Re: [R] Pruning a dendrogram based on frequencies

Hi Franklin, plot.dendrite was not designed to be pruned. I have had a look at the problem, and I may be able to suggest a way to drop values in the "dendrite" object that is the input to plot.dendrite. I'll let you know. Jim On Tue, May 8, 2018 at 11:46 PM, Franklin Mairura via R-help wrote: >

Hi Greg, This is because both plots have equally spaced x values. To see the difference, try this: plot (x_mmdd, y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480), xlab="", ylab="", col="blue") axis(1) plot (y_duration, type="l", xaxt="n", yaxt="n", ylim=range(240,480),
