Hi Daniel,
You did not make clear why you want to export the data. If you want to
export data to another program the usual way to export data to a text
file is through the use of write.table(). Something along the lines of:
summary(cars) # cars is a standard R dataset
write.table(summary(cars), file = "dataexp.txt")
?write.table
If you want to store R data to read it back into R again I would
recommend the save() option in combination with the load option. Example:
x = summary(cars)
save(x, file = "dataexp.rda") # The extension of the file is not
really
important
# Load a new R session
load("dataexp.rda") # This makes the object "x" available in
the new session
cheers,
Paul
