Dear all,
I'm newbie with R (changing from STATA), and I can't find some commands.
One of those is the "combine", which I use to combine means like this:
--------------------------------------------
n1 m1 sd1 n2 m2 sd2
combine 12 3 1 34 45 4
Combine has calculated the following values:
combined n = 46
combined mean = 34.043478
combined SD = 18.964829
--------------------------------------------
Does anybody knows a simmilar command in R to combine means?
Thanks in advance.
Carlos.
