[R] write.table when keeping column headers (names of Columns in matrix) and row numbers

[Peter Wilkinson]

When using the write.table (say for a tab delimited file) command on a 
matrix with Row and Columns, the column headers are always being left 
shifted into the column where the row numbers are being placed. One can see 
this when you open up the tab delimited file in excel.

Is there a better command for this, or is this supposed to be a 'feature'.
