character. dimension reduction name
- dim1_to_use
numeric. dimension to use on x-axis
- dim2_to_use

- show_plot
logical. show plot
- return_plot
logical. return ggplot object
- save_plot
logical. save the plot
- save_param
list of saving parameters, see
showSaveParameters
- default_save_name
default save name for saving, don't change, change save_name in save_param
