Overview of Date-Time Handling in R

These materials were prepared for a meeting of the East Bay R Beginners Meetup Group in Oakland on 2-Oct-2018.

To build the main presentation using RStudio:

• Open the "time-2018-10.Rproj" project file with RStudio
• Confirm you have/install all of the requisite packages from CRAN (install.packages or use the Packages pane):
  • dplyr
  • ggplot2
  • lubridate
  • knitr
  • DiagrammeR
  • rmarkdown
• Use the Console pane to type in the command

setwd( "presentation" )

(or other appropriate directory)

• Then use the "Files" pane to click on the "presentation" directory,
• then click on the "DateTimeHowto.Rmd" file in the "Files" pane to open it,
• Then click the "knit" button at the top of the Editor pane with the "DateTimeHowto.Rmd".

To build the main presentation using only the R console:

• Start R
• Set the working directory to the "presentation" directory. Your R program may have a menu item for this, or you can use the setwd() function.
• Run the command:

  rmarkdown::render( "DateTimeHowto.Rmd" )
  

  • Optionally you may need to install the rmarkdown package from CRAN if you have not already done so:

  install.packages( "rmarkdown" )
  

Too much work?

You can open the Rmarkdown files and read them directly... they are plain text files.
