[Bug] Seg Faulting in index.rb:718
Hey,
Ferret is repeatedly seg-faulting my mongrel servers on the same line:

I''m using ferret 0.10.11. I haven''t had the time to dig into yet, it''s
on the backburner right now - I just keep several spare servers and
restart them

Lightbox and RJS
Hi,
I am trying to include lightbox functionality in my app, but there is
a slight complication. Apparently lightbox initializes all the links
to lightbox events on page load. However, in my case, some new links
to lightbox events will be rendered to the page through ajax events
(obviously this means after the page loads). So I figure I need to
find a way to call lightbox''s

Win XP / Ferret & Acts_as_ferret .dump problem
Hey,
Has anyone managed to bypass or fix the ferret''s .dump method problem?
When I include acts_as_ferret my whole rails app just blows up because
of Ferret''s .dump method. Ex:

Replacing for loop with tapply!?
Dear all,
We have a large data set with temperature data for weather stations
across the globe (15000 stations).
For each station, we need to calculate the number of days a certain
temperature is exceeded.
So far we used the following S code, where mat88 is a matrix containing
rows of 365 daily temperatures for each of 15000 weather stations:
m <- 37
n <- 2

sum(row1==y) if row2=x
Hi to all
is there any construct to sum
data=data.frame(row1=c(1,1,3,1,2,3,2,2,1,3,4,5,2,3,2,1) ,
row2=c(2,2,1,1,1,2,1,2,1,1,1,1,2,2,2,1) )
Means I would like to get all y of row1 if in row2 of the data.frame is
an x
f.e row1=3 and row2=2
so I would like to get 6
And is there another construct to get the count of pairs where
row1=3 and row2=2
means the result should be

Hi R-experts,
I try to find a way to transfer a matrix to a data.frame that is used as input of aov.
can you give me advice for that?

converting a data-frame by a defined rule
Hi,
I have a data frame with several columns.
Now I want to transfer the data into a new variable (also a data
frame), but I only want a part of the data, defined by a rule ...
for example; I have following data frame:
row1 row2 row3
x 2 3
x 1 4
y 5 3
y 2 3
I know want a data frame, only with lines containing x in row1.
I know how to do that for one row (f <-

generating multiple sequences in subsets of data
I'm running into a problem I can't seem to find a solution for. I'm
attempting to add sequences into an existing data set based on subsets
of the data. I've done this using a for loop with a small subset of
data, but attempting the same process using real data (200k rows) is
taking way too long.
Here is some sample data and my ultimate goal

Adding RcppFrame to RcppResultSet causes segmentation fault
Hi,
I'm a bit puzzled. I uses exactly the same code in RcppExamples
package to try adding RcppFrame object to RcppResultSet. When running
it gives me segmentation fault problem. I'm using gcc 4.1.2 on redhat
64bit. I'm not sure if this is the cause of the problem. Any advice
would be greatly appreciated. Thank you.

data.frame: how to extract parts
Hi,
I have a problem with the R syntax.
It's perhaps pretty simple, but I don't understand it ...
I can extract a column from a data.frame with the following code for
example ...
b$row1[b$row1 == "male"]
so I see all male-entries.
But I cannot extract all lines of a data.frame depending on this
criterium;
only.male <- b[b$row1 == "male"]
With that, I

Automagic number of views/clicks?
Hey,
Just wondering.. Are there are any automagic constructs in rails for
keeping track of number of views/clicks associated with the record? For
example, created_at and updated_at are automagically updated on edit/new
actions, are there any similar constructs for clicks/views of the
record?
Thanks.

for loop help please!
Hi Everyone,
I have a 2-dim data.matrix(e.g., table1) in which row1 specifies a range of
values. row2 - rown specify the number of times I want to replicate each
corresponding value in row1. I can do this with the following function:
rep(c(table1[1,]),c(table1[X,])) #where X would go from 2 - n.
Now, I can do this manually by changing the values of X and save each
resulting array/vector in

Creating named.list from two matrix columns
Hi Friends,
I am new to R.
On R utility class pages, creating "named.list" is described with this command :
new("named.list",a=1,b=2)
For large matrix having two columns, such as :
"row1" 2334
"row2" 347
"row3" 379
...
I want to create a named.list like :
$row1
[1] 2334
$row2
[1] 347
...
Can anyone explain how "named.list"

combine two columns
Hi,
I have an R programming problem and I havent found anything in the
documentation yet:
I have a data matrix, in which two neighbouring columns represent
replicates of the same experiment, e.g. something like this:
A A B B C C
row1 1 1 1 2 2 2
row2 1 1 1 1 1 2
I would like to test, if the values for the two replicates in a row
are the same or if they differ and generate a new

dividing values of each column in a dataframe
Hey Guys
I want to divide(numerically) all the columns of a data frame by
different numbers. Here is what I am doing but getting a weird error.
The values in each column are not getting divided by the corresponding
value in the denominator vector instead by the alternative values. I
am sure I am messing up something.
Appreciate your help

Hi Rui. Thanks for answer, I'm aware of drop = FALSE option. Unfortunately
it doesn't resolve the issue - I'm expecting to get a vector, not a matrix .

restricted bootstrap
Hello List,
I am not sure that I have the correct terminology here (restricted
bootstrap) which may be hampering my archive searches. I have quite a large
spatially autocorrelated data set. I have xy coordinates and the
corresponding pairwise distance matrix (metres) for each row. I would like
to randomly sample some number of rows but restricting samples such that the
