ListCtrl help
Is there any sample code around that sorts a virtual listctrl?
I have loaded data into a ListCtrl and set things up so that if I
click on a column heading on_col_left_click(event) gets called and it

finding rows in a matrix that match a vector
Hi,
Please excuse my ignorance, but I am just learning R (this is my very first
day programming in R) and having a really hard time figuring out how to do
the following:
I have a matrix that is 1000 row by 6 columns (named 'table.combos') and a 1
row by 6 column vector (named 'mine'). I want to find every row in
'table.combos' that equals 'mine' and then count

what does cut(data, breaks=n) actually do?
Hello,
I'm trying to bin a quantity into 2-3 bins for calculating entropy and
mutual information. One of the approaches I'm exploring is the cut()
function, which is what the mutualInfo function in binDist uses. When it's
called in the format cut(data, breaks=n), it somehow splits the data into n
distinct bins. Can anyone tell me how cut() decides where to cut?
Thanks,

converting numeric into character strings
Hi,
Im trying to put some numbers into a dataframe , I have a list of numbers
(change points in a time series) like such
[1] 2 11 12 20 21 98 99
but I want R to recognise this as just a character string so it will put it
in one row and column, ideally I want them seperated by commas so I would
have for example

turning list into vector/dataframe
Hi,
I have used this command :
resamples<-lapply(1:1000,function(i) sample(lambs,replace=F))
resamples2<-lapply(resamples,Cusum)
to get a list of 1000 samples of my data. The function Cumsum is defined as
follows:
Cusum<-function(x){
SUM<-cumsum(x)-(1:length(x))*mean(x)
min<-min(cumsum(x)-(1:length(x))*mean(x))
max<-max(cumsum(x)-(1:length(x))*mean(x))
diff<-max-min

making multiple lines using qqplot
Hi Everyone,
I want to make 3 lines on the same graph (not as subplots, all in the same
window, one on top of each other) and I want them to be quantile-quantile
plots (qqplot). Essentially, I am looking for the equivalent of Matlab's
"hold on" command to use with qqplot. I know I can use 'points' or 'lines',
but these do not give me a qqplot (only appear to work

transient memory allocation and external pointers
Hello,
The Writing R extensions manual section 6.1.1 describes the transient
memory allocation function R_alloc, and states that memory allocated
by R_alloc is automatically freed after the .C or .Call function is
completed. However, based on my understanding of R's memory handling,
as well as some test functions I have written, I suspect that this is
not quite accurate. If the .Call

Sequences
Hi,
I am trying to make a sequence and am using a for loop for this. I want to
start off with an initial value ie S[0]=0 then use the loop to create other
values. This is what I have so far but I just keep getting error messages.
#To calculate the culmulative sums:
s<-rep(0,207) #as this is the length of the
vector I know I will have
