Madams & Sirs,
  I use write.table to write CSV files to generate reports for my colleagues to 
open in their spreadsheet application of choice.  I often append data of 
dissimilar structure to the same file, i.e. a few summary lines and then 
additional data of some number of columns.

Normally write.table produces:
> write.table(etest[,writevars],file=fname,row.names=FALSE,col.names=TRUE,
        append=TRUE,sep=",")
Warning message:
appending column names to file in: write.table(etest[, writevars], file = 
fname, row.names = FALSE,  


Therefore I resort to:

> options(warn=-1)
> write.table(etest[,writevars],file=fname,row.names=FALSE,col.names=TRUE,append=TRUE,sep=",")
> options(warn=0)


However I thought that perhaps a parameter such as included for dir.create 
would be more elegant:
> write.table(etest[,writevars],file=fname,row.names=FALSE,col.names=TRUE,
        append=TRUE,sep=",",showWarnings=FALSE)


where showWarnings would default to TRUE.
