Dear all, I have a very large dataset (1712351 , 20) and would like to plot only the arrows that represent the contribution of each variables. On the sample below I woild like to plot only the explanatory variables (Murder, Assault..) and not the sites. prcomp(USArrests) # inappropriate prcomp(USArrests, scale = TRUE) prcomp(~ Murder + Assault + Rape, data = USArrests, scale = TRUE)

Dear R users, When I tried to use princomp() from stats packages to do Principal Components Analysis, I am not very clear what is the "scale". And the scores are different from "PROC PRINCOMP" procedure from SAS. Using the example data from this package: restpc <- princomp(USArrests, cor = TRUE) > restpc$scale Murder Assault UrbanPop Rape 4.311735 82.500075

I'd like to search for a particular string in an SQLite database using RSQLite, but I'm running into problems constructing the query properly, because of embedded quotes and parens in the string. Is there a function that escapes these for me, or some other fixup that would let me do the queries below? In the real situation I don't have control over what strings get searched for.

Hi, I am running the RODBC examples form the help guide. I am trying to UPDATE a table in an Access data base but I am having an error. library(RODBC) library(termstrc) path = getwd() setwd(getwd()) dbName = "data.mdb" pathdbname = paste(path,"/",dbName,sep="") accesChannel = odbcConnectAccess(pathdbname, uid = "", pwd = "")

Hi guys, I am new to R, so sorry if my problem seems trivial. Sometimes I encounter some lists, which I cannot index their components with [ . ] For instance the prcomp() function returns a 'prcomp' object whose components are some 'lists'. the second component is a list that comtains the following: > mylist <- churn[2] > class(mylist) [1] "list" >

I have tried to find a neat way to include graphs from R in LaTeX documents, but have not succeeded (I work with a WinEdt/MikTeX combination). The two roads I have stumbled along so far are the following: *Generate postscript files and convert them into EPS files by means of GhostScript or other not so straightforward tools. *Generate pictex files and include these. None of these solutions have

bRotheRs & sisteRs, I am once again attempting to learn enough Latex voodoo to get something done, and failing comically. The document "RJAuthorguide.pdf" mentions that one can get page width figures through the use of the "figure*" or "table* environments, but despite considerable searching through the mail archives and reading Frank Harrell's discussion of

Dear list, Being new to both the postgres database, ODBC and the RODBC interface, I am somewhat confused by some of the problems I am experiencing trying to connect R to the database. Whai I am trying is basically the example part of the help file for the sqlSave function: > library(RODBC) > odbcConnect("theodor") -> channel > data(USArrests) > sqlSave(channel,

Hi, I run the example for princomp for R211 I got the following error for biplot > ## The variances of the variables in the > ## USArrests data vary by orders of magnitude, so scaling is appropriate > (pc.cr <http://pc.cr> <- princomp(USArrests)) # inappropriate Erreur dans cov.wt(z) : 'x' must contain finite values only > princomp(USArrests, cor = TRUE) # =^=

I've generated a version of the classic dotplot of the barley data with library(lattice) data(barley) trellis.device("postscript", color=TRUE, file="barley2x3.ps") old.settings <- trellis.par.get() trellis.par.set("background", list(col = "white")) lset(list(superpose.symbol=list(pch=c(19, 1, 25, 2, 15, 22, 23),

Dear All, when I'm running a PCA with prcomp(USArrests, scale = TRUE) I get the right principal components, but with the wrong sign infront Rotation: PC1 PC2 PC3 PC4 Murder 0.5358995 -0.4181809 0.3412327 0.64922780 Assault 0.5831836 -0.1879856 0.2681484 -0.74340748 UrbanPop 0.2781909 0.8728062 0.3780158 0.13387773 Rape 0.5434321 0.1673186 -0.8177779 0.08902432 instead of PC1 PC2 PC3 PC4

So as often there is more to it than you first think.

Hi there: Using \setkeys{Gin}{width=1.0\textwidth} \setkeys{Gin}{height=10cm} \setkeys{Gin}{height=0.8\textwidth} all seem to work under R-2.1.1 under sparc, solaris2.9, but \setkeys{Gin}{scale=0.3} \setkeys{Gin}{angle=90} do not work. I have not been able to find relevant information, googling on setkeys proved confusing, at best. http://cnlart.web.cern.ch/cnlart/218/node85.html states:

I am developing an R package which includes datasets. The build and install works correctly.

Hi, i found tis message in the archive and have got the same problems ? John, perhaps you have found now a way install RPgSQL for windows2000, or anybody other ? many thanks for advance christian [SNIP] I wonder whether anyone has succeeded in building either the RPgSQL or the Rdbi.PGSQL and Rdbi packages for Windows. If so, would you be willing to share either the binary package(s) or

Earlier today I posted a problem importing an R graph into a LaTeX file of seminar class: specifically, the graphic was showing up rotated 180 degrees, along with the rest of the page it was on. In a real victory for open-source software, I got lots of responses with three distinct approaches, each of which appears to solve the problem. Try getting fast, correct help from Microsoft on a Sunday

Dear R-developers, I finally got around to install R 1.1.0 but had problems at the `make check' stage. After compiling the released R 1.1.0 version the `make check' stage stopped while checking the examples in base. There was some problem with the quantile function and the check stopped complaining that NA's are not allowed. But I assume that this problem is already known because

Hello. I'm writing some simple text using sweave, and faced a strange problem with eps files produced for my plots (one example attached). Individual eps files are interpreted by ghostscript just fine, and show up without errors. But once I try to include them into main LaTeX/Sweave document (using regular \includegraphics, produced by Sweave), ghostscript gives me this error on those files:
