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.

R 2.3.1 I wrote a little script to do some cross correlations. The symbols are in a text file like so: symbols.txt ibm dd csco """ require(tseries) symbols <- scan("symbols.txt", what = 'character') for(line in 1:(length(symbols)-1)) { assign(symbols[line], get.hist.quote(instrument = symbols[line], start = "2005-09-01", quote =

Hello, For numbers in the range 100 to 100,000,000 I'd like to decimal align a right-justified comma-delineated column of numbers, but I haven't been able to work out the proper format statement. format(num, justify=right, width=15, big.mark=",") gets me close, but numbers larger than 1,000,000 project a digit beyond the right edge of the column, which I really don't

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

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,

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. It's probably a slightly stupid question but I cannot find a solution to a very elementary problem. I am using SciViews 0.8.9 on with R 2.3.1pat on a Windows XP Home machine. R is set to SDI mode, I start R, enter "library(svGUI)", SciViews starts properly, I can

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.

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

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.

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

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

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 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

After searching multiple combinations of keywords over the past two days and downloading n R graphics tutorials, I have not been able to find anything online or in my R books about how to save multiple plot panes to PNG. Specifically, I am using the irf() function in the vars package to generate plots of Impulse Response Functions: > x.data <-

Hi, I'm currently using barplot to generate vertically stacked bar charts. I'd like to be able to use the "asp=1" parameter with barplot(), but doing this causes the y axis to be placed on the far left as shown in the attachment demo.pdf. I could get around this by using the negative values for the line parameter of the axis() function. I'd rather not do this and imagine

Dear all, I would like to create a vertically stacked area chart in R. The data are presented in the attached text file. I would like to see the trend in values for the different groups with sediment depth (that's why I would like to create a vertically stacked chart; normally sed_depth should be = x, but I want it plotted on the y-axis). In the packages available to create stacked area
