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).

      > system("C:/upload_data/uploadq8.bat
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:

      > 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!
