Hola buenas noches, tengo un problema bastante gordo. ¿A alguno le ha dejado de funcionar las funciones pamer.fnc y mcp.fnc con la nueva versión de R? La semana pasada formatee el ordenador y ahora scripts antiguos no funcionan. La cuestión es que me precupa que no funcione el ejemplo de tutorial del autor. Os dejo un script que debería de funcionar y no lo hace

Dear R People: I have a data set with EEG data. There are 128 measurements per second for 16 locations. What is the best way to handle these series, please? Thanks, Erin -- Erin Hodgess Associate Professor Department of Computer and Mathematical Sciences University of Houston - Downtown mailto: erinm.hodgess@gmail.com [[alternative HTML version deleted]]

Hi everybody, I'm fairly new to survival analysis with R and have some questions how to apply and interpret the coxph and related functions: I have time-dependent covariates with several measurements per subject with constant delta t. The covariates change in each time step. I fitted the following model: fit <- coxph(Surv(start, stop, event) ~ ratePO + rateC + BLamp + BLP80 +

I was just playing around with the R-streams package, reading in some data from an old experiment we did here, and was again amazed by the flexibility of the R environment. The eaze with wich I was able to generate simple plots of my EEG data made me wonder if someone tried to implement an ERP package. For the non-cognitive scientists ou there: EEG is electrical activity measured from the scalp

Hello everyone, I've conducted a Type III repeated-measures ANOVA using Anova() from the car package, based on the suggestions at http://blog.gribblelab.org/2009/03/09/repeated-measures-anova-using-r/(option 3) and http://languagescience.umd.edu/wiki/EEG#ERP_ANOVA_in_R. My ANOVA has two factors: Condition (3 levels) and Region (6 levels) and their interaction. Below is code to run the Anova

Responsibilities include all phases of data analysis from processing of raw imaging

Hello everybody, I am wondering if it is possible to create a gui to plot a time series that is very big, it's an EEG signal of 20mins. What I would like to do is plot the first 5mins, then have a button on the gui that plots the next 5mins when pushed. Is it possible? Thanks in advance ! Gael.

Hello everyone, This is my first time posting to the list, thanks in advance. I am calculating the smoothed periodogram for the residuals of an AR model that I fit to EEG data. The autocorrelation plot of the residuals shows the series is now approximately white (i.e. ACF = 1 at lag 0, and close to 0 for all other lags). I would like to show that the spectrum of the series is also

Dear List: I just successfully installed R 2.8.0 (under Windows XP SP2, 1GB RAM) and wanted to run update.packages. When I first called chooseCRANmirror I obtained the following error message: ---------------- > chooseCRANmirror() Warning message: In open.connection(con, "r") : kann nicht mit 'cran.r-project.org' auf Port 80 verbinden -------------------- What should I do?

Dear list members, I have been using filled.contour in order to plot EEG data. For the colors, I used a conventional ramp from blue to red (blue - green - yellow - red), and 100 color levels to make the plot looking smooth: (...) color.palette = colorRampPalette(c('blue','green', 'yellow','red'), space='rgb'), nlevels = 100 (...) My problem ist that

Dear R users, I m quite a novice in using R for factor analysis and I would need some help to choose the right function. I have a contingency table and I would like to perform a Correspondence analysis on this table, followed by a hirarchical clustering of my variables projected in on the first principal components. Here are my question : - what is the more appropriate function to do so ...

I think I might be mad to include that many mailing lists in this patchset... As I explained in [PATCH 1/5], fstests covers more and more fs testing thing, so we always get help from fs specific mailing list, due to they learn about their features and bugs more. Besides that, some folks help to review patches (relevant with them) more often. So I'd like to bring in the similar way of

Hi I hope this is going to the right place. I am trying to write a program which uses KernSmooth library to estimate mutual information between two time series at various different lags. At the moment it’s producing negative values, which is supposed to be impossible (something is fishy). I am summing across one row of the matrix to get p(value is in bin x) and summing across the columns to get

I have a time series of data from an electroencephalogram (EEG). I wish to filter the data to get rid of 50Hz mains 'hum'. I have 'designed' a combination bandpass and notch filter using a web- site. The site returns the filter in "ANSI C" source code. It is:- /* Digital filter designed by mkfilter/mkshape/gencode A.J. Fisher Command line:

Hello ... I tried to generate .fig figures with R, using the xfig() function ...When I open the figures using xfig software under linux ... the foreground color change strangely ... whereas when I display the same figure in R or when I saved it in using postscript() function there is no problem. Any idea about the behavior of the colors when using xfig ?? Thanks in advance Christophe Grova
