Bugzilla issue 16101 describes another first-list-name-printed-differently oddity with the Windows GUI version of R: > a <- "One is \u043E\u0434\u0438\u043D\nTwo is \u0434\u0432\u0430\n" > Encoding(a) # expect "UTF-8" [1] "UTF-8" > sapply(strsplit(a, "\n")[[1]], charToRaw)[c(1,1,2)] $`One is ????` [1] 4f 6e 65 20 69 73 20 d0 be d0 b4 d0 [13] b8

Hi all Four questions regarding Unicode. Three Windows questions. I am using - a PC with Windows XP (Build 20600.xpsp080413-2111 (Service Pack 3); - the following R version: > R.version platform i386-pc-mingw32 arch i386 os mingw32 system i386, mingw32 status major 2 minor 7.0 year 2008 month 04 day 22 svn

Hi I'm having trouble sourcing or parsing a UTF-8 file that contains characters that are not representable in the current locale ("foreign characters") on Windows. The source() function stops with an error, the parse() function reencodes all foreign characters using the <U+xxxx> notation. I have added a reproducible example below the message. This seems well within the

Also why should that difference result in different behavior?

That's justifiable, I think; consider: > d1 = data.frame(a = 1:4) > d2 = d3 = data.frame(b = 1:2) > row.names(d3) = c("a", "b") > data.frame(d1, d2) a b 1 1 1 2 2 2 3 3 1 4 4 2 > data.frame(d1,

In that case identical should be FALSE but it is TRUE identical(a1, a2) ## [1] TRUE On Tue, Nov 14, 2023 at 8:58?AM Deepayan Sarkar <deepayan.sarkar at gmail.com> wrote: > > They differ in whether the row names are "automatic": > > > .row_names_info(a1) > [1] -3 > > .row_names_info(a2) > [1] 3 > > Best, > -Deepayan > > On Tue, 14 Nov

One would normally want the original order that so that one can stack a list, operate on the result and then unstack it back with the unstacked result having the same ordering as the original. LL <- list(z = 1:3, a = list()) # since we can't do s <- stack(LL,. drop = FALSE) do this instead: s <- transform(stack(LL), ind = factor(as.character(ind), levels = names(LL))) unstack(s)

Also note that the functionality discussed could be regarded as a generalization of matrix multiplication where * and + are general functions and in this case we have * replaced by == and + replaced by &.

I don't think it has much to do with transform in particular: > BOD <- data.frame(Time = 1:6, demand = runif(6)) > BOD[["X"]] <- BOD[1:2] * seq(6); BOD Time demand X.Time X.demand 1 1 0.8649628 1 0.8649628 2 2 0.5895380 4 1.1790761 3 3 0.6854635 9 2.0563906 4 4 0.4255801 16 1.7023206 5 5 0.5738793 25 2.8693967 6 6 0.9996713

Can you clarify what the nature of the security restriction is? If you can't run the R installer then how it is that you could run R? That would still involve running an external exe even if it came in a zip file. Could it be that the restriction is not on running exe files but on downloading them? If that is it then there are obvious workarounds (rename it not to have an exe externsion or

1. If your PATH is very long then on the Select Additional Tasks screen in the Rtools installer the two check box titles (Edit the system PATH and Save version number) will be obscured (i.e. you won't be able to see them at all) making the screen very confusing. One just sees two boxes on the left and a long path on the right and has no idea what it all means. Also even with a short path the

Couldn't R simply regard .First.lib as the appropriate function to save many packages from being needlessly changed?

It seems that R is mostly distributed with the tcltk package but not always. Is there some reason for this inconsistency? It would be nice if one could count on those packages that are distributed on the Windows version of R being distributed on all other platforms too. -- Statistics & Software Consulting GKX Group, GKX Associates Inc. tel: 1-877-GKX-GROUP email: ggrothendieck at gmail.com

I would like to be able to load two versions of a package at once and to do that was thinking of giving each version a different package name in the DESCRIPTION file and the building and installing each such version separately. library(myPkg1) library(myPkg2) and then use myPkg1::myFun() and myPkg2::myFun(). To do that easily it would be convenient if one could change the package name in only

In R devel rev.66393 (2014-08-15) it was possible to do this: trace(optim, exit = quote(str(returnValue()))) but returnValue() does not seem to be available any more. The above was useful to get the output of a function when it was called deep within another function that I have no control over. Has this been replaced by some other equivalent function? P.S. This demonstrates that it no

Regarding, this news item for r-devel: ?for()? loops are generalized to iterate over any object with ?[[? and ?length()? methods. Thanks to Herv? Pag?s for the idea and the patch. Below dd is an object for which [[ and length work but the result is still numeric rather than Date class in "R Under development (unstable) (2016-03-15 r70334)" as observed in the comments to:

This works: my.compose <- function(f, ...) { if (missing(f)) identity else function(x) f(my.compose(...)(x)) } my.compose(sin, cos, tan)(pi/4) ## [1] 0.5143953 sin(cos(tan(pi/4))) ## [1] 0.5143953 But replacing my.compose with Recall in the else causes it to fail: my.compose2 <- function(f, ...) { if (missing(f)) identity else function(x) f(Recall(...)(x))
