Hi, I'm trying to use pipes in R. By now, I could launch the linux command "wc" (to count words from a text), but I don't know how to capture the results, say in a vector of chars... Here is the R code I'm trying: :> f <- pipe("wc", open="w") :> writeLines(c("uno dos tres", "cuatro cinco", "seis"), f) :> close(f)

Dear list, I am trying to find a fast solution to read moderately large (1 -- 10 million entries) text files containing only tab-delimited numeric values. My test file is the following, nr <- 1000 nc <- 5000 m <- matrix(round(rnorm(nr*nc),3),nr=nr) write.table(m, file = "a.txt", append=FALSE, row.names = FALSE, col.names = FALSE) scan() is faster than

Thomas, As F Harrel in a preceding message told me that you are the maintainer of Hmisc package, I write directly to you, with copy to the Rhelp list in case someone encountered the same problem and find some benefit in the response. I used quite often the function sas.get in Hmisc library which I is very, very useful. But, as trying to reuse it today it seems not to function anymore. I tried

Hello, I encountered some unexpected behavior of unzip when using info-zip's unzip instead of R's internal program. Specifically, unzip("file.zip", list=TRUE, unzip=/usr/bin/unzip) produces incorrect output if the zip archive has filenames with spaces, and results in an error if the zip archive includes an archive comment or file comments. Here is some code to reproduce along

Hi again! While investigating the bug report [*] I found out that on unix, system2 does not quote its `stdin` argument while preparing the command line to launch. It does shQuote the `stdout` and `stderr` arguments, and also the `f <- tmpfile()` variable (which is used if `input` argument is provided), which seems to set a precedent. On Windows, stdin, stdout, and stderr are handled

Is it just me, or did a corrupt PACKAGES.gz file get installed in the bin/windows/contrib/3.2 directory of CRAN mirrors recently? gzfile() complains about it and Cygwin's gzip cannot decompress it. I tried the following repos <- "https://cran.rstudio.com" v <- "3.2" pkgs.gz <- paste(sep="/", repos, "bin/windows/contrib", v,

I have 3 SAS files all in the directory F:/sas, two data files and a format file : form.ea1.sas7bdat form.ea2.sas7bdat sas.fmts.sas7bdat F is a USB. I am trying import them to R using "sas.get". I have not used SAS since I was downloading data from mainframe and having to write JCL. I had forgotten how bizarre SAS can be. I currently have not even figured out how to load the files

I tried implementing my * and it didn't pass the spouse factor at this time. I wanted to hook it up for outbound only at this point to get a better handle on the dial plans and the echo problem. I thought this might have been done before as a natural part of testing - but maybe not. In wcfxo.c I found this: if (!wc->offhook && !wc->ringdebounce) { if

Dear R-users, It is my understanding that cat(shQuote(a.string)) should print the origintal a.string. Is this right? I am not sure cat() correctly prints strings which are generated by triple-shQuote(): > shQuote(shQuote("a")) [1] "\"\\\"a\\\"\"" > cat(shQuote(shQuote(shQuote("a"))), '\n')

Hello, I wanted to ask help about importing sas datasets. 1)I tried with some functions as read.ssd (foreign package), but it doesn't import the file if the length of the variables' names are longer than 8 bite (it has to conform to the 6 version). 2)I then tried with the sas.get function (Hmisc package) but with the command: c<- sas.get(lib="c:\\ghan",

Hi, I'm aware of the definition of a "valid filename" in .SweaveValidFilenameRegexp, but I think it might be better to quote the filename when it contains spaces instead of just giving a warning. This should bring us safer LaTeX code (although I never use spaces in paths). Here is the simple patch: Index: src/library/utils/R/SweaveDrivers.R

Just a minor point in the suggested solution: df$LAP <- with(df, ifelse(G=='male', (WC-65)*TG, (WC-58)*TG)) since WC and TG are not conditional, would this be a slight improvement? df$LAP <- with(df, TG*(WC - ifelse(G=='male', 65, 58))) -----Original Message----- From: R-help <r-help-bounces at r-project.org> On Behalf Of Jorgen Harmse via R-help Sent: Friday,

When buffered write fails to copy data into underlying page cache page, ocfs2_write_end_nolock() just zeroes out and dirties the page. This can leave dirty page beyond EOF and if page writeback tries to write this page before write succeeds and expands i_size, page gets into inconsistent state where page dirty bit is clear but buffer dirty bits stay set resulting in page data never getting written

We connected an * box with an e100p to an E1/PRI from a telco here in Italy. After we had it working perfectly the telco told us that, despite the circuit appeared to work fine, and we could place calls on it, they had an "E-bit2 alarm indication constantly on that caused the circuit to be flagged as "faulty" every time. (The E-bit indication, is an alarm sent back from us to

I'm using R 1.8.1 on Red Hat Linux 9. I've worked out the linear model decomposition by hand. Using "aov" with "Error" to fit a split-plot model, I get very different results depending on whether I use the "data" argument for "aov" or not. When I use the "data" argument, the ANOVA table from "summary" is correct but the
