Thanks very much to Friedrich Leisch, Brian Ripley and Thomas Lumley for their useful answers. Basically, they all suggested creation of a personal package as the easiest and best way to hold ones own functions. This indeed is quite easy and very useful. In addition, Friedrich Leisch pointed out that he's planning to add an "append" argument to the dump() function. One follow up

Dear r-helpers! I have trouble reading data from an Oracle data base using RODBC Version 1.0-3, R Version 1.7.1, Windows XP, Oracle8 ODBC Driver Version 8.1.6.4.0: > library(RODBC) > channel <- odbcConnect(dsn="PAV32", case="oracle", believeNRows=FALSE) > # ok, this was succesful > x <- sqlTables(channel) > x[37, ] TABLE_CAT TABLE_SCHEM TABLE_NAME

Dear R users! I am using R Version 1.7.1, Windows XP, package "foreign" (Version: 0.6-1), SPSS 11.5.1. There is one thing I noticed with "read.spss", and I'd like to ask if this is considered to be a feature, or possibly a bug: When reading character columns, character strings seem to get filled with blanks at the end. Simple example: In SPSS, create a file with one

Dear R community, I am using function 'within' in R.2.9.1 to add variables to an existing data.frame. This works wonderful, except for one minor point: The new variables are added to the data in reverse order. For example: x <- data.frame(a = 1:3, b = 4:6) y <- within(x, { c = a^2 d = b^2 e = c+d } ) gives a b e d c 1 1 4 17 16 1 2 2 5 29 25 4 3 3 6 45 36 9

Dear R-users! I am using R 1.7.0, under Windows XP. Having some hospital discharge data (admission date and discharge date for each patient), I want to get the number of patients in the hospital on a given date. My data look like (simple example): > x <- data.frame(patid=c("pat1", "pat2"), adm.date = c("15.03.2002", "16.03.2002"),

Dear R-users! I would like to search for "association rules" (and compute support and confidence, for example) in a data set, and wonder if this can be done with R (version 1.5.0 for Windows)? Particulary, I wonder if a) anyone has done something like that with R or b)maybe someone has written an R-interface to some existing algorithm/software (e.g. to something like the

Hello, I am working with R version 2.10.1 under windows. In a text file, I need to replace all characters at certain column positions with blanks. For example, say the file contains two lines and looks like this: ab34cd78e fg3 hi78j I'd like to replace everything at positions 3-4 and 7-8 with blanks, so the output should be: ab cd e fg hi j [I'm not sure if this is really an R

Dear R-users, I am working with R version 2.10.1. Say I have is a simple function like this: > my.fun <- function(x, mult) mult*sum(x) Now, I want to apply this function along with some other (say 'max') to a simple data.frame, like: > dat <- data.frame(x = 1:4, grp = c("a","a","b","b")) Ideally, the result would look something like

Hello, does anyone have experience with reading SPSS Version 15.0 files into R (version 2.4.1, WinXP)? I have long been sucessfully reading SPSS files with read.spss from the wonderful foreign package, but somehow after upgrading from SPSS14 to SPSS15 I seem to have problems. Trying a simple example, where test.sav is a SPSS 15.0 data file consisting of x1=c(1,2,3) and

Dear R-community, using R.2.9.1, how do you put reference lines or grids into the _background_ of a plot? For example: barplot(3:1) abline(h = seq(0.5, 2.5 ,0.5), col = "red", lty = "dashed") -> The lines are before the bars (and the line parts going through the bars might be considered as "chart junk", I suppose). Now, in this toy example I could just do the

Dear R-users, I am using R version 2.9.1 and lattice 0.17-26 under windows. In a lattice boxplot, I would like to add information on how many observations each singel boxplot is based upon. For example (the basic plot): # Begin R-code library(lattice) dat <- data.frame(panvar = rep(c("A","B","A","B"), c(3,7,4,6)), grp = rep(c("grp1",

Dear R-people! I am using R 1.8.0, under Windows XP. While using ISOdate() and strptime(), I noticed the following behaviour when "wrong" arguments (e.g., months>12) are given to these functions: > ISOdate(year=2003,month=2,day=20) #ok [1] "2003-02-20 13:00:00 Westeurop?ische Normalzeit" > ISOdate(year=2003,month=2,day=30) #wrong day, but returns a value [1]

Dear R-users! I am using R 1.7.0, under Windows XP; I also have Internet Explorer 6.0.2600.0000, Norton AntiVirus 7.60.926. Our firewall seems to want to "protect" me from downloading precompiled packages for Windows. When I try to download packages, like http://cran.at.r-project.org/bin/windows/contrib/1.7/RODBC_1.0-3.zip for example, I am not allowed to and get a message like this:

Ok, one last try.

(Before starting: I'm a total R noob so please bear with me in case of any error or faux pas). Hi, For a small project, I'm writing a few simple R functions and calling them from python (using RPy). I'm sharing the code with a couple of friends, using a subversion server. Now, I want something like a package, to be able to share functions between ourselves. Having read a few package

Dear R users, this is a question for R version 1.2.0 under Windows NT 4.0, regarding the documentation of ones own functions. I have ceated a private library for my functions, which works all very well, apart from that I am not able to create appropriate help files. For illustration, here is a simple example of where I'm stuck: > # first, create a simple function f1: > f1 <-

Hello I was wondering if it was possible to enter R commands from an external text file. If it is possible, it will be easy for repetetive tasks. Does anyone have an idea ? thanks in advance Ahmet Temiz TURKEY ______________________________________ ______________________________________ The views and opinions expressed in this e-mail message are ...{{dropped}}

Hello, What options are available for me to debug my R scripts? For example I normally do something like >source("myfunctions.R") >function1("height", "weight") myfunctions.R is a large R source file that contains many functions. function1 is the "main" function in myfunctions.R. It calls many other user-written functions that are also in

Dear R community, I am using R 2.1.1 on Windows XP, package lattice Version 0.12-5, and want to add text (sort of a dat-stamp actually) to the lower left corner of a lattice plot, prefarably _after_ the plot has been created. Here is a simple example what I do in base graphics: # base graphics: > plot(rnorm(100), rnorm(100)) > mtext(as.character(Sys.Date()), side = 1,line = -2, outer = T,
