Hi Nick,
I will def. need the tab command later. Thanks.

What I meant was like this:
In the example below, 3 countries are covered by the variable x1.
When I run a regression (xtreg) with x1, that will give me the number
for countrynumber.
But I was wondering if there's a command like 'tab' which will give me
the count.

countryno	x1
1	0.55
1	0.55
1	0.55
	0.55
.	0.55
.	0.55
2	0.55
2	0.55
2	0.55
2	0.55
.	3.31
.	3.87
.	4.42
.	4.97
.	5.52
	6.08
.	6.63
3	7.18
3	7.73
3	8.29
