Getting the through items from a has_many :through :uniq relationship In a nutshell, I have been using the has_many :through :uniq relationship, and I want a DRY way to list the join model objects. Currently, my objects include taxon objects, toxin objects, data_object objects, and taxon_toxin_citation objects ("citation" is another word for data_object). A taxon has many data objects, has many taxon_toxin_citations, and has many toxins through taxon_toxin_citations. As well as a taxon causing many toxins, a toxin can be caused by many taxa. And there a...

...ame) self.set_item(i,1,data.code) self.set_item(i,2,data.description) i = i + 1 end end I think it would be better to subclass Wx::ListItem and add instances of this class to the List. Something like this (not tested): class MyListItem < Wx::ListItem def initialize(data_object, *args) super(*args) # here I need to add the column data, but I don''t know how end end my_list.add_item(MyListItem.new(data_object)) But I have no idea how I can fill the columns in my ListItem-Object. Any ideas how I can do this? I think it should work with ListItem#se...

Hi list, I have problems with the as.numeric function. I have imported probabilities from external data, but they are classified as factors as str() shows. Therefore my goal is to convert the colum from factor to numeric level with keeping the decimals. I have googled the problem for a while now and kept to several advices like

I am looking for a way to save a plot (graphics contents) to a file after the plot has been calculated but before it has been rendered. More specifically, assume that I made a plot that took a very long time to produce, I would like to save this plot to a generic file that I can later, on a different machine, render to either PDF, PNG, SVG using the usual R graphics devices, without recalculating

The integration of plot methods for various outputs from rms packages is a great appreciated aspect of the rms package. I particularly like to use: plot(summary(model)) for my own purposes, but... for publication/presentation I need to modify details like variable names, or the number of signficant digits used in the figure annotations. Is there a simple way to modify the plot inputs
