Listing tables together from random samples from a generated population?
.
HI there,
I'd like to show demonstrate how the chi-squared distribution works, so I've come up with a sample data frame of two categorical variables
y<-data.frame(gender=sample(c('Male', 'Female'), size=100000, replace=TRUE, c(0.5, 0.5)), tea=sample(c('Yes', 'No'), size=100000, replace=TRUE, c(0.5, 0.5)))
And I'd like to create a list of 100

change function scope?
I'm still getting used to R's scoping. I've run into the following situation
value=0
thefunction <- function() print( value )
somefunction <- function() { value=99; thefunction() }
somefunction()
now, I understand that somefunction() returns 0 because thefunction() was
defined with value=0 in its parent envrionment, it dosent look at all in the
environment of somefunction. My

Convert "ragged" list to matrix
Hi,
I have a list made up of character strings with each item a different
length (each item is between 1and 6 strings long). Is there a way to
convert a "ragged" list to a matrix such that each item is its own row?
Here is a simple example:
a=list();
a[[1]] = c("a", "b", "c");
a[[2]] = c("d", "e");
a[[3]] = c("f",

Convert ragged list to structured matrix efficiently
Hi All,
I'm wanting to convert a ragged list of values into a structured matrix for
further analysis later on, i have a solution to this problem (below) but
i'm dealing with datasets upto 1GB in size, (i have 24GB of memory so can
load it) but it takes a LONG time to run the code on a large dataset. I
was wondering if anyone had any tips or tricks that may make this run
faster?

Adding ranks to a repeatedly ragged array
How can I add an extra column containing the rank
to a ragged array indexed by more than one grouping
factors?
E.g. with the barley dataset:
How can I to add an additional column ``rank''
containing the rank of the ``yield'' of
the different varieties in relation to the indices
``year'' and ``site'' to the barley dataframe?
I achieved to calculate the ranks with:

question: ragged array
Hello,
I have a big problem which I’m just not able to solve.
I created the following mean value from the following dataset structure:
Id |value
1 | 2
1 | 3
1 | 4
2 | 2
2 | 1
3 | 5
4 | 3
etc.|etc.
with the command:
mean_rating <- tapply(ratok$value, ratok$project_id , mean,simplify = FALSE)
this gives me a ragged array:
> mean_rating [1]

Output mis-encoded on Windows w/ RGui 3.5.1 in strange case
Thanks, I can now reproduce and it is a bug that is easy to fix, I will
do so shortly.
Fyi it can be reproduced simply by running these two lines in Rgui:
list()
encodeString("apple")

ragged data.frame? using plyr
I have a dataset that looks like:
set.seed(144)
sam<-sample(1000,100)
dat<-data.frame(id=letters[1:10],value=rnorm(1000),day=c(rep(1,100),rep(2,100),rep(3,100),rep(4,100),rep(5,100)))
I want to "normalise" it using the following function (unless you have
a better idea...):
adj.values<-function(dframe){
value_mean<-mean(dframe$value)
value_sd<-sd(dframe$value)

ragged array with append
I wonder what's the right way in R to do the following -- placing
objects of the same kind together in subarrays of varying length.
Here's what I mean:
> word <- c("a","b","c","d","e","f","g","h","i","j")
> kind <- c(1,1,1,2,3,4,5,5,7,7)

statistics for ragged arrays: loop to vector
Dear R users,
I am currently writing a MCMC algorithm for spatial Poisson model. One
problem which I need to solve is as follows:
I have a vector X[1:J] which describes characteristics of cells of a
rectangular grid. Further, for each cell I have a list of adjascent
cells adj[] and the vector listing numbed of adjascent cells num[].
Thus if I want to list cells adjascent to cell i I write

Output mis-encoded on Windows w/ RGui 3.5.1 in strange case
Sorry, I should have been more clear -- if I write the contents of
that script to a file called 'encoding.R' and source that, then I see
the reported behavior.
Here's something standalone that you should hopefully be able to copy
+ paste into RGui to reproduce:
code <- '
x <- 1
print(list())
save(x, file = tempfile())
output <- encodeString("apple")

how about a "<p-" operator?
I was cursing Matlab again today (what else is new) because the default
action for every Matlab command is to spew the result to the console,
and one must remember to put that darn ";" at the end of every line.
So I just wondered: was there ever a discussion as to providing some
modified version of the "<-" and "->" operators in R to do the reverse?

Ragged time series data
Hi and thanks in advance,
I am fairly new with R so I hope this problem isn't too amateur.
I have a vector of count data which correspond to vectors of date (%m/%d/%Y)
and time of day (%H:%M:%S).
I am trying to compute various statistics (e.g. daily max) by lumping the
data together by day. I have been able to utilize tapply() and group the
counts together, but with the method I use I end

Inverse of encodeString
What is the inverse of encodeString?
For example, \u1 is some Unicode symbol. If I do
s <- encodeString("\u1")
then s will be the string "\001". But anything I do
with s, will not return the Unicode that corresponds to \u1:
cat(s, "\n") # prints \001
cat("\u1", "\n") # prints y with umlaut

Fast lookup in ragged array
Hello,
I'm running an algorithm for graph structural cohesion that requires
a depth-first search of subgraphs of a rather large network. The
algorithm will necessarily be redundant in the subgraphs it recurses
to, so to speed up the process I implemented a check at each subgraph
to see if it's been searched already.
This algorithm is very slow, and takes days to complete on a

Multiple commands per priority
Hi everybody.
I have been searching and trying for an answer, but no luck, so here I go..
Is there anyway to execute multiple commands on a single priority in
extensions.conf?
eg:
exten => X.,1,Dial(SIP/1111) & somefunction(${EXTEN})
I need the dial command to dial internal extensions, and the
"somefunction" to
kick of our own outgoing system for redirection to outside lines;

Calling a null pointer. How undefined it is?
Hi all:
This question is related to a state machine generated by LLVM for a coroutine.
I stripped all coroutine related details to get to the essence of the question.
Let's say I have a state machine that looks like this:
struct State {
FnPtr Fn;
State() : Fn(&SomeFunction) {}
void Go() { (*Fn)(); }
void Stop() { Fn = nullptr; }
bool IsDone() { return Fn ==

default arguments and '...' in a function
Dear R-users,
I'm trying to work out a way to set default values for arguments in a function which includes the optional argument '...'.
In practice, I have a 'plot' method for a function which specifies different types of plots. Every different plot should have different default arguments (for example for 'col', 'ylim' etc), plus the argument '...' to
