Dear all, Is there a quick and easy way of converting utf characters to the \uxxxx form (necessary e.g. for packages)? I mean something working like this: > utf2uxxxx("õäöü") [1] "\u00f5\u00e4\u00f6\u00fc" It is easy to program but perhaps someone already has implemented this. (I couldn't find anything useful from searches incl RSiteSearch). Thanks in advance, Kenn

Dear all, I've used RODBC a lot to read in files created in MS excel and access but found a strange problem today: a variable in my data file contained both numbers and text; sqlFetch would set text within a row of numbers to NA; but if first 5 or 6 rows would be text then all numbers would be read in as NA. con<-odbcConnectExcel("xample.xls") #the file is attached or at

Dear all, I hope this is a right place to post this; r-help might be appropriate but it looks like I'm suggesting a change in base package, so I decided to post here. (+ Apologies if that has been changed recently -- the version I'm using is R.2.12.2 on Windows.) I've noticed an unexpected behavior of trunc.POSIXt: foo <- seq(as.POSIXct( "2009-10-23 22:00:00"),

Dear all, I sometimes use the following function: Curry <- function(FUN,...) { # by Byron Ellis, https://stat.ethz.ch/pipermail/r-devel/2007-November/047318.html .orig <- list(...) function(...) do.call(FUN,c(.orig,list(...))) } ... and have thought it might be convenient to have a method for [ doing this. As a simple example, > apply(M, 1, mean[trim=0.1]) # hypothetical

Dear all, While buildign a package (R 2.15.2 on windows XP) I had three warnings/notes -- I would be grateful for any hints on what to do. 1. The first one is probably not really important if I'm not missing something: cygwin warning: MS-DOS style path detected: C:/x/y/z/package_1.0.tar.gz Preferred POSIX equivalent is: /cygdrive/c/x/y/z/package_1.0.tar.gz CYGWIN environment variable

There was a question in R forum very long time back.. on how to protect R Script files from inadvertent editing by users. There is a way to do this from within R, atleast in Windows XP I have tried this and it certainly works , The method is very different from the OS based folder protection route, however making available such a method in the open forum would only kill the very spirit of R.

Suppose X is a long vector of integers (typically about 30000 elements). Is there an efficient way to detect whether there are at least N consecutive zeros in X, and if yes, where does this occur? for example, suppose X is: 1 2 3 4 5 0 0 0 0 0 0 0 0 0 0 0 0 0 0 3 4 2 0 1 2 0 0 0 2 2 2 2 2 ... and N is 10. I would like a foo(X, 10) to return something like c(6,19) (start and end positions in X

Dear r-devel list members, On a couple of occasions I've encountered the issue illustrated by the following examples: --------- snip ----------- > mod.1 <- lm(Employed ~ GNP.deflator + GNP + Unemployed + + Armed.Forces + Population + Year, data=longley) > mod.2 <- update(mod.1, . ~ . - Year + Year) > all.equal(mod.1, mod.2) [1] TRUE > > f <-

Hallo! Is there a package in R that does Q-type factor analysis? I know how to do principal component analysis, but haven't found any application of Q-type factor analysis. Thx, Julia -- Psssst! Schon vom neuen GMX MultiMessenger geh?rt? Der kanns mit allen: http://www.gmx.net/de/go/multimessenger

Hi all, Does anyone have a comprehensive list of recursive-type objects in R? is.recursive defines them as by exclusion: "most types of objects are regarded as recursive, except for vector types, ?NULL? and symbols (as given by ?as.name?)." I think this that means recursive objects are: * lists * pairlists * calls * expressions Did I miss anything? Hadley -- Assistant

Dear R-users, Is there a way I can prevent global variables to be visible within my functions? Sebastien

Hello all I would like to ask your help use mapply. I have a function called findCell that takes two arguments(x,sr) where x is a vector of size two (e.g x<-c(2,3) and sr is a matrix. I would like to call many times the findCell function (thus I need mapply) for different x inputs but always for the same sr. as x is a vector of size two (two cells) I want to pass inside inside the following

Friends. I cannot simplify this much, and I think the loop is unavoidable. As a recovering C programmer I want to avoid loops and in cases like this I almost allways can by using an apply function. But I suspect in this case there is nothing I can do. It is a finance example where a price series is compared to a moving average. If the price goes above the average, plus a bit, buy the

Dear R, When I'm writing script I probably hit accidently some hot key and then the text in script is being overwritten by subsequent typing. Please what is the hot key or how can I disable it? -- View this message in context: http://r.789695.n4.nabble.com/random-typing-over-text-tp3470428p3470428.html Sent from the R help mailing list archive at Nabble.com.

Ok, Thanks foe the answer, Ken: *1L, 2L etc are integers. (That is, identical to as.integer(1) , as.integer(2) etc) Using integers (instead of "numeric" type) is more efficient as here they're used as indexes and would be converted to integer anyway. Compare > is(1) ... and > is(1L) 1L:p is the sequence 1, 2, 3, ..., p (just like 1:p) Just for curiosity, what is

Hello, I am trying to set up a Xen/Remus test configuration on AMD64 hardware (HP DL380 G6) under SuSE 10.1 and am having trouble. I was able to run and configure the Xen 3 that came with SuSE fine, but as far as I can see, I have to use Xen 4 to get Remus. I managed to build Xen 4 from source and it seemed to install, but I am not sure how to get the proper kernel and/or initrd files in place

Is it possible to use isolinux to create a bootable dvd? I have a .iso that boots fine from cd but not from dvd. I have a Dell OptiPlex GX240 with dvd/cd drive. Dont know for sure if the bios requires an update to boot dvd. Any info would be appreciated.

Hi Is it possible to subset an n-dimensional array by a vector of n dimensions? E.g. assume I have > x <- array(1:24, dim=2:4) > x[1,1,2] [1] 7 > dims <- c(1,1,2) I would like a function that I can supply x and dims as parameters to, and have it return 7. Also, I would like to do something like: > x[1,1,] [1] 1 7 13 19 > dims2<- c(1,1,NA) And have a function of x and

Hi, I'm trying to execute the same R code on multiple data frames listed in a single directory. The code works fine if I use the code (below) for each file. However, I have several files and it becomes tedious to run each one, name it and then aggregate into a single dataframe. Name 0.0           1 21.15       2 2400.26   1 3222.14   2 name = read.table(file.choose(),header=F) #
