Hello John
Thank you for the tips
I already tried by using RKWard and RStudio and I got the same error...so
I
passed to the R console
Maybe it's the buffer limit but, since I'm really newbie to R, I'ld like
to
know how to configure this limit
In any case in my application I'ld like to avoid to write data in a csv
file (by using java) and then use R in order to import these data....I'ld
like to read data from DB and then pass them to R (well it'ld be good
also
if R read data from DB...but I'm afraid I can do a great mistake in
handling connection and so on in R and my time is really short)
Is there any way in order to read data from db (in Java) and pass all the
data to R without write them in a csv file?

Thank you to all you
Cheers,
Angelo

I am currently getting the very strange results that if I paste your
orginal data from your first message into my R terminal I get the same
errors you do. By the way that ";" is not needed in R.

If I paste the same data into Rstudo, either into the editor or the
console it works fine.

If I paste the data into gedit and send it to the console it works fine
but if I paste it into the gedita console I get your error messages
again.
A quick try, pasting it into an R buffer in EMACS seems to work just
fine.

I have no idea what is happening unless jagat.k.sheth is correct and we
are hitting a buffer limit of some kind.

I'd suggest getting a decent editor and going with it.  Working directly
in an R terminal is enough to drive most people crazy.

Any of the editiors/ides mentioned above are good with different
strengtsts etc.  At a guess, Rstudio is the easiest to install and get
running on Ubuntu, gedit is pretty easy but you need to install the r
gedit
plug-in. EMACS as far as I can tell is very good and very powerful but I
have not used it enough to really comment on it.

In any case one way or the other they can read in the data.  I'd also
suggest not even 'thinking' about writing a vector statement that long.
It
would be much easier to do something like write the numbers in a column
in
a spreadsheet and import from there. There are various ways to do this
but
the simplist would be to just save the file as a csv file and import it
using read.table or read.csv.

I'm  sorry that I cannot be of more help. Perhaps one of the R gurus can
comment on the possible buffer problem.

Hello John
It seems correct to me too but in my R console it seems to not be

working

Here there is what I did:
i copied the statement on one row (leaving and removing the final

useless

semi colomn)
i tried to execute it in the R console (in order to open my R console I
simply opened a terminal window on my ubuntu machine and I typed "R")
when I click "enter" the inserted statement doesn't not run...I simply
see
the cursor on a new line and this new line starts with "+"

Here there is a little stack of what I see on my terminal:
, 1, 1, 2, 2, 0, 3, 0, 0, 0, 0, 0, 0, 0, 0, 1, 0, 0, 0, 0, 1, 17, 2, 2,

+
+
+
+
+

Each time i click enter i go on a new line starting with "+"
Then if i start in tying some character I get an error like this:

+
+
+ q
+
+ q
Errore: unexpected symbol in:
"
q"

Sometimes this error (Errore: unexpected symbol in:) appears in the
statement execution

Here there are my sessionInfo() result:

sessionInfo()

R version 2.14.1 (2011-12-22)
Platform: i686-pc-linux-gnu (32-bit)

[11] LC_MEASUREMENT=it_IT.UTF-8 LC_IDENTIFICATION=C

attached base packages:
[1] stats     graphics  grDevices utils     datasets  methods   base


I really don't know why this happens....above all because it seems to
me
a
very very simple statement...
Thank to all you for the support
