similar to: write.csv suggestion

The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep,

Dear R developers, It would be great if you could implement the two minor code changes suggested below, which would help processing large objects in R. Jens Oehlschl?gel # Wish no. 1: let [.AsIs return the class AFTER subsetting, not the class of the original object # Wish no. 2: adjust write.csv and write.csv2 for multiple calls in chunked writing # Rationale no. 1: a couple of packages

Attempting to write a vector to a csv file without column headers does not work as documented. The col.names=false feature on the write.table command does however work and it can thus be coerced

Hello, For reasons I don't understand, data() imports CSV (Comma-Separated Values) as if they were delimited by semicolons instead of commas. (Are semicolon-separated Comma-Separated-Value files common somewhere?) Given that this is the case, if I choose to put comma-delimited CSV files in my data directory, what is the preferred method of loading these into memory?

Thanks to all who have responded. My concern was to be able to write a csv file that can have line feeds in string columns chr(10). Why? Excel allows line feeds chr(10) within cells and line breaks chr(13)+chr(10) at line ending, but the windows version of R automatically replaces \n by \r\n in writing and \r\n by \n in reading (text mode). The clues for a solution came from Brian Ripley and

hallo, i have a problem by writing a csv file the first colum is filled with index numbers from 1 to n. i have to unique two csv files once a week while one file is always the same. can anybody tell me, how to write the dataset into a csv file without the first row of the indexnumbers. x[,-1] does not wok as it eliminates the first "interesting" colum. col.names is not accepted by r

Using write.table i would like to save data as an excel file to a folder. I am not too sure how to write the file path or what to name the file. I would appreciate any feedback. > write.table(x, file = "", append = FALSE, quote = TRUE, sep = " ", + eol = "\n", na = "NA", dec = ".", row.names = TRUE, + col.names =

Hi all, I have a problem to read csv file with comma as decimal. The numbers were readed as strings. I used the following string in R, but I do not understand why it does not work. tab <- read.csv2("Specimen_RawData_1.csv", header = TRUE, sep = ";", dec = ",", nrows = -1) In addition, I copy/past into the post the link to the csv file generated by my instrument.

Dear all, I have some encoding problem which I'm not familiar with. Here is the case : I'm read data files which can have been generated from a computer either with global settings in french or in english. Here is an exemple ouf data file : * English output Time,Value 17,-0.0753953 17.05,-6.352454E-02 * French output. Time,Value 32,-7,183246E-02 32,05,3,469364E-02 In the first

I'm running R 2.11.0 on a 32-bit Windows XP machine. Whenever I try to write a csv file with 'append' set to TRUE, I get this message: attempt to set 'append' ignored. Obviously, this is no good, since R is deleting my previously saved data files, rather than appending to them. What can I do to fix this? -- View this message in context:

I've found several similar issues with write.table/read.table with Dates on this list, but trying to follow this advice I still get an error. First, I read in data from several files, constructing several date/time columns using ISOdatetime > str(Tall$Begin) 'POSIXct', format: chr [1:40114] "2005-10-02 00:00:00" "2005-10-02 00:00:00" ... > length(Tall$Begin)

Good day, The data function can import a variety of file formats, one of them being C.S.V. Problematically, all of the table columns are collapsed into a single data frame column. This occurs because "files ending .csv or .CSV are read using read.table(..., header = TRUE, sep = ";", as.is=FALSE)". I suggest that the semi-colon used as the column separator be changed to a

Greetings, When I try to use the write.table command to save a matrix as a file and then open the file with read.table, if I try to take the mean of the entire matrix, instead each column of the matrix has its mean calculated. I have copied and pasted an example of my code below. When I try to make the header false with the read.table command, I am given an error message. I would appreciate any

Thanks in advance for reading my question. This is my first time working with R, though I have some intro-level experience with other languages. I am writing a program that performs a certain set of calculations on each row of a list of data, and here's what I have so far: for (i in 1:2858) { Calc_1 <- some_stuff Calc_2 <- some_more_stuff Calc_3 <-
