Hello,

I have a file -

```
GeneID      sample1          sample2        sample3        sample4        gene_length
gene1       count1           count2         count3         count4         length1
gene2       count1           count2         count3         count4         length2
gene3       count1           count2         count3         count4         length3
gene4       count1           count2         count3         count4         length4
```

When imported to R using `read.table()` I get columns assigned by default as V1, V2, V3 etc, but how can I set the first row as the column names?

    GeneID    sample1    sample2    sample3    sample4    gene_length

Thanks
Add Argument `header=TRUE`
