- haddr 7y agoOriginal article doesn't say anything about "database join". It's about joining two datasets by some common ID. R in this case fits the bill and even allows for some relational algebra here (e.g. INNER JOIN would be merge(X, Y, all=FALSE), LEFT OUTER JOIN: merge(X, Y, all.x=TRUE), etc...)
- stilisstuk 7y agoMerge joins the two dataset on identical columns. All=True is an outer join.
