[R] Print to File Formatting

[Brigid Mooney]

Hello,

I am writing out to a file and have two quick questions that I can't
seem to track down the correct answers for.  Luckily, I *think* they
are both simple enough that someone might be able to point me in the
right direction on them without too much trouble.

Both questions relate to the process below where CompleteFrame is a
data frame containing what I want printed to a file.

filename <- "C:\\MyDocuments\\TestOut_050609.txt"

output <-file(filename, open="wt")
write.csv(CompleteFrame, output, row.names = FALSE, col.names=FALSE)
close(output)

Question #1:
Every time I run this process, I get the warning:
Warning message:
In write.csv(CompleteFrame, output, row.names = FALSE, col.names = FALSE) :
  attempt to set 'col.names' ignored

And it still prints the column names as the first row in my file,
which I do not want...

Question #2:
This process puts quotes around all data of class = character.
I can't have these quotes in my file - is it possible to get R to omit
them even if my data frame contains character strings?


Any help or hints on this are greatly appreciated!

Thanks,
Brigid
