Dear listeRs, I'm finding that apply() behaves strangely when used on a 3-d array. For example: > at <- array(1:27,dim=c(3,3,3)) > at , , 1 [,1] [,2] [,3] [1,] 1 4 7 [2,] 2 5 8...

Hi R-core, I have been performance testing R packages for wide-to-tall data reshaping and for the most part I see they differ by constant factors. However in one test, which involves converting into multiple output columns, I...

Hi, Apologies up front if this has been covered somewhere already -- I have seen some discussion of a similar problem on the list, but it doesn't quite seem to cover what I'm after. Also I'm new to...

Hi Jie Tang, You could try my "Friendly Beginners' R Course". Online resource at: http://www.R-project.org/ ? Documentation/Other (left-hand panel) ? Contributed Documentation (middle of screen) ? (scroll down a little) which is a quick intro to what...

Also, the na.omit method for data.frame with list column seems to be inconsistent with is.na, > L <- list(NULL, NA, 0) > str(f <- data.frame(I(L))) 'data.frame': 3 obs. of 1 variable: $ L:List of 3...

Is there a way to add residuals to plots produced by plot.gam in the mgcv package? I'm looking for something like what you get using resid=T in Splus plot.gam. Thanks in advance Toby -----Original Message----- From...

Hi! I expected that t.test should report a very large p-value (close to 1), even when using paired=TRUE, for the data below (which are very similar). However, I observe p-value = 0.02503 which indicates a significant...

Hi Greg thanks for your interest! I plan to submit an application next week, on behalf of R project. Our wiki with a timeline is https://github.com/rstats-gsoc/gsoc2025/wiki#status-and-timeline If you would like to...

Dear R: I'm trying to map some time series data on to dates and because I'm using R's "strptime' facility I get an hour's break in my time series: my readings for between 1am and 2am...

Dear R help, In the middle of my session, I started receiving the error message "bad value" regardless of what I entered. I had to close R and restart it. When the error occurred, I was creating basic lattice plots...

Dear R-sig-gui, I'm using R 2.5.1 for Windows. Here's an interesting one (perhaps!): If I have the Console window about 80 characters wide, I can do the following commands: > > a=c("Jan","Feb","Mar...

Is the intent is to encourage the user to do something simpler like... aggregate(y ~ f, df1, mean)$y aggregate(y ~ f, df1, mean)["y"] aggregate(y ~ f, df1, mean)[["y"]] ?? On Sat, Jul 16, 2022 at 8:27 AM...

You could take some of your observations and turn them into patches that would help improve R. (discussion of such patches is one function of this email list) On Sun, Apr 10, 2022 at 9:05 AM Stephen H. Dawson...

On a related topic to this - can someone tell me how to independently alter the fontsize and position of text on a persp plot?? I've tried using titles() and axes() but they seem to only apply to the standard...

Dear R listers, If I try to start the X11 device in Gentoo, I get the following complaint from R: ------------------- > X11() Error in X11() : could not find any X11 fonts Check that the Font Path is correct. ------------------- xset -q produces...

Hi Maria, Instead of using errbar(), you can use the segments command which may be more flexible. Following the example on p.80 (the errbar command) of http://cran.ma.ic.ac.uk/web/packages/Hmisc/Hmisc.pdf set.seed...

Hi Ilya, If you're looking for general information about statistical tests, etc., you'll probably need to buy yourself a textbook. There are online pages (http://homes.msi.ucsb.edu/~byrnes/rtutorial.html is a good one), but a...

Hi, all! I'm trying to compile R on a Solaris machine. The default C compiler is cc (although gcc is available) and the default Fortran compiler is f95 (although g77 is available). Without defining the F77 environment variable, configure...

Hi Tomas thanks for the explanation. Does that mean that there is no known fix? i.e. it is OK to re-submit a new version of my package without fixing these WARNINGS? On Tue, Sep 24, 2019 at 1...

Hi Rcpp Devs, Does anyone know how to fix this warning in a package with LinkingTo: RcppArmadillo? My package plotHMM https://www.stats.ox.ac.uk/pub/bdr/LTO/plotHMM.out got this message on CRAN Additional Checks LTO flavor...
