Positron IDE doing Data Analysis with R (Public Beta)

Timeline 00:00 Intro 00:25 Select R as the interpreter from the upper right corner. 00:40 View the usual R startup message in the lower-left window. 00:50 Discussion on keyboard shortcuts. 02:00 Enable RStudio keyboard shortcut mapping in Positron. 02:47 Create a new R Project in Positron for data analysis. 04:10 Discuss setting the working directory correctly in the R Project. 05:02 Save R Script using CMD + S or CTRL + S. 05:45 Mouse over a file to see its file system path. 06:02 Close the explorer bar for maximum screen space. 06:45 Start coding in an R Script. 07:47 Use CMD + ENTER or CTRL + ENTER to send code from the R script to the console. 09:04 Mouse over URLs and hold CMD or CTRL to make them clickable. 10:00 Discuss session and variables holding code results. 10:42 Observe downloaded data in the R project directory using the file explorer. 11:30 Explore what a Data Frame looks like under the session's Data subheader. 12:00 Trigger the interactive data explorer. 12:27 Identify variable types (pound sign (#) for numbers, (A) for strings/factors). 13:50 Sort data within the interactive data viewer. 15:00 Apply a filter to the data. 16:00 Hide/clear filters. 16:31 Expand the right-hand side to see additional text like variable type and number of observations. 19:00 Modify the dataframe to include a new derived variable that is a factor. 19:40 Open the Data Viewer using the View() function. 20:55 Handle an error with a missing package. 22:36 Graph with ggplot2. 24:35 Explore the plot area of Positron. 26:57 Demonstrate Plotly with ggplot2. 28:31 Count with dplyr. 29:03 Use the pipe operator shortcut (CMD + SHIFT + M or CTRL + SHIFT + M). 30:21 Create a gt() table with the count data. 31:07 Explore help documentation with Positron. 31:38 Run examples to execute static examples within the help window. 31:58 Handle a hiccup when viewing the package's index HTML page. 32:06 Final thoughts. Summary --- For this video, we take a look at the Positron IDE's R session features. We focus on using an R project and a single R script file. We explore different portions of the interface, including the famed interactive data viewer. This video covers a large gambit from setting up keyboard shortcuts similar to what is available in RStudio to creating interactive plots using the {plotly} package.
