Hi Alexander,
from the Help page of write:
Usage
write(x, file = "data",
ncolumns = if(is.character(x)) 1 else 5,
append = FALSE, sep = " ")
Arguments
x the data to be written out.
file A connection, or a character string naming the file to write to. If
"", print to the standard output connection.
ncolumns the number of columns to write the data in.
append if TRUE the data x are appended to the connection.
sep a string used to separate columns. Using sep = "\t" gives tab
delimited output; default is " ".
So, set ncolumns to 1 for a one-column file. No bug AFAIKS.
Regards,
Hilmar

It is the same with any sep.I don't see a bug. This is pretty clearly behaving as documented. By default, it sets ncolumns to 5 for non-character data. If you want it all on one line, set ncolumns to length(array). Duncan Murdoch
First of all, it's not a bug. Please don't report bugs before
bringing up the "issue" on r-devel. FYI, there are people (not me),
who have to go through all bug reports, tag them, and clean them out
manually.
If you do print(write), your concerns are answered:
function (x, file = "data", ncolumns = if (is.character(x)) 1 else 5,
append = FALSE, sep = " ")
cat(x, file = file, sep = c(rep.int(sep, ncolumns - 1), "\n"),
append = append)
<environment: namespace:base>
You could also have inferred that from reading help(write).
Now, why there is this default rule for writing non-character values
in 5 columns I don't know. There must be a historical reason for this
design.
Cheers
