[R] Please help me to combine two datasets.

[Sean O'Riordain]

merge(data.set.1, data.set.2)

but how do I know which rows to drop in ds1?

if data.set.2 had dates, you could say

merge(data.set.1, data.set.2, by.x=Date, by.y=Date, all=T)

or do you just want to drop the first
length(data.set.1)-length(data.set.2) from data.set.1?

do you have NA values?

cheers,
Sean
