So, dtplyr provides the best of both worlds. My top 10 Python packages for data science. If you were working with a heavy workload with a need for distributed cluster computing, then sparklyr could be a good full stack solution, with integrations for Spark-SQL, and machine learning models xgboost, tensorflow and h2o. USGS-R Packages. If it runs with SQL, dplyr probably has a backend through dbplyr. Running low on disk space once, I asked my senior actuarial analyst to do some benchmarking of different data storage formats: the “Parquet” format beat out sqlite, hdf5 and plain CSV – the latter by a wide margin. A few months ago, Zeming Yu wrote My top 10 Python packages for data science. However, installation in R remains tricky as at time of writing and involves downloading Rtools, Git for Windows, CMake, VS Build Tools and running the following: If that looks too hard, that is why I would still recommend xgboost for R users at the present time. We have taken a journey with ten amazing packages covering the full data analysis cycle, from data preparation, with a few solutions for managing “medium” data, then to models - with crowd favourites for gradient boosting and neural network prediction, and finally to actioning business change - through dashboard and explanatory visualisations - and most of the runners up too… I would recommend exploring the resources in the many links as well, there is a lot of content that I have found to be quite informative. Interactivity similar to Excel slicers or VBA-enabled dropdowns can be added to R Markdown documents using Shiny. Let me know in the comments! It does require some additional planning with respect to data chunks, but maintains a familiar syntax – check out the examples on the page. There has been a perception that R is slow, but with packages like data.table, R has the fastest data extraction and transformation package in the West. To do so, add ‘runtime: shiny’ to the header section of the R Markdown document. It’s a tool for doing the computation and number-crunching that set the stage for statistical analysis and decision-making. For another example of keras usage, the Swiss “Actuarial Data Science” Tutorial includes another example with paper and code. There has been a perception that R is slow, but with packages like … To action insights from modelling analysis generally involves some kind of report or presentation. R packages are a collection of R functions, complied code and sample data. A package is a collection of R functions, data, and compiled code in a well-defined format. If you want to get up and running quickly, and are okay to work with just GLM, GBM and dense neural networks and prefer an all-in-one solution, h2o.ai works well.
