How to make the mosaic plots of 20 dataframes and put them in one page in r?

Question

I created 20 data frames in a loop already. And assigned them in the loop as below

for(x in 1:20){
  my_file <- read.table(paste0("file_name",x), head=TRUE) %>% 
    select(Count, Total) %>% 
    data.frame()
  assign(paste0("my_file_",x), my_file)
}

And I get each data frame just like this: (each data frame has the same Count names with the same sequence but the numbers are different)

Count  Total
 A      22
 B      31
 C      45
 D      70

How can I make the mosaic plot for each data frame and put them on one page , with the same arrangement as below?

Block A  Block B
Block C  Block D

Thank you so much for your help!

The details depend on the particular package/function you are using. If you use the base mosaicplot() function, you can simply employ par(mfrow = c(..., ...)) with a suitable layout. If you are using mosaic() from vcd then you can either create your own viewport() with a grid.layout() or use the mplot() function for that purpose. See example("Ord_plot", package = "vcd") for a worked example.
