I am running R version 2.8.1 on Windows XP OS.
I generate and write a .csv file from my R script. Then the following
command works to upload it to a remote server using a windows batch file
that carries out the ftp (among other things).

C:/upload_data/out_2009-02-26.csv", wait=FALSE)
I want to set this up to run daily and create a unique filename each day it
runs. I write the .csv file with a unique filename by
> fname <- paste("out_",Sys.Date(),".csv",sep="")
> write.table(config_all5,file=fname,row.names=FALSE,
quote=FALSE,sep=",");
I can build the string (including quotes) that is the first argument in
the system command:
Don't include the quotes.
> com <- paste('"C:/upload_data/uploadq8table.bat
C:/upload_data/',fname,'"', sep="")
Should be
com <- paste('C:/upload_data/uploadq8table.bat
C:/upload_data/',fname, sep="")

> com
[1] "\"C:/upload_data/uploadq8table.bat
C:/upload_data/out_2009-02-26.csv\"",
But when I substitute it into the system command I get an error:
> system(com, wait=FALSE)
Warning in system(com, wait = FALSE) :
"C:/upload_data/uploadq8table.bat C:/upload_data/out_2009-02-26.csv"
not found

Any suggestions for how to resolve are appreciated!
