longitudinal data
Hello all,
I want to analyze data that looks like this:
Id var1 var2 var3..
1 0 1 0
1 0 1 1
2
2
2
2
Not all id's have the same no. of observations.
At the first stage I want to count how many people in the survey, how many
have 1 in var1, etc.
How do I do that?
Thank you,
Sigalit.

table function
Hello all,
I want to use the "table" function, but for every id I have a different no.
of rows (obs.).
If I write:
table(x$class, x$infec)
I don't get the right frequencies because I should count every id once, if
id 1 has 20 observations It should count as one.
can I use unique func. here?
Hope it's clear.
thank you,
Sigalit.
