Hello, All: What thoughts might you have on "The R Software Package Development Process"? I'm looking for ideas, materials, references, and / or collaborators for an article on this topic to be submitted to the Communications of the ACM. My limited experience with other languages such as Matlab and Python suggests that R may be fairly unique with CRAN and this

Hello All: I'm still unable to get Rprofile.site to set, e.g., options(max.print=222), as I did with previous versions of R. I just found similar questions posed by Trevor Miles and Ross Bowden with replies by Uwe Ligges and Duncan Murdoch. In addition to the things I tried documented below, I also copied Rprofile.site into "R_HOME/etc/i386" and

Hello: What is the recommended method for retaining the tzone attributes when concatonating POSIXct objects? > (d1 <- ISOdate(1970,1,1)) # Sets the tzone attribute = GMT [1] "1970-01-01 12:00:00 GMT" > (d1.2 <- c(d1, d1)) # c(..) strips the tzone attribute, displays in the time zone of the operating system [1] "1970-01-01 04:00:00 PST" "1970-01-01

I computed "system.time(diag(30000))" with R 2.12.0 on Fedora 13 Linux with 4 GB RAM and with R 2.14.1 on Windows 7 with 8 GB RAM: Linux (4 GB RAM): 0, 0.21, 0.21 -- a fifth of a second Windows 7 (8 GB RAM): 11.37 7.47 93.19 -- over 1.5 minutes. Moreover, during most of that time, I could not switch windows or get any response from the system. When I first encountered this, I

Hello, All: What can people tell me about converting back slashes to forward slashes in character strings? Several years ago, Prof. Ripley provided a solution, which I lost and have not been able to find. Below please find a function to do this. I do not find this very satisfactory, however, because it uses "scan" and therefore operates on an input not a

Hello: I get "Wide character in print" from trying read.xls("22_data.xls") in the gdata package, with "22_data.xls" downloaded from "Varieties_Country_A-E.xls" at "http://www.reinhartandrogoff.com/data/browse-by-topic/topics/7/": > library(gdata) > read.xls("22_data.xls") Wide character in print at

Hello, All: How can I obtain the location of an example data file in a package during "R CMD check"? I want to include sample raw data files in a package and have them read by a function in the package. It occurs to me to put such a file in "\inst\rawdata" and have examples find the data using something like "system.file('rawdata',

I just encountered another RTFM problem: With diff(as.POSIXct(...), ...) I was unable to control the units of the results. Examples: > (d.d <- diff(as.POSIXct(c('2012-12-12', '2012-12-13')))) Time difference of 1 days > (d.h <- diff(as.POSIXct(c('2012-12-12 08:00', '2012-12-12 09:00')))) Time difference of 1 hours > (d.m <-

Hello, All: The "writeFindFn2xls" function in the "sos" package tries to write an Excel file with 3 sheets ('PackageSum2', 'findFn', 'call'). Unfortunately, it is often unable to do this because of configuration problems that are not easy to fix. I've found 3 contributed packages that provide facilities to write Excel files with

Hello All, I recently upgraded one of my HP-UX servers from Samba 2.2.4 to 2.2.7. Since that time, I have noticed that disk activity on the file system where the Samba var directory is kept seems to be higher than I would expect. We have now begun to experience a problem with PC clients running National Instruments' LabView software, installed on a Samba share. When any PC client tries to

Sehr geehrte Damen und Herren, An der Fachhochschule Winterthur wurde f??r mich im Rahmen einer Diplomarbeit (Prof. Ruckstuhl) ein R-Programm zur Auswertung von IR-Spektren (line-shape-Analyse zur quantitativen Analyse von Gasmischungen) entwickelt. Die Daten werden einer Excel-Tabelle entnommen. Bisher werden die spektroskopischen Daten ??ber den Inhalt von 64 Kan??len ??ber die

Hello: I've been using "Rprofile.site" for several years to set the repos environment variable as follows: options(repos=c(CRAN='http://cran.cnr.berkeley.edu', CRANextra='http://www.stats.ox.ac.uk/pub/RWin') ) However, R 2.15.0 is not recognizing this. Instead, I get the following: options('repos') $repos

Hello, All: What references exist on how to link to C? I'm familiar with sections 5.2 and 5.6 of the "Writing R Extension" manual plus chapter 6 of Venables and Ripley (2000) S Programming (Springer). From these, I get the following: R storage mode C type logical int * integer int * double double * complex Rcomplex *

Hi, Paul: "if(!fda::CRAN())" runs code except with "R CMD check ?as-cran". I use it so CRAN checks skip examples that (a) need the Internet or (b) take too long for CRAN. Hope this helps.

Hello: I have so far failed to get Rprofile.site to be processed in R 2.15.0 under Windows 7 as I remember having done it in previous version of R. For example, I've included "options(max.print=222)" in "R_HOME/etc/Rprofile.site" (with and without the environmental variable R_HOME set to the install directory of R 2.15.0 in advanced system settings): When I

Hello, All: What would it take to make ?iconv? portable? I ask, because I want to convert accented characters to vanilla ASCII, thereby converting, e.g., ?Ra?l? to ?Raul?, and Milan Bouchet-Valet suggested on R-help that I use 'iconv(x, ?", "ASCII//TRANSLIT?)?. This worked under Windows but failed on Linux and Mac. It?s part of the ?subNonStandardCharacters? function

Hello: rJava works for me under 32-bit but under not 64-bit R; see below. Suggestions?

Try re-installing Java and make sure R and Java have matching architectures.")

Hello, All: Do you know of any capability to substitute more then one byte in an object of class Raw? Consider the following: > let4 <- paste(letters[1:4], collapse='') > (let4Raw <- charToRaw(let4)) [1] 61 62 63 64 > (let. <- sub('bc', '--', let4Raw)) [1] "61" "62" "63" "64" > # no
