survival
Dear R-helpers,
We marked 6000 leaves from 5 SPECIES - 10 individuals/species - in two
different TREATMENTs: a control and a dry-plot from which 50% of
incoming precipitation was excluded. We followed those leaves for 42
months and noted the presence and absence at each visit. I then carried
out a Cox Harzard model to see differences in leaf mortality between
parcels and among species over time:

problem with using apply for dataframe
Dear people,
I am including an example of a dataframe:
mydataframe<-data.frame(X=c(1:4),total_bill=c(16.99,10.34,21.01,23.68),tip=c(1.01,1.66,3.50,3.31),sex=c("Male","Male","Male","Female"))
When I use the sapply function getting the information about the factors
works:
sapply(mydataframe,function(x)is.factor(x))
X total_bill tip

ggplot facet label font size
How do I change the font size in the facet labels along the edges of the
plot?
For example (from the ggplot help file):
p<-ggplot(tips, sex ~ smoker, aesthetics=list(x=tip/total_bill))
gghistogram(p)
In this plot, the facet labels are "smoker: No", "smoker: Yes", "sex:
Female", "sex: Male". What command can I use to reduce the font size of

ggplot2 axis color
Hi:
Does anyone have an idea on how to color the axis and
labels using ggplot2? This is what I got:
library(ggplot2)
p <- qplot(total_bill, tip, data = tips)
NewPlot<- p + geom_abline(slope=c(0.1,0.15,0.2),
colour=c("red","blue","yellow"),size=c(2,5,2))
NewPlot + geom_smooth(colour="green",
size=3,linetype=3)

how do i retrieve a newly created id
in my code i''m calling save on an object. The id gets created as the object
is persisted. How can i retrieve that newly created id? I guess I could
query the table again using the other attributes of the object but is there
another way?
thanks in advance.

Previously extended schema not working in 4.4.0
Thank you, Andrew - I hadn't done so. (In a good way, I haven't yet had
problems with samba that have caused me to delve quite so deeply into the
DB :) so I'm not as familiar with the range of tools as I could be, sorry!)
This has flagged up quite a few errors, all along the lines of:

diff of two timestamps
Hi all,
I have the following problem: I have a csv-file consisting of timestamp
values (no dates), e.g.:
Timestamp1;Timestamp2;
05:24:43;05:25:05;
15:47:02;15:47:22;
18:36:05;18:36:24;
15:21:24;15:22:04;
I need a vector with the difference of the two timestamps, so I read the
data with the read.csv-function:
myObj <- read.csv("file.csv",header=TRUE,sep=";").

Reference classes: accessor functions via 'getRefClass(...)$accessors(...)'

I am defining S4 objet. Is it possbile to define a method that change

Help! Big problem when using "browser()" to do R debugging?
Hi all,
Could you please help me?
I am having the following weird problem when debugging R programs
using "browser()":
In my function, I've inserted a "browser()" in front of Step 1. My
function has 3 steps and at the end of each step, it will print out
the message "Step i is done"...
However, after I hit <ENTER> when the program stopped before Step 1

WishList: Remove Generic Arguments
I apologize if this issue has been raised before.
I really like object oriented S3 programming.
However, there's one feature of object oriented S3 programming that I don't
like.
Generic functions can have arguments other than dots.
Lets say you have an R package with something like:
print.myfunction (f, ...)
{ dosomething (f, ...)
}
Noting that I use function objects a lot.

Simple act_as template
Hello !
I posted a simple template to show how to add ''act_as_whatever'' to
ActiveRecord.
I think this might be useful to others as there are some trickery ruby
things in this

Here is the template : http://textsnippets.com/posts/show/384

Dots argument in apply method
Hello everyone,
I'm working on a package using S4 classes and methods and I ran into the
following "problem" when I tried to create an "apply" method for objects
of one of my new classes. I've found a way around the problem but I
wonder if I did not paint myself into the corner. I'd like your opinion
about that.

can a class find out it''s instance name?
Hi friends - a javascript question....
Does the prototype object add some way for a class to find out the
variable name of its instance variable?
Or does javascript have some built in way to do this?
This is confusing to describe - but if I define a variable as some
object:
var myVariable= new Widget(''fdfa'');
can some built-in method inside the Widget class be

"registering" a generic method for a class
Sorry in advance if this is too simple a question, but I'm stuck with
some odd behavior and I can't find the text to rid myself of this
(admittedly somewhat trivial) problem. Note that I've done generic
programming with S3 "objects" in the past, but I've never really
dabbled in creating S4 objects until now.
So, I've created a new S4 class, call it

Previously extended schema not working in 4.4.0
Hi,
About a year ago (I think I was using v4.2.x at the time), I extended the
schema of my Samba AD. This worked just fine and since then I have been
able to create and edit objects from my custom schema via ADSIEdit. This
worked fine under 4.3.x as well - the last such object I successfully
created was just over two months ago, at which point I was running some
variant of 4.3.x (probably 4.3.5).

change the names of all listed objects
Dear list members,
I have created seven objects, from a to g, so that ls() gives me
[1] "a" "b" "c" "d" "e" "f" "g"
how can I automatically change their names in
"a1" "b1" "c1" "d1" "e1" "f1" "g1"
It seems simple, ut it is driving me mad.
Thank you very

Huge performance difference between implicit and explicit print
Hi all,
Can anyone help me understand why an implicit print (i.e. just typing
df at the console), is so much slower than an explicit print (i.e.
print(df)) in the example below? I see the difference in both Rstudio
and in a terminal.
# Construct large df as quickly as possible
dummy <- 1:18e6
df <- lapply(1:10, function(x) dummy)
names(df) <- letters[1:10]
class(df) <-
