How to reformat data from database into data.frame?
I'm trying to find a clever way to re-map data from a database query into a data.frame. Querying a database often returns a table (data.frame) like this: GeneID MethodID Value 6 1 123 6 2 456 6 3 987 7 1 234 7 3 432 8 2 190 8 3 34 8 1 864 Note that GeneID=7 doesn't have a value for MethodID=2. Note that GeneID=8 doesn't have the

Regression test failed when building on an "older" Linux cluster
We have an aging Linux Cluster here, running Red Hat 7.3. We have some business reasons for not upgrading the OS version. I don't recall the exact hardware (dual Pentium III, 4 Gbyte RAM, 1 GHz clock?), but it was pretty good in 2001 or so. We recently tried to build and install R, ver 2.6.0, for this cluster. It built and apparently ran correctly, but it failed "make check".

Confidence intervals on Lowess (eg SiZer from J.S.Marron)
Hi, I have some very noisy, relatively sparse data; a biological response of roughly ~8 subjects at ~8 times points). I've been following the data trend using a lowess line, over-plotted with several values of bandwidth, 'f <- seq(0.3, 0.9, by=0.1)'. At this point, we have no models for these data. I wonder if there is any way under R to assign some sort of confidence interval to

Problem with batch-file
Hi I have written a graphical user interface using tcltk. Now I would like to run it under rterm.exe with a batch file. I tried the following code written in a .bat file: d:\R\rw1071\bin\Rterm.exe --no-restore --no-save <d:\RGui.r> d:\RGui.out The problem is that rterm does open but the gui isn't running properly. After a few seconds rterm is closeing without doing anything more

lme() with known level-one variances
Greetings, I have a meta-analysis problem in which I have fixed effects regression coefficients (and estimated standard errors) from identical models fit to different data sets. I would like to use these results to create pooled estimated regression coefficients and estimated standard errors for these pooled coefficients. In particular, I would like to estimate the model \beta_{i} = \mu +

R and RS232-Interface?
Hi there Does any one of you know something about R and an implemented RS232-Interface? Are there any packages? Or is it possible to write an extensions or something like that in C/C++ ? The problem is that i should handle the information from a measuring device via the RS232-Interface (probably you know LabVIEW, which provides this functionality). These informations should then directly be

R ignoring quantile() in source()d file
Can anyone explain this behavior? Essentially, I've created a short file to be read in via source() that gets some descriptive information on a series of variables in a data frame. For each variable, I do three things: print('last.hc.actors') quantile(last.hc.actors,probs=seq(0,1,0.1),na.rm=T) stem(last.hc.actors) where the variable name is (in this case) last.hc.actors. All that

Debian packages for R-1.3.0
I have installed the binary packages for Debian GNU/Linux release 2.3 (woody) in the U.S. mirror of the CRAN archive. They should propagate to the main CRAN archive within a day and to the other mirrors within two days. These packages have been compiled with gcc-3.0 and g77-3.0. I believe the testing distribution currently provides only a snapshot of gcc-3.0, not the latest released version, so

Exporting R graphs (review)
Hi guys, Yesterday I posted my first couple of questions (see bottom of this message) to this forum and I would like to thank you guys for all the useful feedback I got. I just would like to make some comments: 1. Exporting R graphs as vector graphics: The best answer came from Thomas Lumley <tlumley at u.washington.edu> He suggested using the RSvgDevice package.

Matrix package: band matrix
I want to construct a symmetric band matrix in the Matrix package from a matrix where the first column contains data for the main diagonal, the second column has data for the first subdiagonal/superdiagonal and so on. Since the Matrix will be 10^5 x 10^5 or so, with perhaps 10-20 non-zero elements above the diagonal per row, I can't do it by constructing a full matrix and then using the

better way of recoding factors in data frame?
Hi all, I apologize in advance for the length of this post, but I wanted to make sure I was clear. I am trying to merge two dataframes that share a number of rows (but some are unique to each data frame). Each row represents a subject in a study. The problem is that sex is coded differently in the two, including the way missing values are represented. Here is an example of the merged dataframe:

Upgrading
Hi! As per Thomas' advice, I upgraded R by using "update.packages()" and got the following warning messages: Warning messages: 1: installation of package 'lmtest' had non-zero exit status in: install.packages(update[, "Package"], instlib, contriburl = contriburl, 2: installation of package 'quadprog' had non-zero exit status in: install.packages(update[,

collation order
The following caused a hard-to-diagnose problem for a user of the survey package. Presumably this is a strange Unicode thing, but is there a convenient reference for how the collation order is determined? I am surprised that adding the same character to the end of two strings of the same length can change the sorting order. in en_US.utf8 locale > "1//"<"10/" [1]

Package HDF5
The package works fine, but it seems not to provide access to fields, but only to the whole data in a certain file (function hdf5load(file, load = TRUE, verbosity = 0, tidy = FALSE)) Since hdf5 organizes the data and metadata in a hierarchical structure, we must explore in our problem (file>7GB), but it seems not possible with the functions in the package. Any suggestions? Please, let me know

Order-restricted inference
Hello, I looked for R packages which focused on order-restricted statistical inference, but I could find only the isoreg() function. I would need to test whether the means in my (repeated measures) data follow a given order, e.g. A<B=C<D. I took a look at the monograph by Barlow et al. (1972) on this topic and found that for my case the null hypothesis is always A=B=C=D. This might be
