Dear all, Considering this simple example of hexbinplot: mixdata <- data.frame(x = c(rnorm(5000), rnorm(5000,4,1.5)), y = c(rnorm(5000), rnorm(5000,2,3)), a = gl(2, 5000)) fig <- hexbinplot(y ~ x | a, mixdata) print(fig) update(fig, colramp = BTC) produces a bad (non-updated) legend. Compare it with: hexbinplot(y ~ x...

Hello, I would like some help to plot a vertical line on a scatterplot build with hexbin package. I just need to plot a vertical line on the graph to mark a threshold value on x axis. It would be better if the parameter of the plot line function respect the x axis scale. Thanks, Rodrigo [[alternative HTML version deleted]]

Hello, I'm using the R package called mvpart, which is about the multivariate regression trees. The function I wrote is: mrt1<- mvpart(coefmat~sChip+sScreen+sMem,data=mixdata, xv="pick", plot.add=TRUE,uniform=TRUE,which=4,all=TRUE,xadj=2,yadj=2,rsq=TRUE,big.pts=TRUE,wgt.ave.pca=TRUE,legend=TRUE,bars=F, pca=TRUE) where "coefmat" is a matrix(of dimension N*K) to store the coefficients of my functional data object; and the predictors in the formula are...
