[R-sig-Geo] point and click visualization of data

[van Etten, Jacob (IRRI)]

Dear Chuanwen

You could write a new function around identify() that looks for the
observation ID, looks up the corresponding picture and plots it. None of
the spatial packages will do this automagically.

Dear all,

I am not sure if this question is related to spatial analysis or not. 
I searched CRAN task View, it seems this is the only place.

The data we are working on is multivariate data, where each observation
has p features(variables). For each observation, all features are
computed/subtract from a picture, i.e., one observation correspondents
to one picture, which is then summarized by a p-dimension vector(
features). 

Now in a x-y plot of two features ( variables), we want to click or
select some observations, could it possible to bring up the
correspondent pictures of those observations ? In R, I know identify()
function. But here we want to bring up the pictures. Any package can do
this ?

Thank you very much for your time!
Chuanwen
