Writing to a file in R prints on 2 lines

Question

I am writing a vector to a file in R. However the output comes on 2 lines. I wanted all the values to come on a single line. Can you let me know how to fix this

write(value,file=fileconn,append=TRUE,sep="\t")

The o/p comes as follows

1777.167 1825.167 1873.167 1921.167 1969.167

2017.167

That's what I was going to suggest too cat(value, file = "filename") might be better. And then you can use scan to read it back in. I'm also curious to know what fileconn is. Is that a connection? — Rich Scriven

@Mr.Flick Thanks. I did not realize that write had a ncolumns parameter. I did check on other vectors and I did notice that it defaulted to 5 columns. I added ncolumns and it is fine write(value,file=fileconn,append=TRUE,sep="\t",ncolumns=7) — Tinniam V. Ganesh

@Richard the file columns is a connection fileconn <-file(filename) — Tinniam V. Ganesh

I'm not sure write() is probably not the best choice, but if you want to use it, it might be a good idea to check the ?write help file. It does have an ncolumns= parameter which defaults to 5 for simple numeric vectors.

I would think cat() would be a better solution for just dumping numeric vectors.
