Hello again,
Try changing the lines where you create 'EMUmix3' and 'EMUmix4' by the
following.
EMUmix3 <- Reduce(`&`, lapply(countries, function(x,y){country1 %in% euro2 &
!country2 %in% euro2}))
# euro2 are also the EMUcountries, BUT in 2001 Greece became a EMU member.
So in the interval (1999:2000)
# all euro countries are represented and from 2001- all euro+GREECE=euro2
are represented.
EMUmix4 <- Reduce(`&`, lapply(countries, function(x,y){!country1 %in% euro2
& country2 %in% euro2}))
The problem is that Greece is part of 'noneuro', like this you negate
'country* %in% euro2'.
See if it works, I'm not sure.
