cumulative sum by group and under some criteria
Thank you very much for your reply. Your code work well with this example.
I modified a little to fit my real data, I got an error massage.
Error in split.default(x = seq_len(nrow(x)), f = f, drop = drop, ...) :
Group length is 0 but data length > 0

i param in "for" loop does not takes zeros?
Hi all
Is there any reason why the parameter i in a "for" loop ignores a value of
zero? For example
sim=c()
p=.2
for(i in 0:5)
{sim[i]=dbinom(i,5,p)
}
sim
[1] 0.40960 0.20480 0.05120 0.00640 0.00032
In this example the quantile i= 0 was ignored since
dbinom(0,5,p)
[1] 0.32768
The same behaviour occurs if I use a while loop to perform the same
calculation:
sim=c()
p=.2
i=0

Rails 2.3 memcache performance drop
After much effort I upgraded our fairly large Rails app from 2.1 to
2.3. After deployment yesterday I noticed an across the board
increase in response times. It seems that every call to memcache now
takes 10x longer than before. Here are some example numbers from my
development log (below), with memcache running locally. We see
similar scale of performance drop in production as well - average

Automatic rounding of values after factors , converted to numeric, are multipled by a real number
I am wondering if someone would have any suggestion about my issue?
I have the following code:
wgts<-aggregate(subset(lendata,select=c(Length)),list(lendata$Cruise,len
data$Station,lendata$Region,lendata$Total),mean)
wgts<-wgts[order(wgts$Group.3,wgts$Group.1,wgts$Group.1),]
names(wgts)<-c("Cruise","Station","Region","Total","MLen")

Fun with Webrick
Hi everyone,
I''m having some issues with a RoR app where webrick just completely
crashes. No warnings, no errors - just *crash*! Doesn''t matter what
I''m doing in the system, it just randomly craps out.
I''ve checked the development.log file, and everything appears normal.
The last few lines are:

intermittent failure of ability to connect to samba share from win (NT/2k) client

Creating Optimization Constraints
Good afternoon,
In the code below, I have a set of functions (m1,m2,m3,s1,s2, and s3) which represent response surface designs for the mean and variance for three response variables, followed by an objective function that uses the "Big M" method to minimize variance (that is, push s1, s2, and s3 as close to 0 as possible) and hit targets for each of the three means (which are 0, 10,

Garch Warning
Dear all R-users,
I wanted to fit a Garch(1,1) model to a dataset by:
>garch1 = garch(na.omit(dat))
But I got a warning message while executing, which is:
>Warning message:
>NaNs produced in: sqrt(pred$e)
The garch parameters that I got are:
> garch1
Call:
garch(x = na.omit(dat))
Coefficient(s):

Which is faster, calling helpers or rendering a partial?
Using partials is a nice way to separate chunks of content into
separate pages as opposed to building strings in helpers, but I''m
wondering which is faster. It scares me when I see stuff like:
Rendered users/_public (0.00051)
Rendered users/_public (0.00009)
Rendered users/_public (0.00008)
Rendered users/_public (0.00008)
Rendered users/_public (0.00008)
....50 more times
