I guess I did sth wrong with the optional argument in the program. but I don't
know how should I make it.
in my main program:
source(getelasticity_overPB.r)
crossprice-getelasticity(mydata,mydatao,nest)$cross_p
is same with
crossprice-getelasticity(mydata,mydatao)$cross_p
I don't know why
In getelasticity_overPB.r:
I have the function:
getelasticity=function(mydata,mydatao,method=NULL){
.
source(runmodel.r)
rr-getrange(dataw,mydatao,method=NULL)
#I have tested that rr-getrange(dataw,mydatao) is different with
rr-getrange(dataw,mydatao,nest): which is what I want.
rr
}
how should I make it work???
Thanks for your help.
Kind regards,
Tammy

[R] Instrumental variables for the competitive price
Dear R user, I have been setting up the models for predicting the volume based on the price information of own product and competitive products. one option is to use instrumental variable to break price into two parts: one part that might be correlated with error term, and the another part that is not. But now I met the problem of choosing instumental variables. I have searched many papers. it has been mentioned that cost can be used as one instrumental variable for the price. yes. I can use cost for own price. but how about the competitive price's instrumental variables? I don't know their cost information at all except their price information and market share. I will be really appreciated if someone can suggest me the possible choices of instrumental variables for the competitive price? Thanks in advance.

[R] Please Help me!
Hi, R-users,
I have a problem: Because there are few files which can't be readed
into R completely, so on the following subsequence programme, I use
write.table, which creates the NA files for those incomplete files
autimatically.
I don't want those NA files.
My programes formats looks like:
name_c-Sys.glob(C:/Documents and Settings/lma/My
Documents/habitdata/*/calllog/*)
for (i in 1:length(name_c)){
log1-readLines(name_c[i])
write.table(Temps, file=paste(C:/Documents and Settings/lma/My
Documents/habitdata1,pname,lname,basename(name_c[i]),sep=/))
}
Error Information:
Error in file(file, ifelse(append, a, w)) :
cannot open the connection
In file(file, ifelse(append, a, w)) :
cannot open file 'C:/Documents and Settings/lma/My
Documents/habitdata1/NA/NA/NA': Permission denied
I have checked why the error appears, because when I use readLines to read
data, but when processing the large data set, there are few files which can not
be readed in completely:
48: In readLines(name_c[i]) ... :
incomplete final line found on 'C:/Documents and Settings/lma/My
Documents/habitdata/244052900243997/calllog/calllog_log-20050505T121611.txt'
...
So it create the NA file when implementing the subsequence procedure by
write.table.How can I do: whenever readLines can't completely read one file,
then autimatically doesn't implement the subsequence programmes?
Thanks.
Tammy

From the help page for readLines:
If the final line is incomplete (no final EOL marker) the
behaviour depends on whether the connection is blocking or not.
For a non-blocking text-mode connection the incomplete line is
pushed back, silently. For all other connections the line will be
accepted, with a warning.
You can disable the warning with;
readLines('your_file', warn = FALSE)

Hi,
I'm pretty sure you dont mean merge since merge() creates a new big data
frame from two small ones. It appears that you want to omit some rows.
As I said before, get used to selecting rows like this
data.frame-data.frame[data.frame$conditional.rows1000,]
(for example)
Although I dont have a clue what criteria you are using to select the rows
you want...

I couldn't use the method what the example gives. Because Data frame is
quite big, and it has so many rows which are repeated. I am not pretty
sure about the range of 1000. It turns out I should merge those row
which repeated.

Hi,
I'm pretty sure you dont mean merge since merge() creates a new big
data
frame from two small ones. It appears that you want to omit some rows.
As I said before, get used to selecting rows like this
data.frame-data.frame[data.frame$conditional.rows1000,]
(for example)
Although I dont have a clue what criteria you are using to select the
rows
you want...

Re: [R] who can give me some hint?
Thanks a lot for your reply.
I expect a more flexible solution. Because I couldn't check that column one by
one.
If another Rep colum is:
useractivity_act
2
2
3
3
3
4
5
5
6
useractivity_idle
i should be able to write a program to make it as:
useractivity_act
2
3
4
5
6
useractivity_idle
Only keep 1st value of repeated values.
I have been working no it for a whileStill didnt get solution.
Thanks for your concentration.

I assume the problem is to only keep those rows whose
Rep value is not equal to the Rep value in the prior row.
In that case just compare c(, Rep[-nr]) to Rep and
use the resulting vector, ix, to select out rows.
Rep - as.character(act_2$Rep) could
be simplified to Rep - act_2$Rep if Rep
is already known to be character.

Re: [R] Date frame
I have produced the data frame(1) as: starting_timeEnding_time session_1: 14:36:1014:40:44 session_2: 14:40:47 14:41:47 for each session, I produced different sequences as: seq_1-c(4 ,3, 0 ,3 ,4 ,1, 0 ,1 ,4 ,3 ,4 ,3 ,4) seq_2-c(3,4,1,2) seq_3-Null I want to put those to the 3rd column of data frame (1) corresponding the individual session. How could I do so? Originally, I want to create a data frame with each row contains different sequence and then put to 3rd column, which seems couldn't be done. thanks.
