Saludos colegas. Estoy intentando cargar un archivo arff con el paquete RWeka pero me lanza el error FileNotFoundException cuando intento ejecutar la instrucción en R. Este es el código: datos<- read.arff(system.file("arff","cereals.arff", package = "RWeka")) El archivo cereals.arff y el script con el código R están en el mismo directorio, sin embargo, no me

Hello Asterisk Users and those with an Interest in VoIP Tech, The agenda is open for our next meeting. I think we'll plan on an open discussion of anyone's choosing. If we're lacking a topic, we'll give a demo of installing fail2ban for your asterisk system. Bring your questions, ideas and projects and we will help you work through them. Jimmy John's is just a block away

Hi Jonathan, After reading/skimming through the official LLVM backend documents, I actually tried following your steps to write a new backend, but how to write td files still remains unclear. The details are not well explained, though I know most of them can be found in other documents or have already been documented somewhere in the LLVM source code or td files. For a beginner with no

Dear R-helpers, I'm stuck with a little problem that surely has an easy solution but I can't think of a way to solve it. I'd really appreciate any help you can offer me! I'll provide a small example. Given a dataframe data.txt that looks like this: ID freq Var Var_mean Ratio_mean Var_median Ratio_median Var_sum Ratio_min Var_max Ratio_max Var_min

Dear all,I am a new user of WinBUGS and need your help. After running the following code, I got parameters of beta0 through beta4 (stats, density), but I don't know how to get the prediction of the last value of h, the variable I set to NA and want to model it using the following code.Does anyone can given me a hint? Any advice would be greatly appreciated.Best

Hi - The problem is with two abline(s). Attached are: 1) jnk.r to run program 2) jnk.rin the data 3) jnkps.eps the postscript output 4) jnkscreen.bmp (from photoshop after bmp copy to clipboard) in jnk.zip the eps and bmp are different on my machine (windows 2000) any suggestions appreciated bob >>> Diego.Kuonen at epfl.ch 03/18/00 08:24AM >>> "Robert L.

Hi, Sometimes it's desirable to bind a port forward to port 0: especially when scripting port forwarding, and more especially so with the '-f -N' options. The version of OpenSSH bundled with OSX (4.7p1) accepts '-L 0:192.168.1.1:22', but only if ran as root (I guess this was more an accident than a feature). I saw that the current version (5.1p1) will decline such an options,

Dear R Can you tell me how to change the working directory of R It's just that I have some text files that I wish to save separately from the R filing structure eg. into C:/my documents and need to change the working directory of R so that it reads these files . This means if I ever upgrade the current version of R nothing will be effected. brett Brett Stansfield Environmental Scientist -

Dear R help I have been trying to conduct a chi square test on two groups of variables to test whether there is any relationship between the two sets of variables chisq.test(oxygen, train) Pearson's Chi-squared test data: oxygen X-squared = 26.6576, df = 128, p-value = 1 > chisq.test(oxygen) Pearson's Chi-squared test data: oxygen X-squared = 26.6576, df = 128,

Hi, I have a vector of strings (class character) with 6 elements (length 6). I call it 'names'. "Graham Chapman" "John Cleese" "Terry Gilliam" "Eric Idle" "Terry Jones" "Michael Palin" And I want to turn it into another vector of strings called 'shortnames' with the same length. The new vector should look like:

Dear R, I recently did a canonical correlation analysis on two subsets of data (location and weather). So I now have canonical scores for location and weather. but I'd now like to do a scatterplot matrix using the pairs statement. Is there a way to somehow join location.U and weather.V to become a new data set from which I could undertake a scatterplot matrix of the canonical variates?

Dear R I recently performed a cluster analysis. It produced the dendogram no problem but unfortunately the font size of the row.names were all cluttered due to their large size So I tried to change the font size using plclust(cluster.results, labels=iris$specie, cex=0.8) and R came back to me saying Error in plclust(cluster.results, labels = iris$specie, cex = 0.8) : unused argument(s)

Ok. I`m trying to run a Poisson glmm with an observation-level random intercept. But I`m getting the following error for the 'Baci' variable: 'Error: (maxstephalfit) PIRLS step-halvings failed to reduce deviance in pwrssUpdate'. I guess this message is because the baci variable is not a an integer, and cannot be transformed into an integer as R has a threshold of 2x10^9 even in

Hi, I'm estimating a loglogistic aft (accelerated failure time) model, just a simple plain vanilla one (without time dependent covariates), I'm comparing the results that I obtain between aftreg (eha package) and survreg(surv package). If I don't use any covariate the results are identical , if I add covariates all the coefficients are the same until a precision of 10^4 or 10^-5 except

can you recommend a good manual for R that starts with a data set and gives demonstrations on what can be done using R? I downloadedR Langauage definition and An introduction to R but haven't found them overly useful. I'd really like to be able to follow some tutorials using a dataset or many datasets. The datasets I have available on R are Data sets in package 'datasets':

Dear R Is there a way to apply row names as labels to a scatter plot matrix , I tried pairs(dogs, labels=row.names) Error in strwidth(labels, "user") : cannot coerce type closure to character vector I'm not sure what this means, however maybe you might know of a way to do this? brett stansfield
