Hi R-users, My question is more methodological one, rather than technical. I have to samples representing residuals based on two measurements techniques (resid1,resid2; n=69). I need to compare two samples, to reject one technique (the worse one), and to keep the one which gave lower residuals (better one). What to look for? What should I analyse? Means, variance, std. deviations? Based on

Hi R-users, How can I found the number of a distinct values in a data frame (occurrence of distinct values)? The dataframe consists of several thousands integer numbers.

Hello R-users, Is there any more sophisticated way how to identify the dataset outliers other then seeing them in boxplot? I wanna exclude them from further analysis and I am interested in their position in my vector data. Rado -- Radoslav Bonk M.S.

Hi R-users, I am using "postscript("xx.eps", horizontal=FALSE, onefile=FALSE, height=6, width=10, pointsize=10)" and "barplot(xx.dat)" in R to produce EPS graphics for LATeX document. When checking the graphics with "gv" I see that it was not produced with full details. The main graphic is there, but axes labels and titles are missing. While checking the

Hi R-users, I have a set of elevation residuals as geodata points. I would like to display them in the following way: -negative values using pch=20 (filled circle) -positive values using pch=1 (empty circle) while using the cex.max=5, cex.min=0.1 for points() to represent the residuals value. Basically I would like to distinguish neagtive and positive values at my map. How to do this. Thanks

Hi, Does anybody know suitable documents (manuals) on writing user functions (covering loops, conditions ...) in R? Other than the usually available manuals. Thanks, Rado -- Radoslav Bonk M.S.

Dear R users, I have to include typical UNIX formated R commands and outputs into the article using LaTeX. What is the easiest way to include R prompt commands and text outputs (including messages) into LaTeX documents? Is there any template or library? So far I'm trying to produce R commands in LaTeX using LaTeX general format options. Thanks, Rado

Dear R-users, I was able to make ROracle package to connect to the DB (Oracle91, 64bit, on Solaris). But after executing siple SQL query, "fetch" commaned gives me an empty dataframe. ### RORACLE INSTALATION PROCEDURE ### R CMD INSTALL --configure-args='--enable-extralibs' --enable-oracle32=no ~/tmp/ROracle_0.5-5.tar.gz #since we have 64bit Oracle9i instalation PROBLEM:

Dear R users, I'm coming back to R after while. I have a data frame with 200 columns, each column has a name. How to extract all columns to a new dataset, but the specified (by names) ones? I was playing with that for a little bit using the vector syntax but got several syntax errors. Thanks, Rado

Dear R-users, I have two outliers related questions. I. I have a vector consisting of 69 values. mean = 0.00086 SD = 0.02152 The shape of EDA graphics (boxplots, density plots) is heavily distorted due to outliers. How to define the interval for outliers exception? Is <2SD - mean + 2SD> interval a correct approach? Or should I define 95% (or 99%) limit of agreement for data interval,

Dear R users, I'm working on implementation of hydrometeorological DB in Oracle9i and would like to use R, as a plotting engine for graphs and maps and also to perform some non trivial statistics on DB data using R. Thus any links with examples or efforts on: - general DB and R cooperation - Oracle91 and R cooperation - Oracle PL/SQL and R are welcomed. Thanks in advance, Rado --

Hello, I am the author of the Bonk audio compression program... i've just been looking at your comparrison table, and i noticed bonk gets marginally better compression than Flac on some files (actually i was rather surprised to see bonk on the list at all, it's not exactly high profile :-) ). Bonk in lossless mode is a pretty naive implementation of a predictive coder, so the main

oh boy, looks like I screwed things up some trying to add hosting for another domain besides my own I thought I went by the book here but something sure ain't right. my real email address is rado at rivers-bend.com then a few days ago, I tweaked sendmail.mc I think it was to masquerade ideallightinginc.com (the other domain) now I just noticed I am showing as rado at ideallighting.com

Hi, I am just migrating to Centos from fedora core 3. I have 3 boxes involved here: Box A --Fedora 3 (doing the dns, http, sendmail serving duties) Box B --CentOS Box C --CentOS I used to run root passwordless ssh both ways from boxes A and B mainly set up to keep the 2 boxes in sync w/rsync ... these 2 boxes normally ran one being the slave and the other being the master...the master did all

Hi developers! I would like to know if it is possible to use Vorbis encoder as a real-time encoder for Pocket PCs, because they don't have floating point based unit. If not, do you plan to make a fixed-point based encoder? I'm very interested in this issue so if I could help, I will. I'm working on fixed-point MP3 encoder for XScale devices in cooperation with Intel. It seems that

Hi! I would like to hear what printers go good w/our operating system. While back, I should have checked w/y'all like I'm doing now but I just went ahead and bought a Konica-Minolta PagePro 1350W. Now that W at the end of 1350 is a huge word that means WINDOWS! grrrr! It's a great printer 21pgs/min etc but it doesn't like linux at all and their tech spt will tell you as much. I

Hello, Dovecot 2.3.4_3 on FreeBSD 11.2. I am using mdbox Alternate Storage since about two years without any problems. However, the disk containing this storage is almost full and I have to move this data to another disk, probably zpool. Would it be okay to do the following? 1) Shut down dovecot (and mail server) so no new mail comes in. 2) Copy/move all files in ALT location to new disk,
