Hi I am having a problem with plot () and ggplot (). When I call one of
these functions, the plotting area starts to look as though it is working,
but nothijg ever is visible. Unless it was a dendrogram. Woth the bar
chart, the plotting area just had an x and y axis and nothing else. I tried
a bar chart with ggplot and i tried to plot a tree result from rpart (). I
couldnt see anything plotted. Is there some way I should be
troubleshooting this? Im thinking its an R config I did or didnt do. I
really have no idea though.
