RODBC missing values in integer columns
...IQ
database
sqlData = sqlQuery(connection, sqlString);
sqlData$ActionID might be 1,2,3,4,5,6,....150, 0,0,0,0,0,0,0,....,0,0,0,
301,302,303,304,.....448,449,500,0,0,0...,0,0
and Velocity will have data values along the whole column without these big
areas of 0's.
Thanks for the help,

relative file path
Hello,
Is there a way to find where a script is located within a script? getwd()
doesn't do what I want because it depends on where R was called from. I want
something like source("randomFile") and within randomFile there is a
function called whereAmI() which returns c:\blah\blah2\randomFile.R
In perl there is a library called FindBin and $FindBin::Bin has the
directory of the file

RODBC connection name
Hello all,
I've scoured the RODBC.pdf, but there appears to be no way to set the name
of the RODBC connection. This is useful for the DBA's to know that some
processes should only run for so long and can be automatically killed. But
currently the name is just R. so they aren't sure if the connection can be
automatically killed.
We are able to set this with our perl ODBC interfaces

rbind, data.frame, classes
Hi,
This has bugged me for a bit. First question is how to keep classes with
rbind, and second question is how to properly return vecotrs instead of
lists after turning an rbind of lists into a data.frame
list1=list(a=2, b=as.Date("20090102", format="%Y%m%d"))
list2=list(a=2, b=as.Date("20090102", format="%Y%m%d"))
rbind(list1, list2) #this loses the

dramatic speed difference in lapply
So I have a function that does lapply's for me based on dimension. Currently
only works for length(pivotColumns)=2 because I haven't fixed the rbinds. I
have two versions. One runs WAYYY faster than the other. And I'm not sure
why.
Fast Version:
fedb.ddplyWrapper2Fast <- function(data, pivotColumns, listNameFunctions,
...){

Although my doubt is pretty,as i m not from stats background i am not sure
how to proceed on this.
Currently i am doing a forecasting.I used ARIMA to forecast and time series
was volatile i used garchFit for residuals.
How to use the output of Garch to correct the forecasted values from ARIMA.
Here is my code:
###delta is the data
fit<-arima(delta,order=c(2,,0,1))
fit.res <-
