[BioC] Question about topTable output formatting (Limma) in Excel

[J.delasHeras at ed.ac.uk]

When I use the topTable function to create a table with my data, like this:

toptableH226<-topTable(ebws, coef=1, n=number, genelist=gal, 
adjust.method="BH", sort.by="B")

and then I write it to a file with write.table, like this:

write.table(toptableH226, "180406-toptableH226.txt", sep="\t")

this produces a tab-delimited text file with my data, perfect.

However, if I open the file in Excel, the first row seems off by one 
column, and I have to insert an empty cell in A1, displacing the first 
row to the right, so that the headers match the columns. Why is this? 
If I retrieve elements from the topTable output they seem okay.

The first column of the output contains numbers specifying the row 
locations of the genes. There is no header for that column. So the 
first row has one less element than the others.

It's not a big deal, but...

is there some parameters I should be specifying that I don't? I haven't 
found anything obvious.

Thanks!

Jose
