Here's another solution, similar to the ones above, which aims to be straightforward:
zz <- cbind(name=f[1],year=rep(min(f[-1]):max(f[-1]),each=nrow(f)))
zz$indicator <- as.numeric((f$name==zz$name &
f$year.start<=zz$year &
f$year.end >=zz$year))
result <- zz[order(zz$name,zz$year),]
The first line builds a template with all the names and all the years. The second line sets indicator
based on whether it is present in the range. The third line just reorders the result.
