We will focus on the data.table package and it's modifications from dataframes which most of you will have seen before.\r\n\r\nIf we have time I'll compare it to other approaches: dataframes, matrices, bigmemory, RMySQL and do some benchmarking on speed. This format works a bit differently to what most of R does but it's got some cool features, including fast reading data files into R, and is compatible with most functions (including Hadley's packages) using dataframes.\r\n\r\nYou're welcome to follow along, I'll be using using the gapminder dataset from Software Carpentry workshows. I'll post a link to the data closer to the time.\r\n\r\nWe're also discussing bringing back the 5x5 Lightning format in a couple of weeks, it's a great opportunity to have a go at SYSKA if any of our newest study-group-ers want to have a go at one. Let us know! :)"},"comment":{"url":"https://api.github.com/repos/OtagoStudyGroup/studyGroup/issues/comments/207132357","html_url":"https://github.com/OtagoStudyGroup/studyGroup/issues/21#issuecomment-207132357","issue_url":"https://api.github.com/repos/OtagoStudyGroup/studyGroup/issues/21","id":207132357,"user":{"login":"TomKellyGenetics","id":5493325,"avatar_url":"https://avatars.githubusercontent.com/u/5493325?v=3","gravatar_id":"","url":"https://api.github.com/users/TomKellyGenetics","html_url":"https://github.com/TomKellyGenetics","followers_url":"https://api.github.com/users/TomKellyGenetics/followers","following_url":"https://api.github.com/users/TomKellyGenetics/following{/other_user}","gists_url":"https://api.github.com/users/TomKellyGenetics/gists{/gist_id}","starred_url":"https://api.github.com/users/TomKellyGenetics/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/TomKellyGenetics/subscriptions","organizations_url":"https://api.github.com/users/TomKellyGenetics/orgs","repos_url":"https://api.github.com/users/TomKellyGenetics/repos","events_url":"https://api.github.com/users/TomKellyGenetics/events{/privacy}","received_events_url":"https://api.github.com/users/TomKellyGenetics/received_events","type":"User","site_admin":false},"created_at":"2016-04-07T23:07:37Z","updated_at":"2016-04-07T23:07:37Z","body":"Sorry, to mess with our regular time. I've got a demonstrators meeting at 4 so (if possible) I'd like to start half an hour earlier than usual. I'll have to leave at 4 but you're welcome to continue discussion, tinkering with data.table, or \"hackyhour\" type questions about code.\r\n\r\nAs usual you are welcome to bring your laptops to follow along and try things out for yourself. We'll be using a few R packages on CRAN, I think most of are set up with R/RStudio installed and access to the university/eduroam network but we can help with this on the day too."}}
