Dear all,
I was working on number of files and at the end I got a data
frame with approx. million rows.To prin this data frame in
output, I used
capture.output(print.data.frame(end,row.names=F), file =
"summary", append = FALSE)
where end is the name of my data frame and summary is the name
of my output file.
but when I checked the output there were only 10000 rows and at
the last it was written-
[ reached getOption("max.print") -- omitted 923750 rows ]]
Can you please tell me what is wrong with my output code?
Nothing.
I want to print all million rows in my output.
I'm trying to figure out why, after that warning message, you did
not immediately pull up the help page for getOption?
Perhaps he was looking for a way to override the option rather
than change it?
print(...., max=2e6)
should do the trick. (Documented on help(print.default), which
perhaps _is_ a little hard to find your way to.)
You mean that options(max.print=2e6) wouldn't have done the same
thing? That was what I thought would work when I looked at
help(getOption). Seemed to work just fine when I just tested it.
It does, but next time he does something to the million-row data
frame, and forgets to assign the result, he'll see a million lines
whizzing by in his console. Unless he remembers to do
old <- options(max.print=2e6)
print(....)
options(old)
I thought the implications of the option change were obvious, as well
as the way to set it back to a smaller number. In addition that change
would only have lasted during the current session and would revert to
the default with the next session. It's not like I told him to change
it in his .Rprofile after all.
