Hello all, I work for a company located in Madison, WI and we''re looking at replacing a pre-Struts J2EE ecommerce app with Rails. ''ve been using Rails with pleasure for the last year on several supporting applications, and I have everyone else convinced that it''s at least worth investigating. The developer team has a few experienced Java developers who are

Hi, I would like to use the beanplot() function from the beanplot package. Unfortunately, I can't find out how to suppress the dashed horizontal line, that shows the overall mean. In the help I've found the argument "overallline", but it only allows for "mean" or "median" . I have tried overallline = F, overallline="n", and

Dear all, I'm analysing a split-plot experiment, where there are sometimes one or two values missing. I realized that if the data is slightly unbalanced, the effect of the subplot-treatment will also appear and be tested against the mainplot-error term. I replicated this with the Oats dataset from Yates (1935), contained in the nlme package, where Variety is on mainplot, and nitro on

I don't understand why I get the following results. I define two classes 'Base' and 'Derived', the latter of which 'contains' the first. I then define a generic method 'test' and overload it for each of these classes. I call 'callNextMethod()' in the overload for Derived. From the output, it appears that the overload for Base gets called twice. Why is

Dear R Users, I have a couple of proto objects like: wedge <- proto(expr={ start.year <- 2008 end.year <- 2050 }) star.rating <- wedge$proto( star = c(4, 5, 8, 10), gain = c(0, .3, .5, .7), cost = c(0, 2100, 4000, 7500), star.rating <- function(., year) 6.0, setup = function(.){ .$cost.for.star <- approxfun(.$star,

Hi R Helpers, I am a long time RWinEdt user and have just acquired a new laptop. I have installed RWinEdt and things are going smoothly except for one small glitch - file names are not appearing on the document tabs. When I use WinEdt (as opposed to RWinEdt), they are appearing. Can anyone offer any advice on this? Thanks in advance, Simon Knapp OS: windows7 Arch: 64 bit R version: 2.13.0

Hi all, I am about to start a new RoR project. Which version of mysql is the current best one to use? I will be using the soon-to-be-released RoR 1.0 for the project. I really don''t want to start a PostreSQL vs. MySQL vs. Whatever war. I have all databases including Oracle at my disposal. This project will be my testbed for using RoR with mysql. I will be doing other tests with other dbs

Hi all, I am trying to make calls to R from an MFC application running on XP and am having problems blocking the application while the call executes. I have tried the following approaches to using R from the application (note that I set a wait cursor while R is executing). 1) call rcmd in BATCH mode using system(). This works well, except that I get the cmd window popping up... which makes the

I''m in the position that would be really useful for me to run in a testcase a test belonging to another testcase. Assuming I do not want to use modules, how could I do that? My code would be something like this: class MyTestCase < Test::Rails:TestCase def myTest matc = MyAnotherTestCase.new end end The code above seems to work but when I run MyTestCase all the tests

Hi List, Is it possible to define how 'in' works for an object of a specific class (to achieve a similar result to implementing the iterator protocol in a class Python)? Cheers, Simon Knapp [[alternative HTML version deleted]]

Dear list, I'm running windows xp with R 2.12.0. I'm trying to load a excel spreadsheet into R using the xlsx package. I posted my code below with the error I get. > res <- read.xlsx("Copy of test_excel_input_data.xlsx", 6) Error in .jcall("RJavaTools", "Ljava/lang/Object;", "invokeMethod", cl, : java.lang.IllegalStateException: Cannot get

Hi all, I'm just tried to start analysing some micro-array chips. And R was asking for this package. When I tried to install it it says that: Using R version 2.10.1, biocinstall version 2.5.10. Installing Bioconductor version 2.5 packages: [1] "hugene10stv1cdf" Please wait... Warning message: In getDependencies(pkgs, dependencies, available, lib) : package ?hugene10stv1cdf? is

I have a data frame of around 4500 rows which contain file name prefixes and other interesting variables. each prefix corresponds to multiple files and a I only have 4300 complete sets of files. If any one of the files is missing for a given prefix, then the function I use fails. The effect is emulated by the function "f" and data "dummy.data": f <- function(x) if(runif(1)

Hi, I'm using R2.8.1 in windows vista and the scan function to load in my data. That works all fine except that I get a message after the scan function finishes. It tells me how many items the function has read. For example "Read 202035 items". That would not be a problem but this is printed in the stderr stream which causes a problem in a different software I run the r scipt in. I

Hi all, I started recently to use R with linux(ubuntu) but I often get code written under windows or mac. I have two questions. When I encounter a function which is not in R linux what is the best way to find the right linux function for it? So next time I can help myself. I browsed the web for a long time and could not find anything to the the function zip.unpack. Thats actually my second

Background: I have an algorithm which produces a large number of small polygons (of the spatial kind) which I would like to use within R using objects from sp. I can't predict the exact number of polygons a-priori, the polygons will be grouped into regions, and each region will be filled sequentially, so an appropriate C++ 'framework' (for the point of illustration) might be: typedef

Dear friends, I have a table like this, I have A B C D ... levels, the first column you see is just the index, and there are different numbers in the table.

Hello everyone, I want to get a 1km by lkm grid raster image using my csv data. If I call latitude=a, longitude=b and preciptation=c. a<-(1,2,3,4,5) b<-(6,7,8,9,10) c<-(10,20, 30,40, 50) Then I found an example in r help which goes like pts = read.table("file.csv",......) library(sp) library(rgdal) proj4string(pts)=CRS("+init=epsg:4326") # set it to lat-long pts =
