When I attempt to install the online help for R.99 on Intel RH5.2, I get the following message Substitution loop at /usr/local/src/R/etc/Rdconvlib.pl line 1589, <rdfile> chunk 171 and it stops after a few files. Each time I rerun it, it gets a bit further and gives a different number at the end. I commented out the line 1589 and it works.

Dear R-users, When i try - Data1<-read.table("/Users/kama/Analysis/GDP10.csv",header=TRUE,sep=";") i am getting this error: Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : number of items read is not a multiple of the number of columns I wonder what Iam doing wrong. i guess it is something simple, however, i do not understand

Hi, I am looking for an efficient way of skipping big chunks of lines on a connection (not necessarily at the beginning of the file). One way is to use read lines, e.g. readLines(1e6), but a) this incurs the overhead of construction of the return char vector and b) has a (fairly remote) potential to blow up the memory. Another way would be to use scan(), e.g. scan(con, skip=1e6, nmax=0)

I'm trying to import a table into R the file is about 700MB. Here's my first try: > DD<-read.table("01uklicsam-20070301.dat",header=TRUE) Error: cannot allocate vector of size 15.6 Mb In addition: Warning messages: 1: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : Reached total allocation of 1535Mb: see help(memory.size) 2: In scan(file, what,

With 0.64.1 on Intel RH5.2, abc <- list() abc$abc$abc <- matrix(1:20) mt <- terms(~(abc$abc$abc[,1]==64)|(abc$abc$abc[,1]==65)|(abc$abc$abc[,1]==75) |(abc$abc$abc[,1]==84)|(abc$abc$abc[,1]==85)) model.matrix(mt,model.frame(mt)) crashes. With ab$ab$ab, it does not. Apparently, the bug I reported for 0.64.0 has just been pushed back one step. Jim

Well here is my (first) segmentation fault for this version (R0.90.0) on Intel RH5.2: x <- matrix(0,nrow=1,ncol=3) y <- c(0.1,10,0.01) rbind(x,y) Jim -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.- r-devel mailing list -- Read http://www.ci.tuwien.ac.at/~hornik/R/R-FAQ.html Send "info", "help", or "[un]subscribe" (in the

The following works: list(function() 1, function() 2) but this does not: z <- list() zz[[1]] <- function() 1 giving an "incompatible types" error.

Hello, All: I have a 4.54 GB file that I'm trying to read in chunks using "scan(..., skip=__)". It works as expected for small values of "skip" but goes into an infinite loop for "skip=1e11" and similar large values of skip: I cannot even interrupt it; I must kill R. Below please find sessionInfo() with a toy example. My real problem is a large

A user has crashed R90.1 on MS Windows by succesive calls to two of my formula/function interpretors in an order that I had not foreseen. I have checked and this also occurs with Intel RH5.2. I have distilled the problem down to its bare bones as the following set of instructions: func <- function(.mu){ .ch1 <- deparse(.mu,width=500)[-1] .fn <-

I found it easy to use R when typing data manually into it. Now I need to read data from a file, and I get the following errors: > refdata = > read.table("K:\\MerchantData\\RiskModel\\refund_distribution.csv", header > = TRUE) Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : line 1 did not have 42 elements > refdata = >

I know it's a common error and there is a lot of help available but still can't resolve the issue: all i am trying to do is to read a csv file from my folder and this is what i get: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : scan() expected 'a real', got '1,m,a,F,165,240,26.5,31,0.738,0.704,1.095,0.606,0.847' Can you help? -- View

Hi, Since C++ code compiled with g++ 4.6.3 on Windows (the version included in latest Rtools) now can produce things like '1.#IND' when writing doubles to a file (using the << operator), I wonder whether scan() shouldn't support those things. Right now (with recent R devel and latest Rtools) we get errors like: Error in scan(file, what, nmax, sep, dec, quote, skip, nlines,

I was getting worried. 0.65 is the first version that I had not been able to crash. Well the following gives a seg fault on Intel RH5.2 with R0.65.1: plot(rnorm(20),xlab=expression(mu[Inf])) You can guess what I was trying to do, as I used infty first and that did not work. (I now know the correct formula.) Jim -.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-.-

Hi Everyone, I am new R user and am trying to learn by reading the online manual "An Introduction to R" from the R web site. I am trying to practice using the scan() function as explained in the manual. For this I first created three vectors (one a character vector and two numeric one) and saved file "input.dat" in my working directory as: > label <- c("Bill",

Hello R-User I have a table as tab-delimited textfile (291 rows, 83 columns). The first row are labels and the first line the variable names. I used the following code several times with different similar tables and it always worked. But now: setClass("of") setAs("character", "of", function(from) as.ordered(from)) Classe82<-cclasses <-

Full_Name: Dr. Alex Sheppard Version: 2.7.1 OS: Linux Debian Lenny Submission from: (NULL) (79.73.224.62) After scanning from an open (text) connection, then seeking, then scanning again, the second scan returns incorrect result. It looks like the first byte scanned was from the pre-seek file position, then it continues to read from the post-seek file position. To reproduce: #Put 3x3 matrix

Dear R-users, I have encountered the following problem every now and then. But I was dealing with a very small dataset before, so it wasn't a problem (I just edited the dataset in Openoffice speadsheet). This time I have to deal with many large datasets containing commuting flow data. I appreciate if anyone could give me a hint or clue to get out of this problem. I have a .dat file
