Dear R help list, I have a plot with two different vertical scales that I want to display on either side of the plot. It's quite similar to the Fahrenheit-Centigrade example in the examples section of the documentation for axis.default. The right-side axis is clipped off, though, and I haven't been able to figure out anything with viewport() and clipping or trellis.par.set to fix

Esteemed R Users, Would some one be patient enough to explain the variation i see when creating .pdf file output for my plots? FYI- my goal is produce the highest quality .pdf output from the R 'command line' as opposed to using the menu of the acitve graphics window. Im using 32bit WinXP. Session info at the bottom. I have Ghostscript v8.71 installed and in the Path such that

Full_Name: Sylvain Broh?e Version: 2.2.1 OS: Suse Linux 9.2 Submission from: (NULL) (164.15.109.58) I recently went to a new version of R (2.2.1) but now, when trying to save a plot in the png format, I got this error message : > png("my_plot.png") Error in X11(paste("png::", filename, sep = ""), width, height, pointsize, : unable to start device PNG

I want to do the following: DEVw=500 DEVh=350 fname="my_plot" dev.print(file=fname, device=FOO, width=DEVw, height=DEVh, bg="transparent") How do I do this such that I can specify FOO to be one of several choices? (GDD, PNG, postscript, etc.) If I make FOO a character variable, then "dev.print" complains. I tried a simpled "substitute" but

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? But: ls

Hi all, I can't figure out how to make this problem easily reproducible, but I can demonstrate it very simply, so I hoped someone might be able to suggest a place to start: > f <- function(x) substitute(x) > f(x) x > f(mpg) mpg attr(,"id") [1] 11 It works as expected in a clean R session: > f <- function(x) substitute(x) > f(x) x > f(mpg) mpg but not

For example, prepare like this > df.0 <- data.frame(x = 0, y = 0, note = "1") > df.1 <- subset(df.0, note == "1") > df.2 <- subset(df.0, note == "2") Then a call to > ggplot() + aes(x = x, y = y) + > geom_point(data = df.1) + geom_point(data = df.2) produces the error > Error in eval(expr, envir, enclos) : object 'x' not found

Hi all, I'm struggling with accessing a package dataset (munsell.map, stored in sysdata.rda) when that package is imported, not required. A simple reproducible example is: install.packages("munsell") munsell::mnsl("10B 4/6") # Error in match(col, munsell.map$name) : object 'munsell.map' not found library(munsell) munsell::mnsl("10B 4/6") # Function

Hi all, Does anyone have a comprehensive list of recursive-type objects 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? Hadley -- Assistant

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, Does anyone have any suggestions for debugging the execution of examples by R CMD check? The examples work fine when I run them from a live R prompt, but I get errors when they are run by R CMD check.

Hi all, What's the equivalent to length(unique(x)) == 1 if want to ignore small floating point differences? Should I look at diff(range(x)) or sd(x) or something else? What cut off should I use? If it helps to be explicit, I'm interested in detecting when a vector is constant for the purpose of visual display. In other words, if I rescale x to [0, 1] do I have enough precision to get

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.

readNEWS() states: Read R's ?NEWS? file or a similarly formatted one. This is an experimental feature, new in R 2.4.0 and may change in several ways and news() also indicates that this tool is supposed to work with non-R news files. However, I've not been able to get readNEWS to read a package news file, even when following the format indicated in news(). Looking at the

Hi there, is there a way to create a NAMESPACE file based on Rd-files (or whatever is needed in order to apply the regular expression "^[[:alpha:]]+" without(!) resorting to package.skeleton() (as this kind of interferes with roxygenize() pretty often)? Thanks a lot, Janko [[alternative HTML version deleted]]

Would this return a quosure? (i.e. a single sided formula that captures both expression and environment). That's the data structure we've adopted in tidyeval as it already has some built in support.

Hi all, If a package suggests another package in its description, you can check it at runtime with requires. How do you do check if a package is available without loading it, if you only want to access one function in the package namespace.

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/

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

Hi all, Since roxygen is a great help to document R packages, I am wondering if there exists an approach to go back from the raw Rd files to roxygen-documentation? E.g. turn "\author{Somebody}" into "@author Somebody". This sounds ridiculous, but I believe it helps in the long term for me to maintain R packages. Thanks! Regards, Yihui -- Yihui Xie <xieyihui at
