Should we use this Issue to collect some things?\r\n\r\n- in place mutation of columns simply works with built-in `map!` which is so much better, than the weird `data.table` syntax, \r\n- `stack`/`unstack` is performant and works great and mostly as in R.\r\n- `filter` is much better than creating extra index vectors. At some point someone should probably create a cheat sheet for R users."},"comment":{"url":"https://api.github.com/repos/JuliaData/DataFrames.jl/issues/comments/423779749","html_url":"https://github.com/JuliaData/DataFrames.jl/issues/1530#issuecomment-423779749","issue_url":"https://api.github.com/repos/JuliaData/DataFrames.jl/issues/1530","id":423779749,"node_id":"MDEyOklzc3VlQ29tbWVudDQyMzc3OTc0OQ==","user":{"login":"ararslan","id":6396159,"node_id":"MDQ6VXNlcjYzOTYxNTk=","avatar_url":"https://avatars1.githubusercontent.com/u/6396159?v=4","gravatar_id":"","url":"https://api.github.com/users/ararslan","html_url":"https://github.com/ararslan","followers_url":"https://api.github.com/users/ararslan/followers","following_url":"https://api.github.com/users/ararslan/following{/other_user}","gists_url":"https://api.github.com/users/ararslan/gists{/gist_id}","starred_url":"https://api.github.com/users/ararslan/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/ararslan/subscriptions","organizations_url":"https://api.github.com/users/ararslan/orgs","repos_url":"https://api.github.com/users/ararslan/repos","events_url":"https://api.github.com/users/ararslan/events{/privacy}","received_events_url":"https://api.github.com/users/ararslan/received_events","type":"User","site_admin":false},"created_at":"2018-09-22T23:09:49Z","updated_at":"2018-09-22T23:09:49Z","author_association":"MEMBER","body":"I believe such a thing exists somewhere, but I can't recall who it was who made it. @piever maybe?"}}
