Thanks, Liviu In a first look it seems OK. Two questions: 1. Playwith accept directly the plots created by the ca package, but it seems unable to identify the point labels For example: data(smoke) smoke ca(smoke) plot(ca(smoke)) playwith(plot(ca(smoke))) Then, if I try to identify a label playwith gives the message "Sorry, can not guess the data point coordinates. Please contact the maintainer with suggestions". If I ask to select the label from a table playwith sends the following message to RGui: "Error in data.frame(..., check.names = FALSE) : arguments imply differing number of rows: 2, 0" 2. Can playwith draw ellipses or any other figure around selected points?
(For the first question it seems my fault, but I don't know how to fix it) Hug --- On Wed, 2/3/10, Liviu Andronic <landronim...@gmail.com> wrote: > From: Liviu Andronic <landronim...@gmail.com> > Subject: Re: [R] Interactively editing point labels in a graph > To: "trece por ciento" <el13porcie...@yahoo.com> > Cc: r-help@r-project.org > Date: Wednesday, February 3, 2010, 3:49 AM > Hello > > On 2/3/10, trece por ciento <el13porcie...@yahoo.com> > wrote: > > Dear experts, > > I would like to be able to interactively (if > possible, with mouse and clik) edit point labels in graphs, > > > Try playwith. > Liviu > > > particularly in multivariate graphs, such as the > biplots you get after a correspondence analysis (with, for > example, package ca), where labels tend to overlap.
