[R] R strange behaviour when building huge concatenation

[John Kane]

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.
