Dear Whom it may concern, I need help to figure the "macro" function in R: I need to plot the different data sets by a plotxyf function, I want the title to be different for different data set. # get the data set final.xyf<- xyf(data=as.matrix(my.final), Y=classvec2classmat(final$outcome), xweight = 0.5, grid=somgrid(5, 4, "hexagonal")) #plot function plotxyf<-function (data) { plot(data, type="mapping", labels=final$target, col=final$outcome+1,, main="Supervised: Mapping plot for data") } #use the plotxyf function. plotxyf(final.xyf) But the result is not I expected, the title is "Supervised: Mapping plot for data", not "Supervised: Mapping plot for final.xyf" CAn anyone help me with this? Thanks so much! -- Sincerely, Changbin -- [[alternative HTML version deleted]]
