be green and the rest black. I want another "col" argument but can only use one. How could I go about getting separate colors for anything above 4.5 and less than -4.5? plot(three, type="h",

Hi, Suppose I have an arbitrary function: arbfun<-function(x) {...} Is there a robust implementation of a numerical derivative routine in R which I can use to take it's derivative ? Something a bit more than simple division by delta of the difference of evaluating the function at x and x+delta... Perhaps there is a way to do this using D or deriv but I could not figure it out.

I had the same problem yesterday. I thought it might have been a realtime problem. Guess not.
