similar to: error in scan(...

Hello, I got some of the R source code and not being able to Run it in RStudio. I get the error: Error in setwd("dir") : cannot change working directory I have gone through forums but nothing seemed relevant to my issue. What bugs me the most is the ("dir") that the error shows, is of those who wrote the source code and not mine(it still sees the directory of their

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

It seems to me the following should work (in fact, it comes from someone's SPlus file). Instead, it reads the first 8 lines and then spits out syntax errors. Using nlines=36 works. Using nmax does not. Intel RH5.2 with R90.0. Debugging shows it must be internal. Jim junk <- scan(file="",list(i=0,r1=0,r2=0,lull="",day=""),n=5*36) 1 3 5 no 1 2 1

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,

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",

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,

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)

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 all, I have a tab-delimited text (.txt) file which I'm trying to read into R. This file is of column format - there are in fact 3 columns and 259201 rows (including the column headers). I've been using the following commands, but receive an error each time which prevents the data from being read in: > Jan <- read.table("JanuaryAvBurntArea.txt", header=TRUE) Error in

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 <-

I'm using scan in a script to record a series of responses of the user as a function of some graphs that I put up on the screen. A toy version would be, y <- rep(NA, 3) for (ix in seq( length(y) ) ) { y[ix] <- scan( n = 1 ) } However, if I include any code after this loop, for example, y <- rep(NA, 3) for (ix in seq( length(y) ) ) { y[ix] <- scan( n = 1 ) } y I get an error

I have been having problems with using scan(). I searched the archives and found someone with the same problem several years ago, but did not find a solution. I want to prompt the user for input, scan in that input, and then go on to use it as a variable. The simplest version of my program is cat("enter m","\n") m <- scan(n = 1, quiet = T) m If I enter these lines one

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 = >

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

Dear Experienced R Practitioners, I have 4GB .txt data called "dataset.txt" and have attempted to use *ff, bigmemory, filehash and sqldf *packages to import it, but have had no success. The readLines output of this data is: readLines("dataset.txt",n=20) [1] " "

Hola Jorge, Algo pasa con el fichero... He abierto el link de Dropbox, y he salvado el texto como "txt.txt" en local. Pruebo a abrirlo en R y...: > scan(file="txt.txt")Error in scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : scan() expected 'a real', got 'ÿþM'> getwd()[1] "C:/Users/xIs12136/Downloads" Pruebo a abrirlo

Hi folks, I followed an online example to input data; > x = scan(1,2,3,4,5) Error in scan(1, 2, 3, 4, 5) : either specify 'nmax' or 'n', but not both. It can't work. > x = c(1,2,3,4,5) > x [1] 1 2 3 4 5 It works. Whether "scan" is replaced with "c" ? > ?c ..... Usage: c(..., recursive=FALSE) TIA B.R. Stephen L

Hola. Con r <- scan(txt, character(0)) creo que debiera montarse el texto carácter a carácter. He comprobado que funciona pero no he validado la importación del texto.
