When one has raw data it is easy to create a table of one variable against
another and then calculate proportions
For example
a.nice.table<-table(a,b)
prop.table(a.nice.table,1)
However, I looked at several papers and created a data frame of the
aggregate data. That means I acually created a table except it is a data
frame. The first column lists the name of the first author and the year.
I cannot find how to convert the data frame to a table so I can use great
functions such as prop.table and margin.table.
Alas I tried, rowSums but it provides lousy output without listing the names
of th papers.
I have thought of going through the reshape package but I suspect that there
is an easier way to convert a data frame to a table. Is there?
