similar to: xtable - caption missing with float=FALSE

All, I have a 30 million record text file without header information. I would like to add a header to this file without reading it first. Is this possible? The code below does what I want except that the readLines portion takes quite a long time. Is there a way around reading the lines? I'm working on Windows XP. Zev input<-readLines("c:/junk/forR.csv")

Hi R folks, Can anyone tell me how to read in a pipe ("|") delimited text file? I've tried the following: read.delim("c:/junk/junk.txt",sep="|", skip=7, check.names=FALSE,quote = "", header=F) The file looks something like the following: RD|I|04|013|9997|68103|5|7|017|830|20000221|00:00|12.6||6|||||||||||||

Dear All I am running Sweave with xtable and want to put the caption placement on top. But this does not work. Any idea what is going wrong? Here is an example that runs properly with the exception of the caption placement in the pdf-file. \documentclass[11pt,a4paper]{article} \usepackage{Sweave} \begin{document} <<>>= x = runif(100, 1, 10) y = 2 + 3 * x + rnorm(100)

Hi All, Can anyone direct me to a read function in R that will allow me to only read in rows of a text file that begin with a particular value such as the data below. I would read the entire file in and then limit, but the files were constructed such that the first two letters determine how many variables are in the row (different letters mean different numbers of columns and different

Hi All, Is there a simple way to convert a string such as c("A", "B" ,"C", "D") to a string of c("Group1", "Group1", "Group2", "Group2"). Naturally I could use the factor function as below but I don't like seeing that warning message (and I don't want to turn off warning messages). Perhaps a function

Hi R folks (Dr. Bates in particular), In August 2005, Dr. Bates mentioned that the documentation for lme4 "will be in the form of a book with the working title 'Multilevel Modeling in R'" and I'm just wondering if there is an estimated date of publication or if it's still a long way off. The Rnews article does a great job of introducing the package, but I'm

Dear R-users, please consider the following minimal example: \documentclass[a4paper,titlepage,onecolumn,12pt]{article} \usepackage[italian]{babel} \usepackage{amssymb} \usepackage[utf8x]{inputenc} \usepackage[pdftex]{graphicx} \begin{document} <<label=test, echo=FALSE, results=tex>>= df.data1 <- cbind.data.frame(A = rnorm(18), B =factor(rep(LETTERS[1:6],

Hola Tengo un problema con Sweave y xtable, concretamente quiero cambiar el color según un criterio, creo que es más fácil explicar con los siguientes ejemplos, uno puede correr directamente porque es R, al siguiente código hay que guardarlo como Rnw, y luego puede ser corrido en R, donde seguramente al correr este se darán cuenta de mis dos problemas porque saltan al abrir el pdf que se obtiene

Hi, I'm using Sweave with xtable to generate Latex tables. My problem is that some of the tables are too wide, and I would like to use the tiny font for these tables, but not for the others nor for the text. I can't work out how to accomplish that. The Latex code below does what I want it to, but I have to insert the "\tiny{" and the closing "}" by hand. It

Dear R users, The Sweave code below runs fine, as it is. However, an error occurs when the line 'library(xtable)' is uncommented: Error: chunk 1 Error in "label<-"(`*tmp*`, value = "month") : no applicable method for "label<-" Is anybody aware of this and knows a workaround? Thanks, Sander. *******************

Hi, I was trying to get hyperlinks using xtable, but couldn't get the hyperlinks to function properly. For example, if I use ## Try to link NY times website to every figure in column 4 mat <- matrix(1:43,6,5) mat[,5] <- "http://nytimes.com" for(i in 1:nrow(mat)){ strr <- paste('<a href="', mat[i,5],'">', mat[i,4], '</a>',

Hi, I had my R to MySQL 5.0 connection working fine under 2.5.1 on Windows XP. My MySQL installation is local, not on a server and I could connect with: con <- dbConnect(MySQL(), dbname = "mydatabase", user="root", password="XX") I have updated to R 2.8.1 (RMySQL 0.7-2) but that same line of code yields: Error in mysqlNewConnection(drv, ...) : RS-DBI driver:

Dear R users, I am new to Latex and I am using the R package xtable to generate tables. I want to produce a table that is very long. in the landscape format, but I would need to rescale the table so that it fits in the page. xtable enables me to have the landscape format, but I cannot rescale it, and there seems to be a problem, if I use scalebox in Latex on my output produced with stable and the

Hi, I'm working with Sweave and I have some trouble generating table. The R code is: print(xtable(myTable, caption ="", label="tab:myTab", digits=3), tabular.environment='tabular', floating=TRUE, caption.placement="top",size="\\scriptsize") and the resulting LaTeX table is: \begin{table}[ht] \begin{center} \caption{Principal

Hi, I'm using Sweave to prepare a descriptive report. Are at least 20 tables built with xtable command of kind: <<echo=F, results=hide>>= q5 = factor(Q5, label=c("N?o", "Sim")) (q5.tab = cbind(table(q5))) @ <<echo=F, results=tex>>= xtable(q5.tab, align="l|c", caption.placement = "top", table.placement='H') @ I'm

Dear R-users, I've enhanced the "xtable" package, adding numerous features that have been requested by users. The changes are listed below. The objective throughout has been to avoid any breaking changes. However, as "xtable" is widely used and is a dependency of many packages I'd like to have others try it out before I post it to CRAN. Both bug reports and design

Hello, I'm trying to put a dynamic table and a dynamic graph side by side in a pdf document using Sweave. The data.frame used to generate the table is called rg (rg.txt): "Date"; "Code"; "Data1"; "Data2" "2009-03-10";"1";1958;147 "2009-03-10";"2";302;144 "2009-03-10";"3";4;141

Hi, I saw this example for 2.10 Time series in the xtable gallery documentation. http://cran.r-project.org/web/packages/xtable/vignettes/xtableGallery.pdf How would I add a column at the end "Total" which sums the row, with minimal changes to the code below? Thanks in advance. - Ken 2.10 Time series > temp.ts <- ts(cumsum(1 + round(rnorm(100), 0)), start = c(1954, + 7),

Hi: I am trying to create a dynamic latex table using \Sexpr{} but it's not evaluating it. I also tried the example below without Sweave and also fails. I have also copied the Sweave.sty to my working directory but nothing seems to work. Do I need to have certain package in order to run \Sexpr{}? \documentclass[a4paper]{article} \usepackage{C:/R/R-2.8.1/share/texmf/Sweave} \begin{document}
