write.csv(..., col.names = FALSE) (PR#13202)
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",

write.csv suggestion
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")

Append to csv without header
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):-

Summary: How to represent pure linefeeds chr(10) under R for Windows
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

write.csv (PR#7992)
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")
{

convert string to AR class
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

write.table with quote=TRUE fails on nested data.frames
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',

acts_as_taggable with single-table inheritance?
Does anyone have any experience making this work? I installed the
plugin and tried the following:

SubClass1.tag_with("tag")

VERY basic question about S4 classes
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.

initalizing and checking validity of S4 classes
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

using modules with models?
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.

$new cannot be accessed when running from Rscript and methods package is not loaded
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.)

readLines problem in iteration
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

Col.names parameter in write.csv (PR#10411)

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

fix()ing an S4 method
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?
