I found an interesting email that got caught in my spam quarantine. I?m wondering if dovecot is vulnerable to this kind of code execution (I?m aware that other components could be vulnerable, but this question is specifically targeting dovecot). The idea is to insert shell commands into various header fields that would get executed as part of the message processing/delivery. Examples include:

Hello list members I have a problem with modifying a data.frame. As an example given is a data.frame called ex : ex<-data.frame(id=c(1,2,3,4,5,6),obs=c(14,9,20,36,55,47),eff=c("A","A","B","C","C","C")) After that I would like to modify the object ex with the following short script: for (i in ex) { if(ex[i,3]=="A"||

Hi everybody I have found something (for me at least) strange with duplicated(). I will first provide a replicable example of a certain kind of behaviour that I find odd and then give a sample of unexpected results from my own data. I hope someone can help me understand this. Consider the following # this works as expected ex=sample(1:20, replace=TRUE) ex duplicated(ex) ex=sort(ex) ex

All, Is there an efficient way to apply say "mean" or "median" to a dataframe according to say all combinations of two variables in the dataframe? Below is a simple example and the outline of a "manual" solution that will work but is not very efficient (could also generalize this to a function). Searched the archives and docs but didn't see anything close to

Many thanks for the recent answers to my question about pattern recognition. The hint to "grep" and the "pattern" argument brought me a big deal forward. # Now, I have a data frame: DATE <- c("1930-01-01", "1930-01-01", "1930-02-01", "1931-01-01", "1931-02-01", "1931-03-01") # almost all months until

I have been trying out R-1.6.0 tarballs (2002-9-10 and 2002-9-17) on: arch sparc os solaris2.8 system sparc, solaris2.8 status beta major 1 minor 6.0 year 2002 month 09 day 17 language R As you see form above, R-1.6.0 compiles fine and works. However, when I "make fullcheck" I get the following error: running code in 'tools-Ex.R' ... OK

Esteemed R UseRs, Regarding specifying arguments in functions and calling functions within functions: ## beginning ## ## some data ex <- rnorm(10) ex[5] <- NA ## example function Scale <- function(x, method=c("mean", "median")) { scl <- method scl(x) } ## both return NA Scale(ex, method=median) median(ex, na.rm=FALSE) ## both return the median Scale(ex,

Hola! I had my hard disk and cpu fried, so had to reinstall debian from scratch, and now I have problems compiling R R-2.14.0. My system is wheezy with Xfce4 desktop. (-amd-64) ./configure make runs without problems, but make test dose not! Here is some of the output from make test: kjetil at kjetil:~/R/R-2.14.0$ make check make[1]: Entering directory `/home/kjetil/R/R-2.14.0/tests'

Hi! I am using R version 2.7.0 and am working on a panel dataset read into R as a dataframe; I call it "ex". The variables in "ex" are: id year x id: a character string which identifies the unit year: identifies the time period x: the variable of interest (which might contain NAs). Here is an example: > id <- rep(c("A","B","C"),2) >

How do I tell the optimizer that the (dereferenced) value of an i8** parameter is NULL at the start so that it can eliminate the check? I have code like: void test2(void** ex) { printf("go\n"); // does not change *ex } void call2(void** ex); void testeh(void** ex) { // I want to tell the optimizer *ex is null so it can eliminate the first

I have installed both 32-bit and 64-bit versions of R2.12.0 (2010-06-15 r52300) on my Ubuntu 10.04 64-bit system. I observe the following behavior when running the examples from base::connections. There appears to be a problem with seek() on a .gz file when using a 32-bit installation of R2.12.0, but the problem doesn't appear in the 64-bit installation. I realize that seek() has been

Hello All, Am I misreading the documentation? The text.rpart documentation says: "label a column name of x$frame; values of this will label the nodes. For the "class" method, label="yval" results in the factor levels being used, "yprob" results in the probability of the winning factor level being used, and ?specific yval level? results in the probability of

Hi, at the R prompt, is it possible to retrieve the last error (as in condition object of class "error")? I'm not asking for geterrmessage(), which only returns the error message (as a character string). I'm basically looking for a .Last.error or .Last.condition, analogously to .Last.value for values, which can be used when it is "too late" (not possible) to go back

uname -a => SunOS frege 5.9 Generic_112233-04 sun4u sparc SUNW,Sun-Blade-100 Today I downloaded R-1.7.1.tgz, unpacked it, did ./configure and ran make. All apparently went well. Then I did make check. On rerunning make check (because I forgot to save the output the first time), I get f% make check `Makedeps' is up to date. `base-Ex.Rout' is up to date. `ctest-Ex.Rout' is up to

Hello R users, I am trying to calculate the stochastic lambda for a published matrix population model using the popbio package. Unfortunately, I have been unable to match the published results. Can anyone tell me whether this is due to slightly different methods being used, or have I gone wrong somewhere in my code? Could the answer be as simple as comparing deterministic lambdas to

Dear R People: I thought all was well with my source compilation on Windows until I tried "make check" Here is an abbreviated version of my results: C:\esr\R-2.5.0\src\gnuwin32>make check make check -------- Testing package base -------- Running examples in 'base-Ex.R' ... Comparing `base-Ex.Rout' to `base-Ex.Rout.prev' ...diff: extra operand

Hi All, I'm trying to install R from source on an Intel machine running Linux (RedHat 6.2) and I am getting errors (Error 139, Error 2, and Error 1) on 'make check'.
