Hey everyone,

I am looking for the easiest way to get this table

# Table2
Year / 2000 / 2002 / 2004
Julia / 3 / 4 / 1
Peter / 1 / 2 / 4
...   /   ...   /   ...   /   ...

out of this one? 

# Table1
name   /   year   /   cases
Julia   /   2000   /   1
Julia   /   2000   /   2  
Julia   /   2002   /   4
Peter   /   2000   /   1
Julia   /   2004   /   1
Peter   /   2004   /   2
Peter   /   2002   /   2
Peter   /   2004   /   2
...   /   ...   /   ...

Code for table1:
name <- c('Julia','Julia','Julia','Peter','Julia','Peter','Peter','Peter')
year <- c(2000,2000,2002,2000,2004,2004,2002,2004)
cases <- c(1,2,4,1,1,2,2,2)
table1 <- data.frame(name,year,cases)

Thanks! Dominik
