...no encuentro la forma de reproducir el gráfico de las puntuaciones factoriales . Usando gvisScatterChart puedo dibujar los puntos pero no sé cómo poner un color para cada especie. Lo que he hecho es library(googleVis) data(iris) mod <- prcomp(iris[, 1:4]) scores <- as.data.frame(mod$x) chart2<- gvisScatterChart(scores) plot(chart2) Pero no sé como hacer para que tome un color distinto según la Especia. Podrían unir ggplot2 y googlevis ;) Saludos
