[R] Multiple Graphs with heatmap

2007-08-06 Thread Joseph Retzer
I'd like to plot a heatmap along with a silhouette plot and clusterView plot in the same graphic window however both heatmap and heatmap.2 create a new window and will not appear with other graphs when using the par(mfrow= ) option. Does anyone have an alternative which would put these plots

I'm building a RF 50 trees at a time due to memory limitations (I have roughly .5 million observations and around 20 variables). I thought I could combine some or all of my forests later and look at global importance. If I have say 2 forests : tree1 and tree2, they have similar Gini and Raw

[R] cex in xlab, ylab and zlab of persp

2007-03-15 Thread Joseph Retzer
I've had no success using what I think is the correct code to change the default size of the x, y and z labels in a persp graph (i.e. cex.lab). Is there a particular specification to accomplish this? Many thanks, Joe Retzer [[alternative HTML version deleted]]

[R] plot.randomForest default mtry values

2007-03-15 Thread Joseph Retzer
When using the plot.randomForest method, 3 error series (by number of trees) are plotted. I suspect they are associated with the 3 default values of mtry that are used, for example, in the tuneRF method but I'm not sure. Could someone confirm? Also, is it possible to force different values of

I don't seem to be able to label the x, y or z axis when creating a 3d chart using rgl.surface. I'd like to have them parallel to the axis line and move with the graph when rotated. Can this be done? Many thanks, J. Retzer [[alternative HTML version deleted]]
