gganatogram and gganimate

Today I wanted to see if I could create a slideshow of pictures from the gganatogram package. I wanted to combine them with the gganimate package, but I have not figured out how to get that to work. (In particular, the gganatogram() function seems to return a different list layout than ggplot objects.) library(gganatogram) ## Loading required package: ggpolypath ## Loading required package: ggplot2 library(gganimate) library(profvis) N <- 25 # number of cell samples num_cell_parts <- nrow(cell_key$cell) # randomly select a random number of cell parts part_picker <- sample(1:num_cell_parts, sample(1:num_cell_parts, 1)) cell_num <- rep(1, length(part_picker)) this_cell <- cell_key[['cell']][part_picker, ] cell_samples <- cbind(this_cell, cell_num) for(j in 2:N){ part_picker <- sample(1:num_cell_parts, sample(1:num_cell_parts, 1)) cell_num <- rep(j, length(part_picker)) this_cell <- cbind( cell_key[['cell']][part_picker, ], cell_num) cell_samples <- rbind(cell_samples, this_cell) # figure_list[j] <- gganatogram(data = this_cell, # outline = FALSE, fillOutline='steelblue', organism="cell", fill="colour") + # theme_void() + # coord_fixed() png(filename = paste0(j, ".
