Unique Ordering
Hi R-Help,
data at bottom
I've been struggling with a problem where I need to order based on 1) the
Frequency "Freq" and 2) keeping each group of 3 of the same type together
"Var2" but I want across all groups it to go "high to low" based on the
earn factor.
Thank you!

Initiating in BNArray
Hi,
I'm trying to understand some details about an example maintened in [1].
According that link, I have total.data as a data set (am I right?).
But I don't understand how is built that table.
I saved the dataset in a file, with dput(), and had something like this:
structure(list(df.all = structure(list(V1 = structure(c(1L, 2L,
3L, 4L, 5L, 6L, 7L, 8L, 9L, 10L, 11L, 12L, 13L, 14L, 15L,

Hi all:
I am trying to use the ddply function to estimate the mean of 'Total','Fry','Smolt' and 'Fry.Eq' columns without success. I have the dput of my dataset below. I wonder if someone can give me a hand with this function.

Help with readBin
I'm trying to read a binary file created by a fortran code using readBin
and readChar. Everything reads fine (integers and strings) except for
double precision numbers, they are read as huge or very small number

far.
I also tried on R 64 bit for linux and windows (R 2.14) and R 2.11 on

MyModel <- auto.arima(MyTseries, d=1, D=1)
MyModelForecast <- forecast (MyModel, h=12)

Sadly you failed to set your email program to send plain text and the data is corrupted at my end.
I also think you need to reduce the size of the data set... the intent here is to increase your understanding, not debug your particular analysis.
I will say that I am having a very challenging time understanding what you are trying to accomplish though. What are the equations that you think need

... and the mailing list is picky about attachments... whatever you attached did not conform to the stringent requirements mentioned in the Posting Guide. Pasting the code right into the email is usually safest, though you DO have to post using plain text (as the Posting Guide indicates) or your code may get mangled by the automatic html format removal.

discrete hazard rate analysis
Dear R users,
I have more of a statistical/econometric question than straight R one.
I have a data set with the discrete hazard rate of small firms survival on
400 counties over a period of 9 years. This data was generated using census
information from the VAT registration number of each one of these business.
I would like to analyze the effect of regional factors (deprivation index,

Summarizing data containing data/time information (as factor)
Dear R user
I want to create a table (as below) to summarize the attached data
(Test.csv, which can be read into R by using 'read.csv(Test.csv, header=F)'
), to indicate the day that there are any data available, e.g.value=1 if
there are any data available for that day, otherwise value=0.

Unless there is good reason not to, always cc the list -- there are lots of
smarter folks than I on it who can help.
I may or may not have time to look at this. Hopefully someone else will.
