Can anyone tell me how to get R to include a double quote in the middle of a character string? For example, the following code is close: > fnd<-"Open fnd 'test'" > cat(fnd) Open fnd 'test'> > But instead of Open fnd 'test' I need: Open fnd "test". Difference seems minor, but I am writing batch files for another

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

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 <-

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

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

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. I have tried using gsub, but I cannot get the syntax correct to tell R to remove the ' (single quote). > go[47,] gvkey Symbol Name Rank MarketCap MemoDate Action Analyst Reason SharesHeld 75 065105 BJ BJ'S WHOLESALE CLUB INC 0.9579

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.

First I have a matrix called stocks1: > class(stocks1) [1] "matrix" Here are the first 5 rows of the last 4 columns: > stocks1[1:5,2:5] [,1] [,2] [,3] [,4] [1,] 80.73 31.95 25.4 25.69 [2,] 83.66 31.95 27.12 25.2 [3,] 83.27 32.93 28.74 26.29 [4,] 83.9 34.07 29.77 26.6 [5,] 82.74 35.18 30.24 27.41 Now, why can't I convert this into a dataframe?

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 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 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

It took me some time to find this bug in my code. Is this a feature of R? Am I doing something wrong? > a=data.frame(x=1:10,y=1:10) > b=data.frame(x=11:20,y=11:20) > z=data.frame(1:10,11:20) > a$z=z > b$z=z > rbind(a,b) Error in `row.names<-.data.frame`(`*tmp*`, value = c("1", "2", "3", "4", : duplicate

Dear All, is there a simple way to print a data.frame without its row.names? example: datum <- as.Date(c("2004-01-01", "2004-01-06", "2004-04-12")) content <- c('Neujahr', 'Hl 3 K.', 'Ostern') df1 <- data.frame(datum, content) print(df1) datum content 1 2004-01-01 Neujahr 2 2004-01-06 Hl 3 K. 3 2004-04-12 Ostern Can I get

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? (I previously sent this same email to r-sig-gui. That was a mistake and I apologize for the duplication.) Thanks, Roger J.

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

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 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

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])
