I've been playing around with qdataFrameModel and have the following comments:<br><br>* NA for integer values prints a crazy string "-21474...". For numeric it prints "inf".<br>* factors print out as their integer representation<br>
<br>For this, and other reasons, it might be nice to be able to set the display role (rather than it be the default) via .name.display<br><br></blockquote><div><br>The display can be fixed up. I've recently done that for RGtkDataFrame.<br>

Only other option really is '_'. Could take a completely different approach of specifying role - column mappings as extra parameters to the function. I was not a big fan of that, because it is not as self-contained.<br>

<br></blockquote><div><br>Perhaps it would have been a better idea to implement this in R. As it stands, there's no interface for subclassing it. <br> </div><blockquote class="gmail_quote" style="margin: 0pt 0pt 0pt 0.8ex; border-left: 1px solid rgb(204, 204, 204); padding-left: 1ex;">
