find date between two other dates
Hi,
I am trying to assign "Season" values to dates depending on when they occur.
For example, the following dates would be assigned the following "Season"
numbers based on the "season" intervals detailed below in the code:
ddate Season

02/01/1999 05:20:44 2

Remove records from a large dataframe
Hi, I am trying to remove a series of records from a large dataframe. The
script I have written works fine but takes a long time to run. Can anyone
suggest a quicker way to do this?
Here is an example of the code I've written. The end result of this bit of
code would be a dataframe with any records relating to ID 1 or ID 4 removed:
#dataframe
id <- c(1,1,1,1,2,2,2,2,2, 3,3,3, 4,4)

multinom and contrasts
Hi,
I found that using different contrasts (e.g.
contr.helmert vs. contr.treatment) will generate
different fitted probabilities from multinomial
logistic regression using multinom(); while the fitted
probabilities from binary logistic regression seem to
be the same. Why is that? and for multinomial logisitc
regression, what contrast should be used? I guess it's
helmert?
here is an example

adding value labels on Interaction Plot
Hello - and sorry for what might look like a simple graphics question.
I am building an interaction plot for d:

How to open more windows to make more graphs at once!
Dear R users,
I have a data frame (test) including five columns of upper (numeric), lower (numeric), observed (numeric), best_sim (numeric) and stname (factor with 80 levels, each level with different length). Now I would like to write a short program to draw one graph as follow for each level of stname but I would like also to draw each time 12 graphs for the 12 levels of stname in the same

combine the data frames into comma separated list.
Hi R users,
I am new to R and am trying to merge data frames in the following way.
Suppose I have n data frames each with two fields. Field 1 is common among
data frames but may have different entries. Field 2 is different.
Data frame 1:
Src Target1
1 aaa
1 bbb
1 ccc
2 aaa
3 ddd
Data frame 2:
Src Target2
2 aaaa

readBin or writeBin adds extra nulls (PR#2333)
Full_Name: Ken Yap
Version: 1.6.1
OS: Linux (SuSE 8.0)
Submission from: (NULL) (129.78.64.5)
I'm trying to copy a file using readBin and writeBin. (The reason is to be able
to pipe PostScript or PDF output to a socket later, this is just an experiment.)
I do:
zz <- file("foo.ps", "rb")
r <- readBin(zz, character(), 1000000)

xen domU ID and static routing
Hi,
I use a EQ 4 dedicated root server by hetzner with ubuntu jaunty. I
installed xen 3.3 with debian kernel and brought up 3 domUs.
Now comes networking...
Hetzner does not allow bridged networking so I have to use routed mode
in xen. No Problem so far, but the Problem actually is:
When I bring up a domU the routing table is created by the xen-script

Estoy trabajando con una densidad conjunta algo elaborada (suma y cociente
de dos variables aleatorias positivas usando la cópula Frank) y requiero
encontrar la distribución marginal de cada una de las variables. A manera de
ejemplo (no es el caso específico, que tiene mucho más código), si partimos

How to make a table of a desired dimension
Hi ComRades,
I want to make a matrix of frequencies from vectors of a continuous
variable spanning different values. For example this code
x<-c(runif(100,10,40),runif(100,43,55))
y<-c(runif(100,7,35),runif(100,37,50))
z<-c(runif(100,10,42),runif(100,45,52))
a<-table(ceiling(x))
b<-table(ceiling(y))
c<-table(ceiling(z))

Rcmdr and scatter3d
Hi folks,
I'd like to use scatter3d (which is in R commander) to plot more than one
dataset in the same graph, each dataset with a different color. The kind
of stuff you would do with "holdon" in Matlab.
I read a recent message that was posted to this list with a similar
problem, but I couldn't understand the reply. Could someone give me one
example? How do you plot subgroups

No logging with chain logdrop and logreject
Hello:
I just started using Shorewall this morning and must say that I''m very
impressed. Much nicer than what I was using previously.
I love the ability to type ''shorewall logdrop ww.xx.yy.zz'' and
completely block a particular IP address. However, the log part doesn''t
happen. When I look in the logdrop chain, there is no LOG prefix.
