Dear R-list, It is not uncommon for laboratory equipment (e.g. spectrophotometers) to have a linear response in a certain interval and then go into saturation. I wonder if there is an R-function that models this; for instance by estimating the breakpoint and fitting a line below the breakpoint and a constant above. Best regards Thomas Poulsen -- Thomas Poulsen Research Scientist. PhD,

Dear list, I would like to call a Kerberos-authenticated web-service from within R. Curl can do it: $ curl --negotiate -u : "http://my.web.service/" so I would expect that RCurl also has the capability, but I have not been able to find the correct options to set. listCurlOptions() does not return anything with negotiate, and searching the source of RCurl, the only thing I found was

The Register is carrying a article written by Kevin Poulsen of Securtiy Focus, calling asterisk "..the most powerful tool for manipulating and accessing CPN data.." > http://www.theregister.co.uk/2004/07/07/hackers_gut_voip/ I hope NuFone doesn't drop asterisk-set-able callerid's after this article; i've been wanting that feature from voicepluse for a long time.

Hello R-Users, I am trying to label points on an xYplot. I can label the points, but then I lose the error bars. I suspect that I should be using panel.xYplot rather than panel.xyplot, but that didn't work either... Can anybody help me out? Example code is below. First xYplot has error bars, second tries to label the points and the bars disappear. Thanks, John a=c(1:4)

Hi All- I am running into a small problem trying to implement voicemail Directory(). I'm sure it is a simple thing, but I can't figure out where the problem lies. I can get into the directory without a problem and can look up users by their last names, however I hit a snag when asterisk says "if this is the person you are looking for press 1 now". When I hit 1, the attendant

Hello, I am trying to run a logistic regression with random effects on proportional data in glmmBUGS. I am a newcomer to this package, and wondered if anyone could help me specify the model correctly. I am trying to specify the response variable, /yseed/, as # of successes out of total observations... but I suspect that given the error below, that is not correct. Also, Newsect should be a

Hi, all. I'm trying to automate some regression operations in R leaving the possibility to modify the predictors in the regression. For example, I have saved in a list the results and then exported as a txt file, in which we can modify the predictors, putting for example lm(y~x^2) instead of having lm(y~x) as in the original model. Now, I need to import in R the txt file as a list to

Hello R-users, I have code that gives me the important variables from an analysis. I need to input these variables into a different analysis. To do this, I need to modify them slightly... 1) remove all numbers at the end of the variables, 2) remove all periods. I tried to do it with the awkward code below. It works to remove all the numbers, but when I try to remove the period everything

Hello, I want to build a function to call up a column of a data.frame by the names of the columns. I have column names that are sequentially named (col1, col2, etc.). How do I change a character expression into something that will be understood as a data.frame column. For example: example<-data.frame(cbind(col1=1:10, col2=21:30, col3=41:50)) call.fun<-function(t){

Hi all. I am new to the list and new to asterisk. I have asterisk installed and running. I am using it as a voicemail server only. What I would like to do is send users to a general mailbox that will be addressed as <companyname>@asterisk and give them the option to wait for the tone and leave a message, or press 9 to dial by name. My questions are: 1. What is the best way to do

Hello, I am trying to plot a curve over points plotted with se's in xYplot (see example below). I can get Figure 1 below to plot the data with error. However, I keep getting a the error message "Error using packet 1 object "y" not found" Can anyone see what I am doing wrong? Thanks! John ------------------------------- a=0.002; b=31.7; c=0.51

Newbee here.... I would like to play around with Asterisk a little. First, I need to prepare a server with FreeBSD. It's a PII 433mHz/256mb box. Good enough? Then install Asterisk. I have a broadband (cable) internet presence. Could I do anything with this connection and Asterisk? Thanks, Rayasterisk --------------------------------- Do you Yahoo!?

I am a newbee to asterisk. I recently installed asterisk@home. Everything went well and my set up is running fine with soft phones, such as kphone and XtenLite. Now, i want to be able to connect my analogue phones to my asterisk pbx box and use it as if i make a regular Phone call (I do have my PSTN gateway account with broadvoice.com and already configured to route through it). I do NOT have a

Hello, I am trying to make a xyplot plot with points that are different symbols. I want to call the symbol type (pch) from a column in my dataframe. Here is a simplified example. In my real example I also have groups, which I have not included here. This example doesn't change the symbols or colors. Any help you can provide would be appreciated. Thanks, John x<-c(1:12)

I ran into a problem today which surprised me, and after two hours of reading and testing I am more confused than ever, so I feel the need for a sanity check. It would be good to have a clear and authoritative article about this somewhere; I thought it would be in either "Using Samba" or in the HOWTO, but I don't see it there. I am using Samba in several installations in homes and

Hello, as a newbee, I'd appreciate some support on regression test setup. Specifically, I am interrested in the feature of tail call optimizations for the ARM v6m targets. This feature currently seems to be completely deactivated at the moment (v6m being based on thumb1 ?!). According to my code-reading, this feature will involve some modifications in epilogue generation. My work on a gcc

Hello everybody, To make all clear; I am newbee in shorewall, but... I''ve tried to connect two computers by Mandrake Connection Sharing facility. (Mandrake 9.1). Briefly, the problem is that after all that auto-configuration activities the network is completely down, just because shorewall. The result of calling `shorewall debug start` by hand is available at the end of the

Hi! I am newbee to R and I am facing the problem in plotting the dedrogram with lot of objects. The lines and labels are overlapped very badly, and writing the graphic to postscript and zooming there is not helping either. I tried cut.dendrogram method, but getting the error that it doesn't exist even though I get the man pages for it. I would not find any solution in web as well, and I
