Full_Name: Stefan Albrecht Version: 2.7.2 (and 2.8.0) OS: Windows NT Submission from: (NULL) (194.127.8.17) Dear R Debug-Team, in write.csv() it is not possible to set both row.names = FALSE, col.names = FALSE since the col.names = FALSE gets overwritten: > write.csv function (...) { Call <- match.call(expand.dots = TRUE) for (argname in c("col.names", "sep",

Hello all, I had some trouble recently with write.csv because I couldn't change one of the default options. A quick view of the code showed that the function was not defined in the most optimal way. Currently, write.csv <- function (..., col.names = NA, sep = ",", qmethod = "double") write.table(..., col.names = NA, sep = ",", qmethod = "double")

Hi, I am writing a function that writes to a csv file for every call. However, for the subsequent calls, I want to append the data to the existing csv file without appending the column names again. I tried searching in the previous posts, but I am stuck with different errors. Here is what I am doing (dataF is a data-frame):- outputFilePath <- paste(getwd(), "/",

Thanks to all who have responded. My concern was to be able to write a csv file that can have line feeds in string columns chr(10). Why? Excel allows line feeds chr(10) within cells and line breaks chr(13)+chr(10) at line ending, but the windows version of R automatically replaces \n by \r\n in writing and \r\n by \n in reading (text mode). The clues for a solution came from Brian Ripley and

The write.csv() function is currently implemented as function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=NA, sep=",", qmethod="double") } Surely, it should be function (..., col.names=NA, sep=",", qmethod="double") { write.table(..., col.names=col.names, sep=sep,

Hi everyone, I''m trying to convert a string passed on the command-line into an ActiveRecord class, so I can do something like this. a="SomeClass" a.find(:all) where class SomeClass < ActiveRecord::Base end This appears to work (better ways would be appreciated): a="SomeClass" b=eval a b.find(:all) However I would like to make sure

Looks like I?m bumping a lot into unexpected behaviour lately, but I think I found a bug again, but don?t have access to Bugzilla: Write.table (from core-package utils) doesn?t handle nested data.frames well, the quote arguments only marks top-level character (or-factor columns) for quoting, so this fails: df <- data.frame(a='One;Two;Three',

Does anyone have any experience making this work? I installed the plugin and tried the following: class SomeClass < ActiveRecord::Base acts_as_Taggable end class SubClass1 < SomeClass end class SubClass2 < SomeClass end SubClass1.tag_with("tag") and notice that taggable_type = SomeClass when I do SubClass2.find_tagged_with("tag") a SubClass1 object is

Hi,   I'm new to R and S4 classes. I defined a class with two methods (myMethod1 and myMethod2). I want to call myMethod1 within myMethod2. Why does the code below not work? The name 'myMethod1' doesn't appear to have meaning inside myMethod2, even though the two methods belong to the same class.     setClass(Class="SomeClass",      representation=representation(      

Dear useRs and wizaRds, I am currently developing a set of functions using S4 classes. On the way I encountered the problem exemplified with the code below. For some reason the 'validity' method does not seem to work, i.e. does not check for errors in the specification of the slots of the defined class. Any hints? My understanding of the whole S4 system was that validity checks are made

I''m trying to figure out how to use modules with my model classes. I''m going to have good number of model classes that don''t map to the database, and I''d like to put some of these in seperate modules. I''ve been wrestling with this for 2 days and can''t figure out how to get it to work. Rails seems to handle it fine for controllers, though. I

Hi Accesses the $new method for a class defined in a package fails if the methods package is not loaded. I have created a test package with the following single code file: newTest <- function() { cl <- get("someClass") cl$new } someClass <- setRefClass("someClass") (This is similar to code actually used in the testthat package.) If methods is not loaded,

FWIW, I''ve wrote puppet-cleaner to help me make comply thousands of lines of puppet 2.6 DSL code to puppet 2.7 style guide and expectations. I''m uploading it to github today for anyone to use. https://github.com/santana/puppet-cleaner Externally, you run puppet-clean file.pp and it can transform this: /* multiline comment trailing white space here -> */ class

Hi there My script at each iteration produces a .dat file which I save in a directory with write.table. Then I need to read each line of this file and create a directory for each line and put elements of that row in that directory. I do it with the following script which I have inserted somewhere between my outer iteration loop, it works fine for the first iteration, but the problem is that it

Full_Name: Kingsley Oteng-Amoako Version: 2.5.1 OS: Windows 5.1.2600 (Windows XP) Submission from: (NULL) (203.185.215.144) The col.names=false in the write.csv command does not work as documented. Attempting to write a vector to a csv file without column headers does not work as documented. The col.names=false feature on the write.table command does however work and it can thus be coerced

Hi R experts,   The fix() function canbe used to edit normal functions. I would like to know whether it's also possible to use something similar to edit a method of an S4 class. In other words, is there a fix-like function that allows me to edit method definitions without having to go back to the source code?   setGeneric (name="doStuff",def =

Hello,   How can I generate an overview/vector of all the methods winthin an S4 class? Similar to dir() in this Python code: >>> class SomeClass():  def some_method_1(self):   pass  def some_method_2(self):   pass   >>> dir(SomeClass) ['__doc__', '__module__', 'some_method_1', 'some_method_2'] >>>   Thanks in advance!
