class: split-40 count: false shows in slides and slides don't behave as expected

[novica]

Again, I am not sure if this is an issue or I am just not using the templates properly.

When I try to make a plot with the latest tidy tuesday data I get this in the slides:

I am recreating your slow ggplot example and the code chunk that should show in the above slide looks like this

ggplot(data = park_visits_grouped) +
  aes(x = year) +
  labs(x = "the x label") +
  aes(y = visitors_per_year) +
  labs(y = "the y label") +
  scale_x_continuous() +
  geom_line() +
  geom_area(alpha=.3) +
  labs(col = "legend title") +
  labs(title = "My title") +
  theme_minimal()

r apply_reveal("national_parks_visitors")

What happens for me is I get the plot image first and then the code is below. Then I go to the next slide and it recreates the whole thing. I'm not sure if I am explaining this well.

I am using r 3.6.1-1 and rstudio 1.2.

I think you need to add a '---' slide separator between your code chunk and apply_reveal() in line. Does that make sense? But, if you set the code chunk to eval = F you won't need the the slide separator. Also, be careful that you don't have any trailing spaces after the '---' because Xaringan won't interpret that as a separator if there is. Please let me know if this works.

I was trying to follow the same code that was in the template but maybe I copied something wrong. I will try again for sure, but I got frustrated because it seems the Rstudio editor is behaving strangely when I am trying to do the slides.

I don't even know how to explain, but when typing whatever in the code chunk area it seems some of the text gets misplaced and then the .Rmd crashes.

By misplaced I mean I have a code chunk such as:

ggplot(data = my_data) +
  aes(x = var1) +
  labs(x = "the x label") +
  aes(y = var2) +
  labs(y = "the y label") +
  geom_point() +
  aes(col = var3) +
  labs(col = "legend title") +
  labs(title = "My title")

and want to change for example aes(x = var1) to aes(x = var3) and I type that but end up with a line that looks like aes(x = var1)3. And I am pretty sure I am typing correctly and nothing strange is going on with my keyboard.

This hasn't happened to me in any other .Rmd so far, and I don't know how to deal with this issue; wether it is a bug in Rstudio or something with Xaringan and the flipbook setup.

I'd probably take a break, like you are doing, and restart RStudio when you are ready to come back to it. It sounds like a buggy RStudio issue as it is happening in editing the .Rmd. Good luck!

Thanks for reporting on how it's going.

The file has been modified so that it has the cars data as an example instead of gapminder. Thanks for the feedback.

Awesome. Thank you @EvaMaeRey
