Hi all, I have a large data.frame, 1530 observation with 6 columns. I want to merge a 7th column, a transformation of the response variable (hospital admissions), namely trans<-sqrt(copd$admissions+0.25) trans<-data.frame(trans) And now when I do copd2<-merge(copd,trans) (copd being my original data.frame), R either crashes or is taking an extremely long time to do the computation. I had expected the computation to be done almost instantly as I have done similar things in R...

...f this question has been answered previously, however searching of the archives and the internet generally has not yielded any results. I am looking in to the effects of summer weather conditions (temperature, humidity etc), on the incidences of a breathing disorder brought on through smoking (COPD). I am fairly new to R and completely new to the idea of writing R scripts, subsetting dataframes etc. I am working on a 12 week summer placement at the Met Office, UK, having just finished my second year of a mathematics course at university. Basically I have data between January 1 1997 and D...

...ows extrapolation of preclinical to clinical and epidemiological findings. Existing (pre-) clinical data will be analysed with advanced data analysis software tools such as NONMEM and R. We are looking for two highly motivated scientists (PhD degree) to: 1) investigate disease models in COPD. The COPD project is part of the disease progression working group which consist of two PhD students and two post-doctoral research fellows. 2) evaluate the "operational" efficacy of drugs that have been identified to produce QTc-interval prolongation in early clinical developme...

...ugh my poor usage of the R help system). As I am visually impaired and using assistive technology, I think I would prefer to use R from the terminal mode, i.e. by running rterm.exe found in the bin directory. I have managed to set my working directory, I know this as typing getwd() returns u:/copd/r which is the directory I want. In this directory is a file named InitialDataAnalysis.csv which I would like to read in to R. However, I am simply unable to find the surely simple command to do this. Just typing InitialDataAnalysis.csv reports "object not found" etc, as does read.file(...

Leave your ups setup as is but for under $10k (USD), have an automatic home sized standby generator installed to run the important stuff, then your power outages won't last more than startup lags, 5 or 8 seconds. Because we have central air, I bought the biggest generac, 20kw, nat gas po...

Hello everyone, I wanted to ask if there is an R-package to fit the following Poisson regression model log(\lambda_{ijk}) = \phi_{i} + \alpha_{j} + \beta_{k} i=1,\cdots,N (subjects) j=0,1 (two levels) k=0,1 (two levels) treating the \phi_{i} as nuinsance parameters. Thank you very much -- -Tony [[alternative HTML version deleted]]

...is a pretty good indication of the battery condition, and I think that could be used to trigger an "I need a new battery" email message well ahead of an unexpected total fail shutdown. I have a 20kw nat gas fired standby generator thats typically live in 5 seconds since the Mrs. has COPD, so I have never set that up here, but I believe you can find that in the Nut docs. Unless its been elided in the last 15 years. :( Cheers, Gene Heskett -- "There are four boxes to be used in defense of liberty: soap, ballot, jury, and ammo.

I'm sure there is no consistent way to reproduce this, but I'm hoping someone has some information. I have a time series we'll call y. The data gets updated every day, so I run a cron job that fits and predicts from an arima(0,0,1) X (1,1,1)_7 model. When I open R and run the script, it processes completely. If I call the script via a crontab entry R --no-save --slave <

A quick question! The number of episodes per year of otitis media follows a Possion distribution with lambda = 1.6 episodes per year. Wouldn't the probability of getting 3 or more episodes of otitis media in the first 2 years of life be: > ppois(q=3, lambda=1.6*2, lower.tail = TRUE, log.p = FALSE) [1] 0.6025197 I am confused with the lambda and 3 or more.. thx much

You report an error message: > plot(zph.revasFit[1]) Error in plot.window(xlim, ylim, log, asp, ...) : need finite 'ylim' values I have never seen this error before, and I cannot guess what causes it. You need to provide more information, and likely a small data set that produces the problem. Perhaps you have an x variable that is a constant? Terry Therneau

...se and drug related parameters. The aim of the platform is to provide a scientific basis for rational drug discovery and development with a strong focus on priority medicines. Among the various working groups, a research program has been started to evaluate biomarkers and disease progression in COPD using longitudinal models. The primary scope of this investigation is to establish which markers of disease have predictive value for the outcome of efficacy trials. Subsequently, modelling will be used to optimise clinical trial design and characterise the relevance of different clinical trial...

I have to start by figuring out where I hang it on the overhead frame thats also holding a 4000 lumen led light over an 11x54 CNC'd lathe. I am also the caretaker for my bride of 30 years who is in the later stages of COPD. So I can't leave her unattended for too long.

Greetings all; Does nut build on an r-pi4b? I have an r-pi4b running one of my cnc machines and the power bump performance due to the size of its psu and the fairly rapid start time of my standby generator, does not allow a full powerdown restart to take place, leaving the pi in a crashed state. I've purchased a factory refurbed cyberpower ups rated at 650 WA which I intend to figure
