as.integer and indexes error
Hello All,
I would like to report the following bug or maybe you can explain if I am
wrong.
I am sampling from two different populations with weights. The two
populations have the same age groups and I want to distinguish where I am
sampling from. That is why I am using a matrix such as:

noob requesting help
I'm fairly new to R and still learning how to use it. I could really use some
help with the following problem.
I have a huge .csv file containing thousands of measurements on 34 different

All birds have a different number (ranging from 121 to 542). All
measurements have a tripID (1 for the first trip of every bird, 2

Grouping and/or splitting
I have a dataframe imported from csv file below:
Houseid,Personid,Tripid,taz
1,1,1,4
1,1,2,7
2,1,1,96
2,1,2,4
2,1,3,2
2,2,1,58
There are three groups identified based on the combination of first and
second columns. How do I split this data frame?
I tried
aa <- split(inpfil, inpfil[,1:2])
but it has problems.
Output desired is
aa[1]
Houseid,Personid,Tripid,taz
1,1,1,4
1,1,2,7

Aggregate?
Hello,
I have a data set with a grouping variable (TRIPID) and several other
variables. TRIPID is repeated in some areas and I would like to use a
function like aggregate to sum the variable UNITS according to TRIPID.
However I would also like to retain the other variables as they are in
the data set with the new summed TRIPID.
So what I have is something like this:

How is everyone structuring stories?
Bleeding-edge story-writers,
How are you structuring your specs?
I am working on a new project and tried this:
./lib
./blah
./spec
./blah
./stories
But it breaks autotest, so I moved stories parallel to lib and spec.
Also what about suffixes?
I have adopted "xyz_story_spec.rb", and "xyz.story" for the time
being, with the line

storing output data from a loop that has varying row numbers
Hi All,
I am trying to run a loop that will have varying numbers of rows with each
output.
Previously I have had the same number of rows so I would use (and I
appreciate that this will no doubt achieve some gasps as being thoroughly
inefficient!):
xdfrow<-(0)
xdfrow1<-(1:32)
xdfrow2<-(33:64)
xdfrow3<-(65:96)
xdfrow4<-(97:128)
xdfrow5<-(129:160)
xdfrow6<-(161:192)

subset
Hello everyone,
I have a large dataset (x) with some rows that have duplicate variables
that I would like to remove. I find which rows are the duplicates with
X1<-which(duplicated(x)). That gives me the rows with duplicated
variables. Now, how can I remove just those rose from the original data
frame. I think I can create a new data frame without the duplicates
using subset. I have tried:

Sortable
I have 3 sortables, namely lista, listb and listc. Lista being a static list
of items and will be drag n drop to listb and listc. Everytime I drag from
lista to either listb or listc, the items in lista will be removed. Is that
normal? If so, can anyone advice how can I maintain the items in lista so
that I can have duplicate items in listb and listc.
I am using rails for the development.
