Standard introductory presentation
...resent R and doesn't talk gibberish, The closest I found was by Tyler K. Perrachione from MIT, which I think I might use if push comes to shove, but I wanted to ask whether anyone of you knows of a "official version" by one of the Core Project members ?

R table as integrable object for large Latex Documents - avoiding SWeave
...itions, requiring a lot of time to get right and ultimately also providing much of a source for errors. Thus my question is whether you know of any alternative how to create pictures or CSV style objects that *easily* integrate into LaTeX, keep their format etc. Thanks Christian ----- Christian Langkamp christian.langkamp-at-gmxpro.de -- View this message in context: http://r.789695.n4.nabble.com/R-table-as-integrable-object-for-large-Latex-Documents-avoiding-SWeave-tp4640183.html Sent from the R help mailing list archive at Nabble.com.

Subtract matrices within arrays along indices
I have the following array: 3 dimensional object, one dimension being year. Object is 3*3*3 library(plyr, reshape) a1<-rep(c(2007,2008,2009),9) a2<-c(rep("a",9),rep("b",9),rep("c",9)) a3<-c(rep(c(rep(1,3),rep(2,3),rep(3,3)),3)) a4 <- rnorm(27) A<-data.frame(cbind(comp=a2,val=a3, year=a1, a4)) A1<-melt(A, id=c("year", "comp",

LaTeX consistent publication graphics from R and Comparison of GLE and R
...raphing throughout the thesis (i.e. same colour coding etc.). Does anybody have any experience with GLE, ideally working with it with CSV tables generated within R ? Or does there exist another way to generate 'visually LaTeX consistent' graphics within R ? Any takers ? ----- Christian Langkamp christian.langkamp-at-gmxpro.de -- View this message in context: http://r.789695.n4.nabble.com/LaTeX-consistent-publication-graphics-from-R-and-Comparison-of-GLE-and-R-tp4645218.html Sent from the R help mailing list archive at Nabble.com.

Re place Values within vector using Translation vector
Dear everyone I would like to change values in vectors doing a translation. i.e. I have a start vector giving me the levels in one vector (numbers 1 to x - rating) and then I have a second vector giving me the values to be allocated (loss probabilities), but the number of potential rating classes and loss estimates is still subject to a lot of discussion. Attached a simplified version of the

Adjusting the Axis in a histogram to the prespecified breaks
Hello I tried a few searches on hist, histogram, equidist and space (space=0 was mentioned in one contribution), but none of that so far worked. It also says in the help "##-- For non-equidistant breaks, counts should NOT be graphed unscaled:" - which is precisely what I am looking for, but I cannot find it. I want to make a histogram using breaks which are spaced exponentially and in

Generate a sequence of vectors of different length
Hi everyone After the following setup sector=2 # Define Number of Sectors sectors=LETTERS[seq( from = 1, to = sector )] # Name sectors No_ent=round(3/runif(sector)) # Number of entities per sector #Tot_No_ent=sum(No_ent) Goal is to get a List like (A1, A2, A3, B1, B2, B3, B4) where A is denoting an industrial sector and then a numbered sequence of companies within the sector. The step

Data Cube in R from CSV
Hello I am at the moment trying to get to grips with a data cube in R, and I am increasingly wondering whether I am actually making things unnecessarily difficult for myself. The idea is that I have a data cube with three dimensions (so a 3D matrix): companies, figures, and years. So along the z axis the vectors are essentially time series, the horizontals are all about a single figure and the

renaming multiple columns + interpolating temperature series
Greetings R Users, I?m new to R but at least managed to read in multiple files: filenames <- list.files(path=getwd()) numfiles <- length(filenames) for (all_temp in c(1:numfiles)) { filenames[all_temp] <- paste(filenames[all_temp],sep="") assign(gsub("[.]ASC$","temp",filenames[all_temp]),read.delim2(filenames[all_temp],

accessing names of lists in a list
After importing multiple files to data.frames in R, I want to rename all their columns and do other operations with them. The data.frame names are not continuous like 1, 3, 4, 6. I could not find a way of creating a list of the data.frames and loop this and ended up putting them into a list first: # get all objects all.obj = sapply(ls(), get) # get data frames dfrs = all.obj[sapply(all.obj,
