[R] Outputting csv file from dataframe with columns in a particular order

[Ivan Calandra]

Hi!

Let's say your data.frame is called df and that you want column 1, then 
column 4, then 3 and then 2:
df <- data.frame(ID=LETTERS[1:5], date=rnorm(5), estimate=rnorm(5), 
actual=rnorm(5))
write.csv(df[c(1,4,3,2)], file="df.csv")

HTH,
Ivan
