The tkBrush function in the TeachingDemos package may help. If you just want to see where a selected point apears in each of the pairwise plots based on selecting it in 1 plot then this function will do that for you (note it depends on having installed the tcltk package as well).
If you need the index of a selected point then you can do something like: out1 <- tkBrush(mydata) # now select the point of interest, click to make the change persistent. which(out1$col != 'black') # this gives the observation (row) number Hope this helps, -- Gregory (Greg) L.

In high-dimension case , if I use pairs() + identify() in hope to observe all the components of the data point I selected, I get error message. Is there anyway to get around this ? Plus, I also need it to actually compare all the components of the picked data point with "mydataset" to choose the closest one. Thanks million in advance. best tong ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html ______________________________________________ [email protected] mailing list https://stat.ethz.ch/mailman/listinfo/r-help PLEASE do read the posting guide! http://www.R-project.org/posting-guide.html
