Cisco IP Communicator with Asterisk/Trixbox
Hi guys, Has anyone had any luck with getting the Cisco IP Communicator working with your Asterisk or primarily, Trixbox installation? I've tried searching the net for information, and found someone said to set it up like the 7970 hard phone, which I have, and I'm just running into the problems with it saying "Error Verifying Config Info". Any and all help is appreciated.

Plotting barplot and scatterplot on same device - x-axis problem
Hi R-users I'm a relative newbie and uses R mostly for graphical purpose. I have a layout problem when plotting a scatterplot and a barplot using par(new=TRUE). The baseline of the x-axis is not positioned equal for the two plotting functions (see picture) and I have been unable to find out how this is changed. http://www.nabble.com/file/p18025066/pic.jpeg I have added the script if this

selecting maximum values
Sorry for disturbing you with another newbie question! I have a data frame about coastal waters quality parameters: for some parameters (e.g. NH3) I have only 1 observation for each sampling station and each sampling date, while in other cases (chlorophyll) I have 1 obs for each meter-depth for each station and date. How can I select only the max chlorophyll value for each station/date? example

Linear Discriminant Analysis error: "Variables appear constant"
Hi R experts, I'm attempting to run Linear Discriminant Analysis using the lda function in the MASS package. I've got around 50 predictor variables and one response variable. My response variable has 5 numeric categories that represent different clusters of fish abundance data (clusters were developed using Bray-Curtis and NMDS), and my predictor variables are environmental variables that

problem with library tseriesChaos
Hi R-Users I need to estimate Lyapunov exponent of my time series. After reading description of all functions available I still don't know how to determine time delay. My time series length is 4200. Is it possible to determine time delay with other function's output or I can choose any random value? Thanks for your help! -- View this message in context:

lm: how to calculate rsquared of the predicted values?
Hi, I've built a linear model using multiple linear regression which leads me a R-squared value of 73.58%. After that, I used this model to predicted some values based on the test data. Now I'm wondering how: 1. can I measure de R-squared value between the predicted(by the model) and real (observed) values.? 2. Measure the RMSE error . Example: suppose my data its below: REAL

Adding a correlation value (like Rsquared) to a 4 parameter logistic fit model.
Hello, In my lab we use a four parameter logistic fit model for our ELISA data (absorbance values). We are currently testing the use of different solvents and need to find a way to add a correlation value (such as an R squared or something similar) so we can test different solvents in making this standard curve. We currently use the drc package and this is our script for the 4 parameter:

Rsquared in summary(lm)
Hello, I'm doing some linear regression: >lm<-lm(osas~alp,data) >summary(lm) However, the Rsquared in the output of summary() is not the same as the "standard" Rsquared calculated by spreadsheets, and outlined in statistical guidebooks, being SSR/SSTO. The output says "multiple Rsquared", but it is no multiple regression... What's the difference? Thanks,

Rsquare from glmmPQL or another GLMM?
Hi, I know that Rsquare in glm or in non-linear models is "wrong", but some people like this. How I make to estimate the Rsquare from a model ajusted with glmmPQL or another GLMM?
