R help - Jun 2006 - saving rounded numbers as a new variable in a dataframe

A basic question, but one that eludes me. I have created a new variable 
$numurder, which I have rounded off. I want to save the rounded off version 
of this variable to an existing datafile called 'ngri.csv' .

  numurder   <-c((murder*no.of.cases)/100)
[[1]]
  [1]  48.952 112.073 182.160 974.610 122.140 663.432 150.856  18.988 
137.925 198.045  68.930 203.148  30.056 100.955


round(numurder, 0)
  [1]  49 112 182 975 122 663 151  19 138 198  69 203  30 101


Advice regarding how to do this is appreciated,

Bob

Hi

1-Please read this: R Data Import/Export 
cran.r-project.org/doc/manuals/R-data.pdf
2-This is the code:

rounded <-round(numurder, 0)
write.csv(rounded,"c:/ngri.csv")

this will erase former ngri.csv and write a new ngri.csv containing 
only rounded variable!!!

Let ngri is data frame from which you have murder and other variables

then

write.csv(data.frame(nmurder=rounded, ngri),"c:/ngri.csv")

shall be better choice.
