About Waffle Bar Charts with scales

Hi,I 'm a new beginner of R. I want to use "waffle bar chart with scales" to show my data, but I met some problems.
This is a data example I want to show. I want to classified by cause_id, and the value is "us" displayed in data to show by just waffle bar charts with scales.
This is an example code

example<-structure(list(year = c(1990L, 1990L, 1990L, 1990L, 1990L, 1990L,

I'm not sure can this type of data be showed by waffle bar chart?
Because when I write the first row coding

global_2c <-example %>%
            dplyr::count(year,cause_id)

and my data frame will be showed like this


because the number of cause_id in every year is equal.I'm so curious about that this situation can use waffle?

This is the waffle package 's details :Issues · hrbrmstr/waffle · GitHub

I think we need a FAQ: How to do a minimal reproducible example ( reprex ) for beginners

A handy way to supply some sample data is the dput() function. In the case of a large dataset something like dput(head(mydata, 100)) should supply the data we need.

Hi,I modified my question according your suggesstion. Thank you so much.

Thank you, this really helps. I do not have time today to look at the problem but I am sure more expert people will be able to help. If not, I'll look at it tomorrow but we can hope that someone with real expertise looks at it before me.

Thank you so much for your reply!

I am horrible embarrassed. I ran into some moving problems and only today got back to RStudio and your problem.

The only way I can see to do it would be to do a series of charts and then use something like the plot_grid function in the coplot package or the iron function in the waffle package.

I had thought I could geom_waffle but I keep getting an error

Error in geom_waffle(n_rows = 8, size = 0.33, colour = "white") : 
  could not find function "geom_waffle"
