Hi all,

I am using tess3r package to plot bar plots of the Q matrix of ancestry coefficients that I got from sNMF analysis.

But I am interested to order the matrix based on counties first and then based on Q, in another word, I want to have the matrix ordered by countires and within the conuty ordered by Q.

For example this is a q matrix, I've added the county for each individuals

```
1.00E-04 0.75453 1.00E-04 0.24507 1.00E-04 1.00E-04 CM04487 Benin

```

in tess3r package running this part won't give what I want, because it sorts based on Q only.

```
barplot(Q.matrix, sort.by.Q = FALSE,
border = NA, space = 0,
col.palette = my.palette,
xlab = "Individuals", ylab = "Ancestry coefficients") -> bp
```

Guid and help is much appriciated.

Thanks!
