Buenas. Esta mañana estoy trasteando un poco con googlevis, sobre todo para ver si introducimos algunos gráficos chulos en la página web de la empresa ( hacemos estudios sociológicos). Y estaba viendo esta página http://neurochem.sisbio.recerca.upc.edu/?p=276 y no encuentro la forma de reproducir el gráfico de las puntuaciones factoriales . Usando gvisScatterChart puedo dibujar los puntos

...f na.action is na.exclude. - `ncomp' is now reduced when it is too large for the requested cross-validation. - Line plot parameter arguments have been added to predplotXy(), so one can control the properties of the target line in predplot(). - MSEP(), RMSEP(), loadings(), loadingplot() and scoreplot() are now generic. See the file CHANGES in the sources for all changes. -- Ron Wehrens and Bj??rn-Helge Mevik _______________________________________________ R-packages mailing list R-packages at stat.math.ethz.ch https://stat.ethz.ch/mailman/listinfo/r-packages

Dear R-users, I would like to process some spectroscopic data with R, and I was hoping some people might have some example code on how to do this. I would like to be able to do the following things: * Detect outlier-spectra -> This can be done by using scoreplot from the pls package * Determine the range of the spectrum to be used -> For this, I should be able to calculate the regression coefficients * Determine the optimal number of elements in a model * Anything else that you guys think could be useful :-) Any help is greatly appreciated Dirk --...
