Thanks to Henrik Bengtsson, Martin Maechler, Brian Ripley, Jeff Gentry and David Brahm for taking the time to answer my questions about INDEX files in R packages. My key take-aways were: 1) All of this will be changing a lot in R 1.7.0-to-be, so don't sweat the details. 2) Many people run R CMD build before they run R CMD check. I found this quite surprising. I did not realize that R

Hi, all, I've been converting code from S-Plus ("S" for short) to R for a few weeks. Here are some differences I've found, aside from the big well-known ones (scoping, models, data storage) and the contents of Kurt Hornik's FAQ section 3.3.3. Let me start with the ones that seem like serious bugs or deficiencies: 1) LETTERS[c(NA,2)] in S is

Hi, I asked this question 2 years ago, and would like to know if the answer has changed. In S-Plus, I build databases of many large objects. In any given analysis, I only need a few of those objects, but attach'ing the whole database is fine since objects are only read as needed. How can I do the same thing in R, without reading the entire database? One possibility is to treat

Hi, The result of rowsum() in R doesn't have the dimnames I'd expect, e.g.: > rowsum(matrix(1:12, 3,4), c("Y","X","Y")) [,1] [,2] [,3] [,4] 1 2 5 8 11 2 4 10 16 22 whereas S-Plus gives the more useful result: [,1] [,2] [,3] [,4] X 2 5 8 11 Y 4 10 16 22 This is because R's rowsum() code gives

Hi, Reading http://ssc.wisc.edu/~ahanna/20_newsgroups.csv after downloading it using data <- read.csv("20_newsgroups.csv",header=TRUE) throws this. Warning message: In scan(file, what, nmax, sep, dec, quote, skip, nlines, na.strings, : EOF within quoted string So, for example, the first line in the file is this. This column contains only such text. Is there a way read it ?

Also in assign() there some arguments lacking in R such as 'frame' and 'where', though I guess that 'frame' in S may be similar to 'pos' in R.

Yes. I tried that already. Not straightforward. data <- read.csv("20_newsgroups.csv",fill=TRUE,as.is=T,header=F, quote="", sep=",", encoding="UTF-8") This line does read it haphazardly. The emails in the column are split into multiple columns and there are several columns with just ?NA?. Totally 202 columns. And then I removed columns with NA?s and

Hello. My smbd dies with SIG11. This occurs in 1.9.18p10 as well in 2.0.0beta2. I've read the Samba archive and found the article "Re: 1.9.17p4 - SIGNAL 11 error ??" from Luke and recompiled it with "-g -g". Here the results: After a "smbclient -L localhost" or any other tries to connect to the server the server dies an --- output of "gdb smbd core"

I'm trying to have a linux client to identify users against a AD server (w2k3). I'm using ldap as winbind backend, but using files I get same errors: On 900 users, some of them aren't fully recognised: doing a "wbinfo -u" I see the user in the list, but a "getent passwd user" return nothing. More precisery, I can get the SID of the user, but winbind is unable to

Hello, R-devel! I posted to R-help, and (inappropriately) to R-bugs, this R/S-Plus difference: > LETTERS[c(NA,2)] in S is c("","B"), but in R is c("NA","B") Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at> wrote: > I think we do not want to change this. ... > R> is.na(LETTERS[c(NA,2)]) [1] TRUE FALSE > so we really have NA but it is

If the following two conditions are met: 1) all.x is TRUE 2) at least 1 row in y does not have a match in x then any character vectors in y will be coerced to be factors. Here is a simple example (previously provided on r-devel): > x <- data.frame(a = 1:4) > y <- data.frame(b = LETTERS[1:3]) > y$b <- as.character(y$b) > z <- merge(x, y, by = 0, all.x = TRUE) > z

Hi, I understand work is being done to improve read.table(), especially by Prof. Brian D. Ripley. I offer below a version that I wrote, in the hope some aspects of it may prove useful or at least inspire discussion. Be aware that my version differs in a couple fundamental ways that reflect my aversion to dataframes and factors. So it returns a list of vectors which are all character,

Hi, all! My project today is to write a speedy colSums(), which is a function available in S-Plus to add the columns of a matrix. Here are 4 ways to do it, with the time it took (elapsed, best of 3 trials) in both R and S-Plus: m <- matrix(1, 400, 40000) x1 <- apply(m, 2, sum) ## R=16.55 S=52.39 x2 <- as.vector(rep(1,nrow(m)) %*% m) ## R= 2.39 S= 8.52 x3 <-

Hi, When php3 module is compiled in apache, files in any directory will be interpreted by the parser and executed. This is a security breach. There is a way to correct this? Any comments?
