I have an xyf object from the kohonen package, and wish to plot a
lattice or grid or multiplot of a set of attributes of this object.
I've included the structure of the object below for reference, and
here is the set of plots I wish to produce, given in long-hand. I
don't know enough R to generalise this set of commands, can you help?
I am looking for a single command if possible.
op <- par(mfrow=c(2, 3)) # 6 plots in this case
plot(somdata.xyf,
type="property",
property=somdata.xyf$codes$X[, 1],
main=colnames(somdata.xyf$codes$X)[1])
plot(somdata.xyf,
type="property",
property=somdata.xyf$codes$X[, 2],
main=colnames(somdata.xyf$codes$X)[2])
... etc...
plot(somdata.xyf,
type="property",
property=somdata.xyf$codes$X[, 6],
main=colnames(somdata.xyf$codes$X)[6])
par(op)
The "codes" list of the somdata.xyf object contains a further list "X"
containing the items I wish to plot. So the properties are
somdata.xyf$codes$X[, 1:6].
Here are some of the details (snipped for clarity):
