class(o)[!inherits(o,"AsIs")] is still in function 'get_all_vars' in R patched (in https://svn.r-project.org/R/branches/R-3-6-branch/src/library/stats/R/models.R). It was ported to R patched by r77402. On Monday, 18 November 2019, 8:12:10 PM GMT+7, Martin Maechler <maechler at stat.math.ethz.ch> wrote: >>>>> Martin Maechler >>>>>? ?

Hi, According to the help file for model.frame/get_all_vars, the following should produce the same output from both functions, but it doesn't... > dat <- list(X=matrix(1:15,5,3),z=26:30) > model.frame(~z+X,dat) z X.1 X.2 X.3 1 26 1 6 11 2 27 2 7 12 3 28 3 8 13 4 29 4 9 14 5 30 5 10 15 > get_all_vars(~z+X,dat) [1] z X <NA> <NA> <0

Hi everyone, This is about documentation for the model.frame() page. The get_all_vars() function (added in R 2.5.0) is a great addition, but the behavior of its '...' argument is different from that of model.frame() with which it is documented and this creates ambiguity. The current docs read: \item{\dots}{further arguments such as \code{data}, \code{na.action}, \code{subset}. Any

Dear R-devel, AsIs class seems to be well handled by `typeof` and `mode` function. Those two functions are being referred when explaining `is.vector` behaviour in manual. Yet `is.vector` does not seem to be handling AsIs class the same way. is.vector(1L) #[1] TRUE is.vector(I(1L)) #[1] FALSE Is there any reason behind this behaviour? Could we have it supported so AsIs class is ignored when

This seemed too advanced for r-help and is related to the recent discussion of character vectors in dataframes. Following Brian Ripley's most excellent advice, we are moving to a world in which character vectors in dataframes are always of class AsIs. The cool way of doing this seemed to be the following: > cat(c("x", "y", "z"), file = "test.txt",

Thank you Gabriel, Agree, although I think that could be relaxed in this single case and AsIs class could be ignored.

Here's an example (session info at the end). > tmpv <- c('\265g/L','Bq/L') > order(tmpv) [1] 2 1 > tmpv <- I(tmpv) > order(tmpv) Error in if (xi > xj) 1L else -1L : missing value where TRUE/FALSE needed > foov <- gsub('\265','',tmpv) > order(foov) [1] 2 1 > str(tmpv) Class 'AsIs' chr [1:2] "\265g/L"

Short example: > str(d <- data.frame(a = I(letters[1:5]))) `data.frame': 5 obs. of 1 variable: $ a:Class 'AsIs' chr [1:5] "a" "b" "c" "d" ... > str(d[TRUE,,drop = FALSE]) `data.frame': 5 obs. of 1 variable: $ a: chr "a" "b" "c" "d" ... The real problem about this is, that as soon

Greetings, I have been having a problem installing RQDA on my Mac (OS 10.13.2). I followed the installation process on the RQDA page ( http://rqda.r-forge.r-project.org/), but I keep getting an error message saying that I am missing pkg-config and GTK. I reinstalled XQuartz and GTK+ 2.24.17 multiple times (and reinstalled R version 3.4.4), but kept receiving the same error message. I also tried

Hello again, It appears that get_all_vars() incorrectly handles model formulae that use a right-hand side (rhs) matrix. For example, consider these two substantively identical models: # model using named variables mpg <- mtcars$mpg wt <- mtcars$wt hp <- mtcars$hp m1 <- lm(mpg ~ wt + hp) # model using matrix y <- mtcars$mpg x <- cbind(mtcars$wt, mtcars$hp) m2 <- lm(y ~ x)

Logic.Rd has been changed again in r74377. After change: ? \item{x, y}{raw or logical or \sQuote{number-like} vectors (i.e., of ? ? types \code{\link{double}} (class \code{\link{numeric}}, ? ? \code{\link{integer}}) and \code{\link{complex}}), or objects for It is still inappropriate. As I said before, integer is not double. Right: numeric includes double and integer Wrong: double includes

Hi R users, I want to build R-2.8.1 on AIX5.3, but I got following error message: Error in dyn.load(file, DLLpath = DLLpath, ...) : unable to load shared library '/rnd/homes/jixu/tmp/R-2.8.1/library/stats/libs/stats.so': rtld: 0712-001 Symbol d1mach was referenced from module /rnd/homes/jixu/tmp/R-2.8.1/library/stats/libs/stats.so(), but a runtime definition of

In R devel r71157, 'droplevels' documentation, in "Arguments" section, says this about argument 'exclude'. passed to factor(); factor levels which should be excluded from the result even if present. Note that this was implicitly NA in R <= 3.3.1 which did drop NA levels even when present in x, contrary to the documentation. The current default is compatible with x[ ,

In R devel r71124, if 'x' is a factor, droplevels(x) gives factor(x, exclude = NULL) . In R 3.3.1, it gives factor(x) . If a factor 'x' has NA and levels of 'x' doesn't contain NA, factor(x) gives the expected result for droplevels(x) , but factor(x, exclude = NULL) doesn't. As I said in https://stat.ethz.ch/pipermail/r-devel/2016-May/072796.html , factor(x,

Dear Experts, Could someone enlighten me about the following file: /etc/subuid ? This file appears to be owned by "setup" package. This is CentOS 7 system, and until now these files if existed were never changed. Today I have added user quite routine way, by doing /usr/sbin/groupadd -g 4500 [username] /usr/sbin/useradd -g [username] -u 4500 -c "User Name, email at domain"

I am basically fine with the change. How about using just the following? if(!is.character(exclude)) exclude <- as.vector(exclude, typeof(x)) # may result in NA x <- as.character(x) It looks simpler and is, more or less, equivalent. In factor.Rd, in description of argument 'exclude', "(when \code{x} is a \code{factor} already)" can be removed. A larger

There is no documentation for class AsIs, that is ?AsIs gives you nothing. Relatedly, there is no discussion of the use of I() to create objects of class AsIs on the help page for I(). This means that it is hard to find information in the help pages about the following usage. > test <- data.frame(x = I(letters[1:3])) > test x 1 a 2 b 3 c > class(test$x) [1] "AsIs"

(I think this is probably appropriate for r-devel -- if my diagnosis is correct, that is) I have a script that I run infrequently (i.e., quarterly) that has been working for several years. I re-ran it this morning for the first time since updating R from 2.6.2 to 2.7.0, and encountered an error. I found a simple example that shows the problem: > as.POSIXct( I( '2008-01-01' ) )
