Hosking Version: 1.9.0 OS: Windows 2000 Submission from: (NULL) (129.34.20.23) Browsing the code of as.data.frame.list, I see cn[m] <- paste("..adfl.", cn[m], sep = "") and 5 lines later names(x) <- sub("^..adfl.", "", names(x)) It looks as though the latter should be names(x) <- sub("^\\.\\.adfl\\.",

Hello, I have upgraded from Mandrake Linux 8.0 to Mandrake 8.1 and try to reinstall my favourite R... Everything is OK for the base software but I have trouble to get some packages installed. Specifically, for some packages, a "collect2" binary seems to be necessary during the compilation/linking process of the library, and LD complains about not finding it : Installing source

Hello, I want to maximize a likelihood function expressed as an integral that can not be symbolically evaluated. I expose my problem in a reduced form. g<- function(x){ integrand<-function(y) {exp(-x^2)*y} g<-integrate(integrand,0,1) } h<-function(x) log((g(x))) g is an object of the class function, but g(2) is a integrate object, I can print(g(2))

Is this a bug? > f1 <- factor(c("a", NA), levels = c("a", "NA") ) > f2 <- f1[, drop = TRUE] > f2 [1] a <NA> Levels: a <NA> I would have expected f2 to have only one level, "a". It seems to me that the code in [.factor does not follow the advice in help("factor") on how to set factor codes to be

Full_Name: J. R. M. Hosking Version: 1.3.0 OS: Windows 2000 Submission from: (NULL) (198.81.209.16) R documentation suggests that if a function argument x is omitted, missing(x) should return TRUE even if x is subsequently assigned a value. This happens in S-plus. But in R: > test function(x){ print(missing(x)) if(missing(x)) x<-0 print(missing(x)) invisible() } > test() [1] TRUE [1]

It seems that when an argument 'mgp' is supplied to axis(), the mgp[2] value (position of tick mark labels) is honoured but the mgp[3] value (position of axis line) is ignored. Example: plot(1:5, xaxt='n', ann=FALSE) par(mgp=c(0,2,1)) axis(1, at=2:4, mgp=c(0,-2,-3)) Axis line is plotted at margin line 1, tick mark labels at line -3. Is this a bug? J. R. M. Hosking

Dear Sir in the following example,is the vector lmom a l-moment ratios vector? What is meant by size = northCascades[,1]? And what are the values in c(0.0104,0.0399,0.0405)? Please help me I am unable to understand these from help manual. Best Regards AMINA data(northCascades) lmom <- c(1, 0.1103, 0.0279, 0.1366) kappaParam <- kappalmom(lmom) heterogeneity(500, 19, size =

Dear R forum I have a data.frame as cashflow_df = data.frame(instrument = c("ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC","ABC", "ABC", "PQR", "PQR",

Hi, I want to construct a data.frame 'y' by using x$x and x$y. I think that there might be better ways to do it (because, for example, we can use a_matrix[3:5,] to extract certain rows, where 'a_matrix' is a matrix). Can somebody let know what the best way is? > a=data.frame(x=1:10,y=rep("abc",10),z=rep("xyz",10)) > a x y z 1 1 abc xyz 2 2

Hi everyone, In the package POT, there is a function that computes the L-moments of a given sample (samlmu). However, to compute those L-moments, one needs to obtain the total number of combinations between two numbers, which, by the way, requires the use of a factorial. See, for example, Hosking (1990 , p. 113). How does the function "samlmu" in the package POT avoids overflows? I

With 0.64.1 on Intel RH5.2, abc <- list() abc$abc$abc <- matrix(1:20) mt <- terms(~(abc$abc$abc[,1]==64)|(abc$abc$abc[,1]==65)|(abc$abc$abc[,1]==75) |(abc$abc$abc[,1]==84)|(abc$abc$abc[,1]==85)) model.matrix(mt,model.frame(mt)) crashes. With ab$ab$ab, it does not. Apparently, the bug I reported for 0.64.0 has just been pushed back one step. Jim

Hi, I was playing around with inotifywait (great tool!) to see the new staged installation of source packages in action. In one terminal I'm monitoring the create/delete/move events of the installation library with: ? inotifywait -m --timefmt '%F %T' --format '%T -- %w %e %f' -e create -e delete -e move path/to/R/library/ While in another terminal I install CRAN package

Hi, I have a setup problem with Shorewall 4.0.6, which I can''t figure out why it is not working: I want to install a fireall with 2 extra interfaces : - My serv ("dmz") zone is a /28 subnet behind eth1, with a small number of SUN servers (IPs between ABC.DEF.75.1 and .13), one of which is a DHCP server for the 75 subnet. - The loc zone are PCs in the 75 subnet behind eth2

Here is a possible BUG with as.data.frame() and/or [.data.frame which broke Michael Lapsleys RODBC-Code. Can anyone confirm it is a bug or a 'feature' of the prototype? tablename <- "abc" a <- as.data.frame(cbind("abc", 1:3)) b <- as.data.frame(cbind(tablename, 1:3)) # ok > a V1 V2 1 abc 1 2 abc 2 3 abc 3 # missing column name > b tablename 1
