[R] Is there anything like a write.fwf() or possibility to print a data.frame without rownames?

[Gregor Gorjanc]

Dear R users,

R has read.fwf() function, however I would need write.fwf. I know other
write.* functions, but I need fixed width format of data, which I would
like to export from R. I tried to use:

- write.table, but I can not control alignment of columns

- write.matrix from MASS, but columns are to wide

I came to this option, which is very neat:

# tmp is data.frame

sink(file = file)
print(tmp)
sink()

This works very nice, but I would like to get rid of rownames, which
are always printed.

Another not so important issue is width of printed columns. I presume
this is determined by max(length column name, max(length of "values" in
a column)) but sometimes it would be usefull to control width of columns
also.

Can someone help me with this issue?
