Dear Ashim, I?ll address your questions briefly but they?re really not appropriate for this list, which is for questions about using R, not general statistical questions. (1) The relevant distribution is within cells of the wool x tension cross-classification because it?s the deviations from the cell means that are supposed to be normally distributed with equal variance. In the warpbreaks data

Akhilesh, I don't know if I am adding signal or noise here, but I installed R 3.5.0 yesterday and installed data.table just fine, but I have Rtools installed. "Building packages from source" may sound intimidating, but Rtools is really easy to install and once installed, it does all the work for you.

Dear Akhilesh, I hope that it's clear that the Windows binary I provided for the data.table package is a temporary solution, and that the maintainer should fix the package so that it passes its own tests. You should be careful using the package in its current state. Best, John > -----Original Message----- > From: Akhilesh Singh [mailto:akhileshsingh.igkv at gmail.com] > Sent:

Dear Sir, Many thanks for your reply. I have a query. I have a whole set of distributions which should be made normal / homoscedastic. Take for instance the warpbreaks data set. We have the following boxplots for the warpbreaks dataset: a. boxplot(breaks ~ wool) b. boxplot(breaks ~ tension) c. boxplot(breaks ~ interaction(wool,tension)) d. boxplot(breaks ~ wool @ each level of tension) e.

Dear Rodrigo, Try tkwm.geometry(win1, "-0+0"), which should position win1 at the top right.

Not happening on Mac, so likely a Windows build issue. (There's no 4.0.1 CRAN package yet, and no nightly build of 4.0.1 Patched, but the only thing changed in the sources since r78644 is the VERSION file.) -pd > On 7 Jun 2020, at 03:13 , Fox, John <jfox at mcmaster.ca> wrote: > > Hi, > > The following code, from the examples in ?TkWidgets , immediately crashes R

Dear A.K. Singh, As you discovered, the data.table package has an error under R 3.5.0 that prevents CRAN from distributing a Windows binary for the package. The reason that you weren't able to install the package from source is apparently that you haven't installed the R package-building tools for Windows. See <https://cran.r-project.org/bin/windows/Rtools/>. Because a number of

John, The Windows installation instructions document has the following. So, one obvious question is whether you did select it. (I haven't installed on WIndows for ages, so I don't know whether this was changed recently or even whether the selection is on or off by default). -pd Using package tcltk =================== The package tcltk supports building graphical interfaces with Tcl/Tk.

Dear Thomas, This looks like a really interesting project, and I don't think that anyone responded to your message, though I may be mistaken. I took at a look at implementing parallel assignment, and came up with: passign <- function(..., envir=parent.frame()){ exprs <- list(...) vars <- names(exprs) exprs <- lapply(exprs, FUN=eval, envir=envir) for (i in

Dear Faiz, Bootstrapping R^2 using Boot() is straightforward: Simply write a function that returns R^2, possibly in a vector with the regression coefficients, and use it as the f argument to Boot(). That will get you, e.g., bootstrapped confidence intervals for R^2. (Why you want that is another question.) See the example in ?Boot that shows how to bootstrap the estimated error variance (without

Always hard to tell if THIS is a homework project. As with most things in R, if you can not find at least a dozen ways to do it, it is not worth doing. The question (way below) was how to take two vectors of length two and make a longer results based on using the ":" operator to generate a range between the first element of each array and then between the second elements and return the

My thanks to Dr. John Fox and Dr. Duncan Murdoch. But, I have upgraded all my R-3.4.3 libraries to R-3.5.0, and I have not backed-up copies of old version.

If you're installing packages to the default location in your home account and you didn't remove those library folders, you still have you R 3.4 package installs there, e.g. > dir(dirname(.libPaths()[1]), full.names = TRUE) [1] "/home/hb/R/x86_64-pc-linux-gnu-library/3.4" [2] "/home/hb/R/x86_64-pc-linux-gnu-library/3.5" [3]

You are right. I do take backups. But, this time I was too sure that nothing will go wrong. But, this was over-confidence. I need to take more care in future. Thanks anyway. With regards, Dr. A.K.

Hmm, looks like that thread has more noise than signal... AFAICT, data.table currently fails selftests i 3.5.0 on all platforms on the CRAN builders, so RTools issues are only incidental and it would be better to fix data.table in the sources. From the looks of it, I wouldn't be surprised if the root cause is the changes to POSIXlt methods in 3.5.0, but I haven't actually been digging
