similar to: backslash in character string?

Dear list, I am trying to replace Unicode notation of German and Spanish special characters (as read in by read.csv from excel spreadsheets) by character strings that can be interpreted by LaTeX. E.g.: uni2latex <- function(x){ x <- gsub("&", "et", x, fixed = TRUE) # Deutsch x <- gsub("\u0080", "\\\"A", x, fixed = TRUE) x

Dear all, I was testing the wonderful package APE. However upon testing a particular Newick's format tree - which I think to be a non-binary tree - it yields different result as expected. > library(ape) > tree.hiv <- read.tree(text="(rat,mouse,(human,chimp));") > is.binary.tree(tree.hiv) [1] TRUE Was that a bug in APE package? - Gundala Viswanath Jakarta - Indonesia

Dear list, I want to run latex from an R script: system("latex mysource.tex") or: texi2dvi("mysource.tex", pdf = TRUE, clean = FALSE, quiet = TRUE, texi2dvi = latex) but latex does not seem to be on the search path: /bin/sh: line 1: latex: command not found. Although 'printenv PATH' tells me that the usr/texbin is looked for executables:

I do the these passages: library(Geneland) set.seed(1) data <- simdata(nindiv=200, coord.lim=c(0,1,0,1) , number.nuclei=5 , allele.numbers=rep(10,20), IBD=FALSE, npop=2, give.tess.grid=FALSE) geno <- data$genotypes coord <- t(data$coord.indiv) path.mcmc <-

Dear list, I'm trying to download a text file directly from the internet using the RCurl package and the command getURL. Duncan Lang graciously helped me solve the first step in this problem using the following command: ################# txtfile <- getURL('ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho/13e19.txt', ftp.use.epsv = FALSE) #################

Dear list, I'm trying to write my first looping function in R. After many hours of searching help files and previous posts, I'm at wits end. Please forgive my programming ignorance...any help is greatly appreciated. I need to sort through a vector (x) and identify the point at which 2 successive values become smaller than the previous value. I've written a "while"

Dear List, I'm stuck on what seems like a simple indexing problem, I'd be very grateful to anyone willing to help me out. I queried a dataframe which returns a character vector called "plot". I have another dataframe from which I want to subset or select only those rows that match "plot". I've tried subset, and also the "which" command. plot

Dear list, I've recently installed R on a 64 bit machine with 8 GB of RAM. I set this computer up as a dual-boot system, with windows XP 64 and Ubuntu 7.10. I downloaded the Linux 64 bit version of R and installed it. I'm trying to run rather large Random forest models and was running into severe memory limitations with my old windows 32 bit machines. When I run Random Forest models

Greetings R list, I am stuck on a simple syntax problem. I want to list all files in a directory, excluding files of a certain type. I have tried pattern matching as follows: a <- list.files(data, full.name = TRUE, pattern != ".xml") # exclude all .xml files The warning returns that my syntax is incorrect. I have read the regexpr help files and search old posts to no

Dear list, I am trying to download a text file from an ftp site using download.file(). I used the following code: url <- "ftp://ftp.wcc.nrcs.usda.gov/data/snow/snow_course/table/history/idaho/13e19.txt" dest <- "c:/test/downloadtest.txt" download.file(url, dest) I get this error message, indicating that R is unable to open the connection: trying URL

Dear list, I would like to plot 2 series of numbers with very different ranges/scales as lines on the same plot. I assumed this is commonly done and easy, but I have not found any help files (e.g. axis() or matplot() that show how. I've searched many old posts to no avail. I'll be very grateful for any suggestions on how this is done. Best, Zack

Dear R wizards, I have a folder containing 1000 files. For each file, I need to extract the first row of each file, paste it to a new file, then write out that file. Then I need to repeat this operation for each additional row (row 2, then row 3, etc) for 23 rows in each file. I can do this with a for loop (as below). Is there a way to use some of the indexing power of R to get around this

Dear list, I'd like to use path.analysis in the package agricolae in batch format on many files, retrieving the path coefficients for each run and appending them to a table. I don't see any posts in the help files about this package or the path.analysis package. I've tried creating an object out of the call to path.analysis, but no matter what I try, the function automatically prints

Dear list, Below I've written a clunky for loop that counts NA's in a row, replacing all with NA if there are more than 3 missing values, or keeping the values if 4 or more are present. This is sample code from a very large dataframe I'm trying to clean up. I know there are many simpler more elegant solutions to this little problem. Would someone be willing to show me how to

Hi list, The function is.integer tests if an object is of type integer: see e.g.: is.integer(12) # FALSE is.real(12) # TRUE mode(12) # "numeric" But how can I test if a number is actually an integer? R seek is difficult to search in this case because it mainly yields entries about the integer()-function family. Thanks for any hint! Christoph Heibl

Dear list, I'm trying to query a string of numbers to identify where in the string the numbers stop increasing (where x[i] == x[i+1]). In example 1 below, I've adapted code from Jim Holt to do this. However, I run into situations where the condition is not met, as in example 2, where the number string is continuous. In this case, I need to specify an alternative outcome, where if in the

Hello, This must be simple... Thanks a lot - Christoph # Imagine you have a list, e.g: K <- list(1:10, 2:11, 9:18) K # Transforming to dataframe... KK <- as.data.frame(K) # ... one obtaines the list elements as column. KK # But I need the list elements as rows # How can I achieve this? Is there a simple way to transpose data.frames?

Hi guys, I can't see virtio in releng/9.1, is there any particular reason why it isn't going to be included given that it works reasonable well (and is optional anyway, so not likely to be detrimental)? Thanks, Joe
