Hello List. I have many files of ECG, each one with 7 column and I need only the second column and the name of each ECG. I am doing this but althought I have various days trying this i haven't gotten, so I ask help with this, if somebody cans help me I'll be so thankfully. -----------------------------------------------------...

Dear R help gurus, I have the following problem and I would be delighted if you could help me. >From a large (1500) cohort of patients we have been taking some measurements (ECG measurements, but its not important). The measurements are ordinal in 4 grades (Grade I-IV, grade IV being the most severe form). Every patients has been measured several times (usually once per year). The follow-ups are different for each patient (ranging from days to several years), thus some pat...

Dear all,   I write this message because I have a problem in data importation. I hope that you help me. My data base is in an Excel spreasheet. I import this data base using the following code: library(RODBC) db <- "C:/Users/Axel/Desktop/estimation/data.xls" channel <- odbcConnectExcel(xls.file = db) data <- sqlFetch(channel = channel, sqtable = "Feuil1") data

Hi!! I'm looking for a package in R for time series analysis using wavelets( I'm interested on extractingt information from electrocardiograms with the aim of study the heart rate variability) so i want to know which package is the best for me. I've thinking about using some of those(you can recommend me others,xD): *wavelets: A package of funtions for computing wavelet filters,

Dear R-help members, To whom it may concern, our research group is conducting a study to evaluate the predictive value of 24 hour blood pressure variability. We are looking for an R routine that performs a fast Fourier transform spectral analysis (with an output of the approximation function of the Fourier and estimates the validity of the model for the various harmonics). Thanks Vittorio

I did make it compile after a lot of effort, but it crashed R on

Dear All I would need to generate differences between variates such as nam1<-nam2-nam3 in the following loop: for(i in c("13","26","38")) { for (j in c("HR","PQ","QRS","QT")){ nam1<-paste("d",j,i,sep="") nam2<-paste(j,i,sep=".")

The current development version dies in qbeta() when compiled with egcs -O, egcs 1.0.2 and glibc 2.0.7 (RedHat versions). Since this also kill the F and t distributions, it doesn't exactly do wonders for R's usefulness... Anyone else seeing this or has my setup just gone out of whack? It does look pretty much like a clear compiler bug when inlining math functions (storing temporaries

...great. Last week, I downloaded the binary Ms Windows version. I wanted to test it for my students. Our labs are under Bill Gates. I am not happy but I can do nothing. R worked. But, I could not use the dyn.load command with some dll built with one of the ports of gcc for windows 95/nt (I used the ecgs-mingw32 ports http://www.xraylith.wisc.edu/~khan/software/gnu-win32). The same dll's work with Xlisp-Stat. Then, I rebember something posted by Luke Tierney somewhere about dll's and the Watcom compiler. I took a look to his pages and found out that perhaps the problem is not ecgs but W...

Hi, I'm in dire need of a fast fourier transformation for me stupid biologist, i.e. I have a heartbeat signal and would like to decompose it into pure sin waves, getting three vectors, one containing the frequencies of the sin waves, one the magnitudes and one the phases (that's what I get from my data acquisition software's FFT function). I'd be very much obliged, if someone

HI there guys! Just installed fifa 11 very smoothly on wine 1.3.7 (I use Arch!). Game launches, Kaka loads playing at the start, but when I try to launch a match, the game crashes with the error listed in the subject! You know what could be? Do I have to modify something in winecfg? Thanks in advance!

Dear All, discussing with a statistician of a pharmaceutical company I received this answer about the statistical package that I have planned to use: As R is not a validated software package, we would like to ask if it would rather be possible for you to use SAS, SPSS or another approved statistical software system. Could someone suggest me a 'polite' answer? TIA Giovanni -- dr.

Hi. To begin with, I have a freshly built RedHat Linux 8.0 box running samba 2.2.8a. The kernel version is 2.4.18-14. I downloaded and compiled samba from source. I am using LPRng-3.8.9-6 as my printing system. The attached printer is a Lexmark Z22 printer and it is attached to the parralel port. Problem: For the life of me, I can't get NT type clients, NT4, 2K and XP to print to samba.
