similar to: NA in character vectors

While R-1.5.0 is still unfrozen, I'd like to lobby again for a "pos" argument in library(). It seems straightforward to implement -- just change this line: env <- attach(NULL, name=pkgname) to: env <- attach(NULL, pos, name=pkgname) The reason I want this, by the way, is to mimic the S-Plus synchronize() command. Essentially, my version of synchronize() simply detaches a

I've uploaded a package colSums_1.0.tar.gz to CRAN /src/contrib/Devel. It contains functions colSums, colMeans, colVars, colStdevs, rowSums, rowMeans, rowVars, and rowStdevs. These do simple, fast arithmetic on columns/rows of a matrix, or more generally across dimensions of an array, e.g. colSums(m) = apply(m, 2, sum) but faster. They should be compatible with the corresponding S-Plus

as.character.factor contains this line (where cx=levels(x)[x]): if ("NA" %in% levels(x)) cx[is.na(x)] <- "<NA>" Is it possible that this is no longer the desired behavior? These two results don't seem very consistent: > as.character(as.factor(c("AB", "CD", NA))) [1] "AB" "CD" NA > is.na(.Last.value)[3] [1] TRUE

A new package "g.data" is available on CRAN, to create and maintain databases that work more like the S-Plus model. Here's the official Description for g.data (v1.2): Create and maintain delayed-data packages (DDP's). Data stored in a DDP are available on demand, but do not take up memory until requested. You attach a DDP with g.data.attach(), then read from it and assign

R> order(1, na.last=NA) Error in apply(sapply(z, is.na), 1, any) : dim(X) must have a positive length This bug appears unrelated to PR#1906, and so the fix of 8/15 doesn't help. It comes from the line inside order(): ok <- !apply(sapply(z, is.na), 1, any) where z=list(1) in my example. sapply() returns a single-element vector, not a matrix, making apply() unhappy. This might

Hello, R-devel! I posted to R-help, and (inappropriately) to R-bugs, this R/S-Plus difference: > LETTERS[c(NA,2)] in S is c("","B"), but in R is c("NA","B") Kurt Hornik <Kurt.Hornik@ci.tuwien.ac.at> wrote: > I think we do not want to change this. ... > R> is.na(LETTERS[c(NA,2)]) [1] TRUE FALSE > so we really have NA but it is

Hi all, I just noticed this odd behavior in R 1.5.1 (on Solaris 2.6): R> cut(c(2,NA), 1:5, labels=F) [1] 1 0 Is it a bug? I would have expected "1 NA" (better for indexing), and also the S-Plus analog is: S-Plus> as.integer(cut(c(2,NA), 1:5)) [1] 1 NA Apologies ahead of time if it's already fixed in R 1.6.0 and/or already known (perhaps related to

I'm picking up this 5-year old thread. 1. About the four memory allocations without a stacktrace I think the four memory allocations without a stacktrace reported by Rprofmem(): > Rprofmem(); x <- raw(2000); Rprofmem("") > cat(readLines("Rprofmem.out", n=5, warn=FALSE), sep="\n") 192 :360 :360 :1064 :2040 :"raw" are due to some

An NA in the rownames of a matrix (or dataframe) causes misalignment when the matrix is printed: R> x <- matrix(1:12, 3,4, dimnames=list(letters[1:3], LETTERS[1:4])) R> rownames(x)[2] <- NA R> x A B C D a 1 4 7 10 <NA> 2 5 8 11 c 3 6 9 12 The bug is in function Rstrlen, in src/main/printutils.c. MatrixRowLabel and MatrixColumnLabel (same file) rely on Rstrlen

Hey all, new R user and first timer here. I've been using getGraphicsEvent() on an X11-Xlib device in a kind of interactive loop, and would like to be able to stop it from printing newlines in the console when I don't actually want to print a prompt. Even an empty "" value still causes a newline right now. To not break any code that depends on this behavior, I figured getting

I have a daily job that attaches hundreds of pseudo-packages containing data as promise objects (DDP's, ref: g.data package), and plots the results to a multi-page pdf device. Sometimes it fails. Under R-2.2.1 it just gave segfaults. Under R-2.3.1 it gave this error message: *** caught segfault *** address (nil), cause 'memory not mapped' Traceback: 1:

(earlier I sent it as html by mistake). Hi, How can I get from C an object name used as a function argument? I have sample code in C that gives me access to the name of the function being called: SEXP xname(SEXP x) { const char *fun_name = CHAR(PRINTNAME(CAR(x))); x = CDR(x); const char *arg_name = isNull(TAG(x)) ? "" : CHAR(PRINTNAME(TAG(x)));

Hello, (This is follow up from this thread: http://www.nabble.com/execution-time-of-.packages-td22304833.html but with a different focus) I am often confused by the result of the profiler, when a loop is involved. Consider these two scripts: script1: Rprof( ) x <- numeric( ) for( i in 1:10000){ x <- c( x, rnorm(10) ) } Rprof( NULL ) print( summaryRprof( ) ) script2:

Channel map type tells us what the primary interpretation of the stored signals is. Channel definitions are there to tell which stored channel corresponds to which abstract channel in the type. Channel conversions define downmixes to secondary formats, as they do in MLP,

Hi, is there any way, based on userdb/passwdb attribute, how to postpone an email delivery? The purpose is, I need to freeze an account (Maildir++) for a few minutes and new email must not be delivered. But emails must be delivered when account is unfrozen. I found few things about Postfix filters, but I'm not sure it's a good way. Thank you, Milo

Thanks to David Meyer [david.meyer@ci.tuwien.ac.at] and David Brahm [brahm@alum.mit.edu] who suggested: m[ cbind(index.i, index.j) ] <- vals This works fine for the example I gave. Unfortunately, this approach doesn't extend to using the row and column names to make assignments: > m <- matrix("",ncol=3,nrow=3) > dimnames(m) <-

Hi, I am trying to write an LLVM project, using LLVM 2.9. My passes are defined as follows, where the Pass2 requires Pass1. namespace llvm { class BaseClass : public ModulePass { // Name for printing const char* printname; protected: BaseClass(char id, const char* name) : ModulePass(id),printname(name){ } }; class Pass1 : public BaseClass { public: static char ID; Pass1() :
