plot portion of a line
Dear HelpeRs, Given: x <- rnorm(50) y <- rnorm(50) plot(x,y) abline(lm(x ~ y)) Is there a way to plot just a portion of the line? Say for values of x > 2.0 or x > -2.0 and x < 4.0. (Still fitting all the points.) Thank you, jab -- John Bollinger, CFA, CMT www.BollingerBands.com If you advance far enough, you arrive at the beginning.

stacked plots
Dear helpeRs, Is there a better method of producing stacked charts than par(mfrow(3,1)), plot(x), plot(y), plot(z)? What I would like to do is produce a chart of several panes stacked vertically with no space between them so they appeared to be a single figure. I've attached a small example, though it is not clear that it will make it, as the posting guide doesn't say which sort of images

R 2.3.1 I wrote a little script to do some cross correlations.

.Rprofile under Windoze.
I am (for my sins) having to do some work using R under Windoze. I wanted to set up a .Rprofile to control my set-up. The docs on .Rprofile say that it can/should be placed in ``the user's home directory''. ``An Introduction to R'' observes lucidly that this concept needs to be clarified under Windoze. Following the suggestions in An Introduction to R, I tried putting a

Block comments in R?
Hello list, Is there any way to perform a block comment in R? In C++, anything in between a /* and */ is considered a comment, and it allows programmers to comment out chunks of code for testing and debugging. Is there such a feature in R? Cheers, Wee-Jin

Command area in SciViews 0.8.9 - second try
Dear all I am writing again with a question I posted a few weeks ago (to no avail). I have a problem with SciViews for R.

Install R in Linux
Hi, Is it possible to install R in a linux box (Debian) without being a root. I know I can compile the R source code, but there is no F77 compiler on the box. So is it possible to install binary R without being a root? Send instant messages to your online friends http://uk.messenger.yahoo.com [[alternative HTML version deleted]]

currency or stock trading strategy
Hi, are there any good charting and analysis tools for use with currencies, stocks, etc. in R? I have some tools to download currency data from the NYFRB using python and XML. Can we get and parse an XML download using R? Can we have interaction in R plots? Does anyone use R for back-testing trading strategies? Are there any forums for discussion of using R for this specific purpose (apart

cluster in R
hi, is there some good summary on clustering methods in R? It seems there are many packages involving it. And I have two questions on clustering here: 1. Is there a way of evaluate the effecitives (or seperation) of clustering (rather than by visualization)? 2. Is there a search method (like genetic search) which can help find the best subset of attributes which gives best seperation? Thanks,

Connecting to a SQLBASE database with R
Hi, I am trying to extract data from a database with R in order to produce monthly statistics. I found in the R Website, the package RODBC, RSQLite and others ones which permit this kind of extraction. The database I want to be connected with is a SQLBASE 7.0 database. So, I would like to know if, using one of these package or another one, I could be able to connect with this type of database.

Book recommendation for newbie to stats and R?
I'm trying to learn statistics and R at the same time. I have an undergraduate science degree and one year of calculus (30 years ago), but never took a stats course. I hope to take some stats courses in the next year, but thought I would start to see how much I could teach myself. I work for an organization that analyses behavior change communication programs regarding HIV/AIDS and

Does SQL group by have a heavy duty equivalent in R
I have hundreds of humans who have undergone SNP genotyping at hundreds of loci. Some have even undergone the procedure twice or thrice (kind of an internal control). So obviously I need to find those replications, and confirm that the results are the same. If there is discordance then I need to address it. I tried to use the aggregate function nr.attempts

OT: any recommendation for scripting language
Right now, I am using SAS and S+/R. As a new year resolution, I am planning to learn a scripting language. from statisticians' point of view, which scripting language is worth to learn, perl, python, or any other recommendation? (Most likely, I will be learning it in windows.) Since I am not in research, I will prefer one widely used in industry and related to statistical work. if you

I never did solve my "puzzle" as to how to kill a Linux process that seems to be deadlocked in kernel space, but thought I would report to the list that the server did manage to stay up and continue to process several thousand calls per day: ast% uptime 11:49:37 up 1000 days, 16:30, 1 user, load average: 1.00, 1.00, 1.00 ast% Since for the past four weeks I have forced my poor

split a character variable into several character variable by a character
Dear Mao Jianfeng, "r-help-owner" is not the place for help, but: r-help at r-project.org (CC-ed here) In any case, strsplit() does the job, i.e.: > unlist(strsplit("BCPy01-01", "-")) [1] "BCPy01" "01" You can work with the whole variable, like: splitpop <- strsplit(df1$popcode, "-") then access the first part with >
