Full_Name: Barry Rowlingson Version: 1.6.0 OS: RH8 i386 Submission from: (NULL) (148.88.136.205) Strange things happen if I premultiply a difftime() object with a number. Example: > d1 <- difftime(Sys.time(),Sys.time()) > d2 <- 1 * difftime(Sys.time(),Sys.time()) > d3 <- difftime(Sys.time(),Sys.time()) * 1 > d1 Time difference of 0 secs - thats fine > d2 [1] 0

Dear All I am a complete novice when it comes to R. I have been sent some code which I need to run on a dataset. I have downloaded and installed R but I dont seem to be able to get the code to run. I was hoping someone on the list would be able to give me a 'translation' of what the code is trying to do and if there appears to be any errors in it. The code is; mental <-

I've just spent today trying to fix a Heisenbug... this function returns a linear interpolator function: interpOne <- function(xl,yl){ f = function(data){ t = (data-min(xl))/(max(xl)-min(xl)) return(min(yl)+t*(max(yl)-min(yl))) } return(f) } > k=interpOne(c(0,1),c(4,5)) > k(0.5) [1] 4.5 and this function uses the above to return a function that returns a piece-wise

Barry, Would you mind providing the necessary patch for this behavior?

I see some value in Duncan?s proposal to implement this as an extra package instead of a change to base R, if only to see if the idea has legs. I?m minded to do so myself using your suggestion, but is there a particular reason why you recommend using the remotes package instead of devtools? The latter seems to have the same functions I would need, and I believe it is more widely installed that

Hey all, I'm trying to join a Linux machine running CentOS 5, Samba version 3.0.23 to a Windows 2003 Active Directory. I can authenticate successfully against Kerberos, but I cannot seem to join the domain. I'm using instructions from this article

Hi Peter, The ssconvert tool (part of gnumeric) is very good at converting spreadsheets to csv-files. There is a wrapper in the "gnumeric" package on cran.

Thank you for interesting examples. I would find useful to document this behavior also in `?mean`, while `+` operator is also affected, the `sum` function is not. For mean, NA / NaN could be handled in loop in summary.c. I assume that performance penalty of fix is the reason why this inconsistency still exists.

Yes, both are rooted in age-old design infelicities (in which, basically, interactive expedience has taken precedence over consistency and generality). Unfortunately, they are quite difficult to rectify, because there are bound to be countless uses of, say, diag(5) as a 5x5 identity matrix which would break if it suddenly meant the 1x1 matrix(5) instead. We'd need a very carefully

Ummm oops. Magic pixies? It assumed all of CRAN was installed? Maybe I'll write something that could go in /usr/lib/R/bin/RUN that checks and gets deps, installs the package, and runs package::main, which I think is what the OP wants - you could do R CMD RUN foo_1.0.0.tar.gz and away it goes...

To download a package with all its dependencies and install it, use the install.packages() functions instead of 'R CMD INSTALL'. E.g., in bash: mkdir /tmp/libJunk env R_LIBS_SITE=libJunk R --quiet -e 'if (!requireNamespace("purrr",quietly=TRUE)) install.packages("purrr")' For corporate "production use" you probably want to set up your own repository

Creating an .exe file isn't necessarily difficult. The main problems are that you have to write and compile the C (or other) files. Otherwise, the complexity depends on the level of Inter Process Communication that's required. Simply starting R with some initial conditions, is easy. Even if you want to prompt the user to install missing packages, it isn't necessarily difficult. It
