...r idea might be to use purrr:map instead, which is quite happy with X in your function: > xxx <- purrr::map(y,function(x,X){cos(x*X)},X=2*pi) > xxx [[1]] [1] 0.08419541 [[2]] [1] 0.6346404 [[3]] [1] 0.9800506 [[4]] [1] 0.8686734 [[5]] [1] -0.9220073 But don't feed `.x` to your purrrring cats, or fails silently: > xxx <- purrr::map(y,function(x,.x){cos(x*.x)},.x=2*pi) > xxx [[1]] NULL But who would have a function with `.x` as an argument? > ______________________________________________ > R-devel at r-project.org mailing list > https://stat.ethz.ch/mailman...

Hi All, I try to do a scatterplot for a bunch of variables. I plot a dependent variable against a bunch of independent variables: -- cut -- graphics::plot( v01_r01 ~ v08_01_up11, data = dataset, xlab = "Dependent", ylab = "Independent #1" ) -- cut -- It is tedious to repeat the statement for all independent variables. Found an alternative, i.e. : -- cut -- mu

Indeed. It struck me that a possible workaround would be to change the name of the first argum...

Would you care to share how your package installs its own dependencies? I assume this is done during the call to `main()`? (Last time I checked, R CMD INSTALL would not install a package's dependencies...)

Hello all, Everything was working very well. Now when I try to load lmerTest using: library("lmerTest"), I get this error: Error: package or namespace load failed for ?lmerTest? in loadNamespace(j <- i[[1L]], c(lib.loc, .libPaths()), versionCheck = vI[[j]]): there is no package called ?purrr? Nothing I've done has worked. I have uninstalled both R and R studio. I've

Thanks for the feedback Jeff.

I'd like to be able to prevent the <<- assignment operator ("super assignment") from assigning to the global environment unless the variable already exists and is not locked. If it does not exist or is locked, I'd like an error to be produced. This would allow me to evaluate expressions with this temporarily set to protect against mistakes. For example, I'd like to

I'm sure this exists elsewhere, but, as a trade-off, could you achieve what you want with a separate helper function F(expr) that constructs the function you want to pass to [lsv]apply()? Something that would allow you to write: sapply(split(mtcars, mtcars$cyl), F(summary(lm(mpg ~ wt,.))$r.squared)) Such an F() function would apply elsewhere too. /Henrik On Thu, Apr 16, 2020 at 9:30 AM

Why should it make an exception for cases where the about-to-be-assigned-to name is present in the global environment? I think it should warn or give an error if the altered variable is in any environment on the search list. -Bill On Sun, Mar 19, 2023 at 10:54?AM Duncan Murdoch <murdoch.duncan at gmail.com> wrote: > I think that should be the default behaviour.

I think that should be the default behaviour. It's pretty late to get that into R 4.3.0, but I think your proposal (with check.superassignment = FALSE being the default) could make it in, and 4.4.0 could change the default to TRUE.

Buenas Os queria preguntar que ventaja le veis a las tibbles frente a los data.table, ya que para mi, quitando el uso de librerias como tidyr o purrr, en el resto prefiero usar data.table. Me parece igual de potente y mucho más rápido, y no le veo las supuestas ventajas, pero quiero conocer vuestra opinion. Gracias Jesús [[alternative HTML version deleted]]

Estimados compañeros me gustaría saber si alguno ha utilizado la función add_model del paquete modeval cuando la variable de clasificación (y) tiene más de dos niveles. Porque si la utilizo con más niveles siempre me sale el error: Error: length(levels(factor((purrr::as_vector(y))))) == 2 is not TRUE Me parece muy interesante el paquete y no veo donde indica esta limitación. Un cordial

I'm running Ubuntu 17.04 and R 3.4.1. I installed the latter yesterday, so I presume it's the latest version. I want to install Tidyverse, which I've spent many happy hours with under Windows. But when I do install.packages("tidyverse") , I get errors about unrecognized command line options to gcc. These start when the install hits the colorspace and munsell packages.

Hola a todos, Escribo debido a una duda en la aplicacion de la funcion seq en cada uno de los "n" componentes de un vector "x". Hasta donde yo se, dicha funcion no permite el uso de vectores. En consecuencia, y como primera aproximacion a lo que deseo hacer, he construido un bucle  que retorne una lista de "n" vectores (de distinta longitud), donde cada uno de estos

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

Dear R Developers, After having fully read "Advanced R First Edition" , and having just bought my physical copy of "Advanced R Second Edition", I recommend that: Any community member interested in the development of R reads "Advanced R Second Edition", which explains R Language Core concepts cristal clear, and shows the motivation behind libraries such as

Dear R-devel, I periodically stumble on the same challenges when working with objects with bracket S3 methods, and their length and names counterparts. I make the distinction between what I call S3 subsetting using `[` and `[[` and low level subsetting using `.subset()` and `.subset2()`. When working with low level subsetting one has to be extremely careful, because `length()`, `names()`, and
