using Paraview "in-situ" with R?
...zzled. Paraview is a competetive sibling of VisIt, so I don?t know if they would be interested. The packages we developed are viable for that purpose. There is a lot in R that could benefit Paraview (or VisIt).

Text Summarization
Is there a text mining/ NLP package in R that could do text summarization? For example, take a huge text as input and provide a summary of the text. In package tm, summarization is defined more as high frequency terms which is not what I want. I actually want a summary of what is present in the huge volume of text. Any help on a R package would be helpful. Thank you. Ravi -- View this message

tyring to save plots using windoze 7 and cygwin
...t_rate.pdf",type="pdf") q() Now apparently R does save the plot in a default file Rplots.pdf which is just fine for my immediate needs but this may have limitations for future usages. Just curious to know what other may have gotten to work or not work. Thanks. - - - - - - Mike Marchywka | V.P.

R packages to send plottable data to external apps

using Paraview "in-situ" with R?
I had previously asked about R interfaces to various "other" visualization tools specifically lightweights for monitoring progress of various codes. I was working on this, https://github.com/mmarchywka/mjmdatascope but in the meantime found out that Paraview has an "in-situ" capability for similar objectives. https://discourse.paraview.org/t/does-or-can-paraview-support-streaming-input/13637/9 While R does have a lot of plotting features, it seems like an excellent tool to interfac...

getting R-readable data , not pictures, from US OTS "data" pages

Generating uniformly distributed correlated data.
I wish to generate a vector of uniformly distributed data with a defined correlation to another vector The only function I have been able to find doing something similar is corgen from the library ecodist. The following code generates data with the desired correlation to the vector x but the resulting vector y is normal and not uniform distributed library(ecodist) x <- runif(10^5) y

How long does skipping in read.table take
I know I could figure it out empirically - but maybe based on your experience you can tell me if it's doable in a reasonable amount of time: I have a table (in .txt) with a 17,000,000 rows (and 30 columns). I can't read it all in (there are many strings). So I thought I could read it in in parts (e.g., 1 milllion) using nrows= and skip. I was able to read in the first 1,000,000 rows no

R-3.0.1 - "transient" make check failure in splines-EX.r
Hello. I seem to be having the same problem that Paul had in the thread titled "[Rd] R 2.15.2 make check failure on 32-bit --with-blas="-lgoto2"" from October of last year <https://stat.ethz.ch/pipermail/r-devel/2012-October/065103.html> Unfortunately, that thread ended without an answer to his last question.

Spatial cluster analysis of continous outcome variable
Dear R Users, R Core Team, I have a two dimensional space where I measure a numerical value in two situations at different points. I have measured the change and I would like to test if there are areas in this 2D-space where there is a different amount of change (no change, increase, decrease). I don´t know if it´s better to analyse the data just with the coordinates or if its better to group them

Using t tests
Dear Sir, I am doing some work on a population of patients. About half of them are admitted into hospital with albumin levels less than 33. The other half have albumin levels greater than 33, so I stratify them into 2 groups, x and y respectively. I suspect that the average length of stay in hospital for the group of patients (x) with albumin levels less than 33 is greater than those

problem loading rgdal with Rapache, problem solved due to libexpat with apache.
Has anyone had problems with Rapache that don't show up on command line execution of R? I just ran into this loading rgdal in Rapache page and having a problem with loading shared object. The final complaint was that Stop_XMLParser was undefined- this was surprising since grep -l showed it in expat lib and it worked fine from command line. Finally, I noted the search path had apache/lib ahead

so current status of interactive PDF creation isl? trying to explore econometriic convergence thread
I think I just saw a thread go by on " how do I make interactive PDF from rgl output" but I ignored it at the time and can't seem to find consensus result on google. Essentially I wanted to create pdf or other output to share a 3D plot and let viewers interact with it but it still wasn't clear on easiest way to do this. Is this 2009 page the best reference?

Identify period length of time series automatically?
-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 Hi I have 10.000 simulations for a sensitivity analysis. I have done a few sensitivity analysis for different response variables already, but now, as most of the simulations (if not all) show some cyclic behaviour, see how the independent input parameter influence the frequency of the cyclic changes and "how cyclic" they actually are.

re-arranging data to create an image (or heatmap)
Let me start by introducing myself as a biologist with only a little knowledge about programming in matlab and R. In the past I have succesfully created my figures in matlab using the hist3d command, but I have not access to matlab right now and would like to switch to R. I have used the plot command to create a figure of my data and it does almost what I want it to do. My data matrix looks like

A question on glmnet analysis
Hi, I am trying to do logistic regression for data of 104 patients, which have one outcome (yes or no) and 15 variables (9 categorical factors [yes or no] and 6 continuous variables). Number of yes outcome is 25. Twenty-five events and 15 variables mean events per variable is much less than 10. Therefore, I tried to analyze the data with penalized regression method. I would like please some of the
