Dear list: I would like to override the default way R formats plot axes with a custom method(s). Obviously I would prefer to define it as general as possible avoiding writing a custom method for each individual class where possible.
The plot.default method (and I assume other methods as well) calls Axis(...) to produce the axis layout depending on data. In this sense it seems reasonable to (re)define Axis methods rather than change plot methods (which are impossible to control as there can be too many custom ones). Now my question is how can I redefine Axis that it is automatically called by plot.default and other plot methods? Or which Axis-method signatures are already defined that I should redefine? What I have succeeded so far was defining Axis.numeric and Axis.myClass, which are called by default if I supply data of class numeric or myClass. For example, a simple code like Axis.numeric = AxisFUN = function(x=NULL, at=NULL, ..., side, labels=TRUE) { if (is.null(at)) at = pretty(x) axis(at=at, ..., side=side, labels=labels, col="red", lwd=5) } run with plot(1:5,1:5) will format both axes red. However, if I execute it with plot(1:5) only x axis plotting is intercepted leaving y at default formatting although it is also numeric. Why and what should I define to intercept for plotting the y axis or for plotting axes in boxplot etc. Simply importing and overriding Axis as function does not bring anything, it wouldn't get called. Also I was not able to use S4 methods to redefine Axis. Overriding it with the code from above using any of the following signatures also didn't work for me - they are simply ignored: setGeneric("Axis") setMethod("Axis", signature(x="missing",at="numeric"), AxisFUN) setMethod("Axis", signature(x="numeric",at="missing"), AxisFUN) setMethod("Axis", signature(x="missing",at="ANY"), AxisFUN) setMethod("Axis", signature(x="ANY",at="missing"), AxisFUN) setMethod("Axis", signature(x="ANY",at="ANY"), AxisFUN) Any ideas?
