Hey everyone, What am I doing wrong? I loaded the MASS package with library(MASS), and now when I type library() I get > library() Packages in library `F:\r\rw0651/library': MASS Main Library of Venables and Ripley's MASS base The R base package . . . That's fine. The problem is that when I try to use a function that I know is built

Potentially Stupid Question Department: I just tried to load a few packages in a row. First I loaded MASS, then tseries, then nls. A typical error message from the last two looked like this: Attaching Package "package:nls": The following object(s) are masked from package:MASS : profile Is this a big deal? Does it mean that I lose any functionality from the

With Tony Rossini's help we have established anonymous CVS access to a read-only copy of the main R CVS tree at cvs.r-project.org. This would be of interest primarily to those who want to track the development version (and who have access to CVS, of course). To use anonymous cvs you must log in to the server under the name "anoncvs" and with the password "anoncvs". You

Hi, I have a CSV file with various biological reactions. Subscripts, superscripts, and italics are encoded in carats, and I was wondering if R can actually recognize those and print actual superscripts, etc. Here's an example: <i>S</i>-adenosyl-L-methionine + rRNA = <i>S</i>-adenosyl-L-homocysteine + rRNA containing

Hello, I recall reading a thread months ago on this mailing list about handling very datasets under R, but I can't seem to find it. This has become particularly important recently, because I've been playing with a dataset containing information about every fatal car accident in the U.S. since 1975; in total, the relevant files are about 120 megs. I'd like to load all of these into R

Hey everyone, Might it be possible for future versions of PC-R to highlight the opening brace in a pair, a la emacs? Programs that do that are infinitely friendlier than those that don't.

I have sort of an emergency question for the list. One of my professors for an S-Plus intensive class distributed a function to produce partial regression plots. I need to run it under R, because I'm doing the homework on my home computer with a modem; hence I don't have the speed required to emulate X-Windows and run S Plus off one of the campus servers. Bottom line: I'm using R.

Hi I am using mathematical anotation to make the labels in a barplot in italics. as an example (adapted from http://finzi.psych.upenn.edu/R/Rhelp02a/archive/129808.html): tt <- c("italic(First~~set)", "italic(Second~~set)", "italic(third~~set") barplot(1:3, names.arg=parse(text=tt)) But I would like to have it with "set" in a second column, like tt

Hi there, I'm using R1.0.1 Windows 98. This file contains some inputs and an aov function code. Can someone check it for me? Somehow I got completely different answer when typing them in R and in Splus. Splus gives me this: > summary( Turnip.aov ) Error: Blocks Df Sum of Sq Mean Sq F Value Pr(F) Residuals 3 163.7367 54.57891 Error: Plots %in% Blocks

I am trying to get superscripts on the y-axis. I keeping getting syntax error: This works as advertised: > plot(c(1:10), ylab= expression(paste(x^ theta))) This does not: >plot(c(1:10), ylab= expression(paste(x^ {++}))) Note that I am trying to get ++ as superscript.

Does anyone know of any comprehensive literature (like a book, collection of articles, etc.) that walk thorugh example of ARIMA modeling with the ts package of R? Genarlly if you've just started to learn the R-language and are all week long with ARIMA, what is a fast-pace source that you would recommend (to a beginner) ? Thank you, Krasi

Is there some way to remove superscripts from objects returned by html/xmlParse (XML package)? h <- "<html><p>Cat^a</p><p>Dog</p></html>" doc <- htmlParse(h) xpathSApply(doc, "//p", xmlValue) [1] "Cata" "Dog" I could probably remove the <sup> tags from the "h" object above,

Hi, Although I understand how to use expression and paste to add superscripts and symbols to my graphs, I have a problem with adding superscripts to an existing string. For example, I read in the following from a separate file: 25Mg(p,g) I want to convert that to superscripts etc. (in LaTex format): $^{25}$Mg(p,$\gamma$) This needs to then be put into a graph title. Any ideas? I know that I

Hi, I am reading in a CSV file of chemical reactions where the subscripts and superscripts are encoded in angle brackets, like below: 2 H<SUP>+</SUP> + 2 O<SUB>2</SUB><SUP>-</SUP> Is there a way to convert these to actual sub/superscripts and save them in another excel file? I greatly appreciate the help! Thanks, -Nina PS. I asked this before, but I

I'm trying to read some web tables directly into R. These are both genome sequencing projects (eukaryotes and metagenomes) from NCBI and look very similar; however, only the first one works. http://www.ncbi.nlm.nih.gov/genomes/leuks.cgi http://www.ncbi.nlm.nih.gov/genomes/lenvs.cgi I added ?dump=selected to the end of the url string to get a tab- delimited file (which is what happens

Sorry to ask this but does anyone knows a good text that helps with the basic programming side of R. I understand the statistics behind most of R but i have real difficulty with the data types and how R views them. As a part of that could you help me with another problem. I know how to read data in from a file in terms of read.table but how do i single a column out or even just download a

Following on from my previous mail! plot(1:10,1:10) mtext("title", side=3, adj=0, font=3, cex=1.5) This works as expected and puts the font in italics. tag <- "A)" suffix <- "genea::" plot(1:10,1:10) mtext(bquote(.(tag) ~ Delta * .(suffix)), side=3, adj=0, font=3, cex=1.5) Here, the font isn't in italics, it's normal.
