I'm teaching a class and using R for the first time. We're talking about the bootstrap, and I've been trying to get R to replicate some simple bootstrap programs with no success. I'd like to be able to use the boot.ci function to produce confidence intervals (non-parametric) for some simple statistics, and this requires first creating a "boot" object. The boot

hi there, anybody knows how to import data into R from splus directly? I have a huge amount of data in splus format, which will cost forever for me to transform the data back to ascii or something else and then read them into R. thanks a lot. ximing -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-help mailing list -- Read

Hi R folks, I'd like to announce several new R users groups here in SF, LA, NYC, and Ottawa - as well as their next scheduled event. The goal of these user groups, besides gently explaining 'drop=TRUE' to the uninitiated, is to exchange knowledge, promote best practices, and spur the adoption of R for innovative applications. If I've missed any groups here, please feel to add on

Dear Sir, I am using R for the first time and I am looking for a function or a command that allows to import Splus data into R. I have already heard about functions called "readSdata" and readSfiles" in the "Rstreams" package. I did not find the last new version of this package on the CRAN and its old one did not work on R 1.8.0 (the vesrion that I am using). Would you

if R had something like > python -c "print(sum([1,2,3]));print(3*2)" 6 6 but I guess the only way to do this is by writing the string to a tmp file and then doing something like "R CMD BATCH --quiet" on the tmp file I would like to use this for an R service, which allows you to select any string in any application and replace it by its R evaluation === Jan de Leeuw;

Dear R-users, I successfully installed the package Rstreams under linux, but my first attempt to do so on SGI IRIX 6.5 (64bits) lead to the following error message. -------------------- laurent at genome> R CMD INSTALL Rstreams Installing source package `Rstreams' ... creating cache ./config.cache checking for ftruncate... yes checking size of long double... 16 updating cache

Hi all. I'm trying to install the packages Rstreams and RPgSQL, but with no success. I did R INSTALL name package but if I try library(Rstreams) I get the following error: Error in library.dynam("Rstreams",pkg,lib): dynamic library 'Rstreams' not found Error in library(Rstreams): .First.lib failed Where did I go wrong? I'm using R 1-1-1 on a Debian GNU/Linux box.

Hello, I'm looking for a working compiled library of "rstreams" for mac OS 9 and for mac OS X. I could find one (somewhere) but it is not loading. It says in R 151 under OS 9.2: Error in dyn.load(x, as.logical(local), as.logical(now)) : unable to load shared library "PRO-096-system:Applications:Languages:rm151:library:rstreams:libs:RstreamsL ib": error code -2807

Hi all, in the last time I've intensively used Rstreams to read and write from binary files. Now I'm wondering if it is possible to use Rsteams functions with gzipped files. But I haven't found the trick: > p1c.gzip <- gzfile("daten/p1c_all.mea.gz", open="rb") > readBin(p1c.gzip, integer(), n=64,size=2) [1] 84 1 400 1 749 0 0 0

I have used S-Plus for Windows for some time and have a large collection of personal programs. I have recently installed R-1.1.1 under Linux. I can read the .ssc files from S-Plus into emacs and save to R, but this is apt to be tedious. Any shortcuts to recommend? Will linux R read the _Data files from Windows S-Plus? Would Windows R serve as a useful intermediate transfer? -------------- next

Dear R helpers, is there a function or way within R to solve A'A=S for A, where all matrices have p x p order and S is a variance-covariance matrix? Thank you, Ralf Engelhorn

It is not clear to me that one can. If the singular value decomposition of A is the triple product P d Q', then the singular value decomposition of A'A=S is Q d^2 Q'. The information about the orthonormal matrix P is lost, is it not? ********************************************************** Cliff Lunneborg, Professor Emeritus, Statistics & Psychology, University of Washington,

Hi, I have a CSV file that is formatted well, except that the last line is a "summary" not is CSV format. Toy example: label_1, label_2, label_3 1,2,3 3,2,4 2,3,4 Total Rows: 3 When I try to import this into R with: d <- read.table("foo.csv", header=T, sep=",") It fails to import properly because of the last line. Currently, I have a shell script that strips

If I have two models that are in a one-to-one relationship in Ruby on Rails, and I wish to delete a record. How do I make sure I will delete all the related data from both tables? Is there a simple elegant Ruby way to do this?

I would like to produce a bar plot with varying-width bars. Here is an example to illustrate: ww <- c(417,153,0.0216,0.0065,556,256,0.0162,0.0117, + 726,379,0.0358,0.0501,786,502,0.0496,0.0837, + 892,591,0.0785,0.0795) yy<-t(t(array(ww,c(2,10)))) barplot(yy[,2*1:5],las=1,space=c(.1,.5),beside=T) produces a barplot of 5 pairs of bars that are of equal width

Hi, I'm having difficulty coming up with a good way to subest some data to generate statistics. My data frame has multiple observations by group. Here is an overly-simplified toy example of the data ========================== code v1 v2 G1 1.2 2.3 G1 0 2.4 G1 1.4 3.4 G2 2.9 2.3 G2 4.3 4.4 etc.. ========================= I want to normalize the data *by group* for certain variable.

Hi, I have several data structures (xts structures). I then have a list of the names of those objects. I'd like to access the object by name. For example: foo1 <- as.xts(....) foo2 <- as.xts(...) foo3 <- as.xts(...) structs <- c("foo1", "foo2", "foo3") for (thisOne in structs){ print(thisOne$colA) } The above fails. Clearly I'm missing a
