I am trying to practice creating some PowerPoint presentations with RMarkdown using RStudio. I have a fairly large dataframe from which to create a ggplot object. I have to create the large data frame first, and then isolate the pieces I need to create the chart (via a variety of maipulations) till I get the data tidy, etc.
- Do I always need to do all of this within the R Markdown environment? i.e., if he data exists in my Global Environment, it still seems like i need to create it in the R Markdown document as well (or I receive an error.) It seems like this is the case based in what I am seeing in my online searching....
- Performing the manipulations on a large data frame seems to be particularly slow in the R Markdown session - is this typical?
- Lastly, does anyone know of a PowerPoint Template in R Markdown that creates a 4-Blocker on one slide? For example, I want to create a slide with 4 bar charts (each of equal size and presented nicely on the slide.)
