How can I extract part of the data in a panel dataset?
Taking the Grunfeld data, which is built-in in R, for example,
(1)How can I construct a dataset (or dataframe) that consists of the data
of all firms in 1951?
(2)How can I calculate the average capital in each form over the period
1951-1954?
What I can imagine is to categorize the data by firm, and then select the
data between 1951 and 1954 for each firm, but how can I do it?
Thanks,
Miao
