I have a controller method as such: def delete @category = Category.find_by_name(params[:name]) @element_id = @category.name Category.delete_all(["name = ?", @category.name]) end (For the purpose of this exercise, category names are unique) I have the corresponding delete.rjs file: if @element_id page.remove :id => @element_id page.visual_effect :highlight,

Dear R users, A co-worker and I are writing a function to facilitate graph plotting in R. The function makes use of a lot of lists in its defaults. However, we discovered that R does not necessarily preserve the defaults if we were to input them in the form of list() when initializing the function.
