...l, all.equal is generally very useful when you want to find the differences between two objects. It breaks down however, when you have two long strings to compare: > all.equal(a, b) [1] "1 string mismatch" Does any one know of any good text diffing tools implemented in R?

Hi all, Is there a fast way to determine the number of lines in a file? I'm looking for something like count.lines analogous to count.fields. Hadley -- http://had.co.nz/

Hi all, Is there any chance that readRDS and saveRDS might one day become read.rds and write.rds? That would make them more consistent with the other reading and writing functions.

Hi all, Am I using the correct syntax to set a custom R_LIBS when running R CMD INSTALL from the command line? I get: R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/ # Desktop : R_LIBS=/Users/hadley/R-dev R CMD INSTALL aL3xa-rapport-08e68ca/ # * installing to library ?/Users/hadley/R? # ERROR: dependency ?ascii? is not available for package ?rapport?

Hi all, Are there base functions that do the equivalent of this? fliptb <- function(x) x[nrow(x):1, ] fliplr <- function(x) x[, nrow(x):1] Obviously not hard to implement (although it needs some more checks), just wondering if it had already been implemented.

Hi all, Would someone mind pointing to me to the inspiration for the use of the L suffix to mean "integer"? This is obviously hard to google for, and the R language definition (https://cran.r-project.org/doc/manuals/r-release/R-lang.html#Constants) is silent. Hadley -- http://hadley.nz

...emember the details. Maybe someone else can comment. (I am a bit busy at the moment.) If no one supplies the information in a few days I will try to take a look. In the meantime you can start your reading on-line. :-) Regards, Eric Dear Eric, I downloaded the material from https://github.com/hadley/adv-r as a zip file and decompressed it. But, how to build the book from this? The directory book contains a R-script buildbook.R. I downloaded all packages that are required, but the script does not run. Is there an additional script required? Best, Albrecht -- Albrecht Kauffmann alkauffm a...

Is it conceivable that Julia could be ported to use R syntax in a way that would allow the vastly larger numbers of R programmers to seamlessly switch? Or equivalently, could an iteration of R itself do this?

Hello all, Can anyone recommend any free(ish) Ruby photo album components? Preferably something with a user structure built in. Cheers. -- Posted via http://www.ruby-forum.com/.

...s in R? is.recursive defines them as by exclusion: "most types of objects are regarded as recursive, except for vector types, ?NULL? and symbols (as given by ?as.name?)." I think this that means recursive objects are: * lists * pairlists * calls * expressions Did I miss anything?

What do you prefer/recommend for double-banger function names: 1 scale.colour 2 scale_colour 3 scaleColour 1 is more R-like, but conflicts with S3. 2 is a modern version of number 1, but not many packages use it. Number 3 is more java-like. (I like number 2 best) Any suggestions? Thanks, Hadley

This is admittedly minor, and you shouldn't have repeated names in a data frame anyway, but: df <- data.frame(1:3, 1:3, 1:3) # Ok setNames(df, c("x", "y", "")) # Not ok setNames(df, c("x", "", "")) Hadley -- http://hadley.nz

Hi, Is there such a thing? If no: is it easily simulated? thanks, Joh

Hi all, Does anyone have an R implementation of the queplot (K.?M. Goldberg and B.?Iglewicz. Bivariate extensions of the boxplot. Technometrics, 34(3):pp. 307?320, 1992)? I'm struggling with the estimation of the asymmetry parameters. Hadley -- Assistant Professor / Dobelman Family Junior Chair Department of Statistics / Rice University http://had.co.nz/

...c(10, 1, 1)), 2:4)) #> int [1:3, 1, 1] 2 3 4 subset_ROW(data.frame(x = 1:10, y = 10:1), 2:4) #> x y #> 2 2 9 #> 3 3 8 #> 4 4 7 It seems like there should be a way to do this that doesn't require generating a call with missing arguments, but I can't think of it. Thanks! Hadley -- http://hadley.nz

I have two questions about the CRAN machines that build binary packages for Mac. When a new version of a package is released, (A) Do the downstream dependencies get re-checked? (B) Do the downstream dependencies get re-built? I have heard (but do not know for sure) that the answer to (A) is no, the downstream dependencies do not get rechecked. >From publicly available information on the

Hi, It would be great if one of the experts could comment on the difference between Hadley's dotlength and ...length? The fact that someone bothered to implement a new primitive for that when there seems to be a very simple and straightforward R-only solution suggests that there might be some gotchas/pitfalls with the R-only solution.

...framework? I want to be able to do something like: dmodel <- density(~ a + b, data = mydata) predict(dmodel, newdata) This isn't how sm or KernSmooth or base density estimation works. Are there other packages that do density estimation? Or is there some reason that this is a bad idea. Hadley -- http://had.co.nz/
