Actually in R, we can do thinks like, the most naturally way in this the world: > "a" < "b" [1] TRUE >

Full_Name: Fan Version: 2.2.1 OS: Windows Submission from: (NULL) (159.50.101.9) Hello, When I call trellis function (such as histogram, densityplot, etc.) in a function, the call seems being ignored (no graphics is drawing) if some other instructions are placed afeter that call. Here's an example: y = rnorm(100*3) b = sample(1:3,300,replace=T) f = function() { densityplot(~y|b) }

The Design library has been fully ported to R except for Cox proportional hazards regression modeling (using Therneau's survival package) which will be available in about two weeks. It will take much longer to make all the example code executable, is it currently contains many examples for which data are not provided. Thanks to Xiao Gang Fan <xiao.gang.fan1 at libertysurf.fr> who

I had this problem too. The documentation for the winMenus says that these functions are part of the utils package. R must be loading this library after it sources in Rprofile. If you add library(utils) to the beginning of your .First function, it should take care of the problem. Brian Gregor, P.E.

Hi, I've read in the past a thead in the R discussion list about the multi-valued type variable (what was called checklist). At the moment Gregory had intention to add some general code in his gregmisc package. I'm wondering if there's some general code / packages available ? A general class for taking account this type of variable would be very useful in the domain of survey

I have uploaded to CRAN a new package named 'its' (Irregular Time-Series). It implements irregular time-series as an S4 class, extending the matrix class, and records the time-stamp of each row in the matrix using POSIX. Print, plot, extraction, append, and related functionality are available. Feedback and suggestions are welcome. Giles Heywood

Hi All, As a part of our regular data analysis, I have to read in large data sets with six columns and about a million rows. In Splus, this usually take a couple of minutes. I just tried R, it seems take forever to use read.table() to read in the data frame! It did not help much even though I specified colClasses and nrows in read.table(). How is R's ability to analyze large data sets? I

Hi all, I'm having difficulty converting a 'dates' object to a POSIXct object: testDATES<-c(35947,35971,36004,36008,36053,36066) testDATES<-chron(dates=testDATES, format = c(dates = "m/d/y"), origin=c(month = 12, day = 30, year = 1899)) >[1] 06/01/98 06/25/98 07/28/98 08/01/98 09/15/98 09/28/98 > as.POSIXct(testDATES) [1] NA NA NA NA NA NA

After wasting one whole day, I've finally decided to stay with 1.9.1, some problems have been reported to R-Bugs. For occasional users, I would say, there's no worst thing than that: you installed the new release, and soem of your existing codes no longer work ! -- Fan

There is something wrong, I think, with the date-time conversion from a numeric value if you use Central European Time (CET) as timezone. Examples from R: If I use the GMT time zone it is OK, I get the same time back from as.POSIXct as I entered > as.POSIXct(as.numeric(strptime("30/01/2012 13:00:00", format="%d/%m/%Y >

Dear all, I don't know the historical reason why the char '_' was defined in the R language grammar as a synonyme of the assignment <-, anyway the R documentation dosen't recommand its usage. Well, this is a real "incompatibility issue" each time we need to interface R with other language/systems, notably with database systems. Recall that, in perhaps all

Hello there fellow R-users, I have received some data which comes in the following format: example1<-"200301" The first 4 digits correspond to the year and the remaining 2 digits correspond to the week of the year. I have tried to convert this to a date by using strptime as follows: strptime(example1,format="%Y%U") where U (looking up strptime) is the week of the
