Is it possible to print a data.frame without the row names? I checked ?data.frame, ?print, ?format and didn't see anything that helped. In the example below, I would just like to show the two columns of data and not the row.names 1:10. > a<-data.frame(1:10, 21:30) > a X1.10 X21.30 1 1 21 2 2 22 3 3 23 4 4 24 5 5 25 6 6 26 7

All, I have managed to download files from web sites and ftp sites using R, so just for fun I tried to do so from the SEC's ftp site using the following code: ftp <- "ftp://anonymous:test at ftp.sec.gov/edgar/full-index/company.idx" download.file(url=ftp, destfile="test.txt") And it does not work. R says it cannot open the URL. If I paste the ftp part into IE it

Apologies for a naive question: Can R be installed and run on a server (operating system Windows Server 2008)? Thank you! -- Dimitri Liakhovitski

I want to use R to run dos commands (either by create batch files or using shell())and I need to write double quotes on the file (or shell command). As an easier example, lets take: > print("hello 'hello' hello") [1] "hello 'hello' hello" Lets say instead of the above, I wanted: "hello "hello" hello" If possible, how would I do that? I

I have not been able to figure out how to change the font size for R2HTML::HTML output. Or for output from prettyR::htmlize. If anyone can give me a couple hints that would be great. Thanks, Roger J.

I would like to learn how to parse a mixed text/xml document I downloaded from the sec.gov website (see example below). I would like to parse this to get the value for each xml tag and then access it within R, but I don't know much about xml so I don't even know where to start debugging the errors I am getting in this example code. Can anyone help me get started? Thanks, Roger ftp

I have a matrix called mat and y is the column number of my response and x is a vector of the column numbers of my terms. The variable name of y can change, so I don't want to hardcode it. I can find out the name as follows: > names(mat)[y] [1] "er12.l" Then I can run the regression by hard coding the variable name as follows: > mod <-

I have a character string and I would like to remove the leading and tailing white spaces. The example for 'sub' shows how to remove the trailing white spaces, but I still can't figure out how to remove both trailing and leading white spaces because I can't find any documentation for what "+$" means or what "\\s+$" means. Maybe its because I don't have a

All, I have a variable called `go` and it has a single quote in the name column of line 47 that I am trying to get rid of.

Dear List, on www.r-project.org, the title says 'The R Project for Statistical Computing'. but what exactly is the definition of statistical computing?

I am an R user trying to get around the 2Gig memory limit in Windows, so here I am days later with a working Ubuntu, and R under Ubuntu. But - the memory problems seem worse than ever. R code that worked under windows fails, unable to allocate memory. Searching around the web, it appears that the problem may be the ability to find contguous memory for my big vectors, but a fresh boot of

I created a small example to show something that I do a lot of. "scale" data by month and return a data.frame with the output. "id" represents repeated observations over "time" and I want to scale the "slope" variable. The "out" variable shows the output I want. My for..loop does the job but is probably very slow versus other methods. ddply

All, I am not understanding the scoping used in foreach when it is used inside a function. I keep getting "could not find function" errors for functions that are in memory when I try to use foreach within a function call. I have a simple example below. "testFun" is in memory and works when called by foreach directly, but when I place foreach in a function called

All, I have a function that runs a set of regressions (using the rlm function) and I notice that it run much slower on my 64-bit R than it does on my 32-bit R. I guess the bigger bit size slows it down. Anyway, I looked into Rprof to see how I can speed it up. I saw that 78% of the total time is spent in [.data.frame, so I tried converting my data to a matrix using data.matrix, but then rlm

I am completely new to LaTeX and Sweave, so I am trying to follow the tutorial in the following link: http://www.r-bloggers.com/using-latex-r-and-sweave-to-create-reports-in- windows/ I installed MiKTeX 2.9 and TeXnicCenter, but I get a build error when compiler the example file: The two errors are: "Error: running 'texi2dvi' on 'test.tex' failed" and "R> !

I modified an example in the object.size help page to create a function I want to be able to run: "mysize" <- function() { z <- sapply(ls(), function(w) object.size(get(w))) as.matrix(rev(sort(z))[1:5]) } mysize() When I test the lines inside the function it works fine: > z <- sapply(ls(), function(w) object.size(get(w))) > as.matrix(rev(sort(z))[1:5])

I am trying to create plots within a for loop and output them to a pdf. Here is a working example using plot: gg <- data.frame(datadate=1:4, spread=5:8) pdf() for (i in 1:3) { plot(gg$datadate, gg$spread, main=i) } dev.off() I am trying to learn more about ggplot2 so I try a slight modification and it doesn't work.

All, I am trying to post text from an XLS spread to my wiki and I need to remove any characters that are not UTF-8. Is there an easy gsub command that can do this?

Quantstrat useRs, I have a number of questions about how to use quantstrat that I have accumulated since I have begun playing with it. First, can the orderqty be dynamic? All of the examples I have seen are based on placing an order for 100 shares when a rule is triggered. Is it possible to set it up to buy the maximum number of shares given the starting or current equity? Similar to that

Hi All, I have a 8000*8000 matrix and I want to print out a file with the row name, column name and the value for those point with values satisfying a condition. I tried using a for loop, however, it took me forever to get the result. Is there a fast way to do this? Thanks!
