similar to: couldn't find function "print.tframe"

Hi Consider the following example: f <- function(expr) g(expr) g <- function(expr) { ? h(expr) } h <- function(expr) { ? expr # evaluation happens here ? i(expr) } i <- function(expr) { ? expr # already evaluated, no costs here ? invisible() } rprof <- tempfile() Rprof(rprof) f(replicate(1e2, sample.int(1e4))) Rprof(NULL) cat(readLines(rprof), sep = "\n") #>

"[<-" in R 0.63 does not appear to strip attributes, whereas Splus and previous versions of R did. Paul _____ R 0.63: > data <- matrix(rnorm(300),100,3) > attr(data, "tframe") <- c(1981.50, 2006.25 , 4.00) > attributes(data) $dim [1] 100 3 $tframe [1] 1981.50 2006.25 4.00 > z <- data[10:90,] > attributes(z) $dim [1] 81 3 $tframe [1]

I'm having some trouble figuring out latest.start in the tframe package. The results seem a bit cloudy. Sample session: > library(ts) > library(tframe) Loading required package: syskern > t1<-ts(c(1,2,3,4,5),start=1) > t2<-ts(c(1,2,3,4,5),start=2) > earliest.start(tbind(t1,t2)) [1] 1 1 > earliest.start(tbind(t2,t1)) [1] 1 1 > latest.start(tbind(t2,t1)) [1] 1 1

While commenting out the previously mentioned warning seems to work, I have been reflecting on this problem and there seems to be an issue wrt inheritance that I do not understand properly. Perhaps some gurus could comment. As mentioned previously, I have a class "tframe" with more specific classes indicating how time is being represented, such as > class(tframe(data)) [1]

I'm a day-old R newbie (but a war-weary S veteran), with couple of first-day questions: In R 0.61, this code fails. Ops.test <- function(e1,e2) { e1 <- NextMethod(.Generic) e1 } x <- 4 class(x) <- "test" y <- x < 3 The error message is "Error in NextMethod(.Generic) : negative length vectors are not allowed.". I assume it is a bug.

I am having problems with the package dse. I just installed R 2.2.1 and reinstalled all packages. I am running Windows XP Pro with all updates. Below there are two examples of error messages generated when trying to execute some simple programs. The code was taken directly from the package documentation. Any help on this will be greatly appreciated. Merry Christmas Fernando

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:

I ran into an interesting issue with `evalq` (and also `eval(quote(...))`): ???? f <- function() { ?????? list( ???????? sys.parent(1), ???????? evalq(sys.parent(1)), ???????? evalq((function() sys.parent(2))()),? # add an anon fun layer ???????? evalq((function() sys.parent(1))()) ?????? ) ???? } ???? res <- f() ???? str(res) ???? ## List of 4 ???? ##? $ : int 0???????? # sys.parent(1)

Hi, I have written boxplot commands of this form before, but I don''t quite understand why the function call is reporting a syntax error in this instance. All parameters passed to the function are strings. Thanks in advance. Payam > simplevar <- function(wframe,column1,column2) { + tframe <- get(wframe) + x1 <- which(names(wframe)==column1) + x2 <-

My question is when the object argument of NexthMethod be used? In the following example, weather object argument is used will not affects the result. ### foo=function(x) {UseMethod("foo")} foo.cls1=function(x) { x=x+1;class(x)<-"ncls" NextMethod() } foo.ncls=function(x) { cat("ncls\n") } foo.cls2=function(x) { cat("cls2\n");print(x) }

Below are a few problems I have encountered with the new checks being done in R-devel. 1/ I have two generics, test.equal and test.equal.tframe. The first checks that two objects are equal while the second checks if two objects have equal tframes (time frames). There is no reason these should have similar arguments but the check seems to think that test.equal.tframe is a method for test.equal so

I have a class "tframe" with more specific classes indicating how time is being represented, such as > class(tframe(data)) [1] "ts" "tframe" but now "[.ts" produces warning messages > tframe(data)[2] Warning: Not returning a time series object [1] 2006.25 Even my simplest tests produce hundreds of lines of warnings, so I've commented out

I am having some difficulties using dynamically loaded C functions on a Sparc 10 with R compiled using cc (both R-0.49 and R-0.50). I get sporadic errors with the error message: Error: character variables must be duplicated in .C/.Fortran, with C functions which pass character variables. my C functions look like: anyfunc(char **filename, other variables ) This error message appears about 25%

I was debugging a problem reported to me regarding PL/R, and found that I can duplicate it using only R sources. It might be characterized as possibly a misuse of the findFun() function, but I leave that for the R devel experts to decide. The below results are all with R-2.5.1 (I can't seem to download r-patched at the moment, but didn't see anything in the 2.5.1-patched release

After long but intermittent discussion (it was mentioned at DSC99, for example), we have reorganized the standard packages, with base graphics stats utils methods normally loaded, mle splines stepfun tcltk tools available for loading, and ctest eda lqs modreg mva nls ts as stub packages which ensure back-compatibility. (These have all been merged into stats except lqs which rejoins

Hi I am using the flowClust package from BioConductor, which is largely implemented in c. For some of my data, the package occasionally (and quite stochastically) encounters a particular condition which halts its operation. At this point, it calls the error() function defined by Rcpp, and halts. What I would like to be able to do is to catch the error thrown, and retry the operation a few
