I guess you can use na.string=1st missing value
then data[data==second missing value]-NA.

For some reason I get a file with negative numbers formatted with negative sign

Closer, but be aware that all.equal will not always return TRUE or FALSE and -
more importantly - as.integer truncates towards zero and does NOT generally
round to the nearest integer.

Dear Rers,
I am trying to run a for-loop in R.
During each iteration I read in an mp3 file and do some basic processing.
If I do what I need to do for each file one by one - it works fine.
But once I start running a loop, it soon runs out of memory and says: can't
allocate a vector of size...

You don't say what processing you are doing.. the answer to your question is
very likely there. To communicate effectively on this mailing list,
self-contained examples are needed. And in order to not corrupt the example you
will need to post in plain text.
Jeff,
here is what I do with each file using library(tuneR):
b-readMP3(cairnomount.mp3)
myrange-range(b@left)
write.table(myrange,x myrange.txt,sep=\t)
Would you like me to attach a bunch of large mp3 files?
I don't feel I have the right to clog people's inboxes with large files.
Thanks!

It is your responsibility (not mine) to simplify your example to the point

There is currently no way to write your own unary operator in R. The

major changes to the parser to recognize the syntax that you want

Hi
I think the problem is that, as David Carlson pointed out, ellipses()
works by redrawing the plot and adding more to it.
This means that your PDF version has *two pages*, one with the original
plot, then another with the plot-plus-ellipses.
