My aim is to create a table that summarizes the countries featured in my sample. This table should only have two rows, a first row with different columns for each region and a second row with country names that are located in the respective region.

To give you an example, this is what my `data.frame` `XYZ` looks like:

```
..................wvs5red2.s003names.....wvs5red2.regiondummies
21............."Hong Kong"......................Asian Tigers
45............."South Korea"....................Asian Tigers
49............."Taiwan".............................Asian Tigers
66............."China"...............................East Asia & Pacific
80............."Indonesia"........................East Asia & Pacific
86............."Malaysia"...........................East Asia & Pacific 

```

My aim is to obtain a table that looks similar to this:

```
region.............Asian Tigers..............................................East Asia & Pacific
countries........Hong Kong, South Korea, Taiwan...........China, Indonesia, etc.

```

Do you have any idea how to obtain such a table? It took me hours searching for something similar.
