Dear all, I noticed that a data.frame has four attributes: - names - row.names - class - variable.labels While one can use the first three (i.e. names(foo) or class(foo)), the fourth one can only be used via: attributes(foo)$variable.labels (which is kind of a tedious thing to type) Is it or would be possible to simply use: variable.labels(foo) like the first three attributes? I tried: varlab

Dear all, In order to ease the transition from SPSS to R for some of my colleagues, I am trying to create a function which would show the variables and their labels (if those exist), using function "label" in package Hmisc. A toy example would be this: my.data <- data.frame(age=c(24,35,28), gender=c("Male", "Female", "Male")) require(Hmisc)

...except get the correct label. How do I get access to the factor level being plotted in each panel within my custom axis function? It may be easier to illustrate than explain, so here is a dummy example, including a version of my custom axis function. require(lattice) ## custom axis function axis.VarLabs <- function(side, ...) { if(isTRUE(all.equal(side, "top"))) { M <- function(lims) min(lims) + (diff(lims) / 2) xlim <- current.panel.limits()$xlim panel.axis(side = side, outside = TRUE, at = M(xlim), tck = 1, line.col = "black&...

...bal variables for data sets in a package". I went to look at the Check results for one of my packages (analogue) on CRAN: http://cran.r-project.org/web/checks/check_results_analogue.html Under the r-devel build machines I'm seeing a lot of things like this: Stratiplot.default : axis.VarLabs: no visible global function definition for ?current.panel.limits? Stratiplot.default : axis.VarLabs: no visible global function definition for ?panel.axis? Stratiplot.default : axis.VarLabs: no visible global function definition for ?which.packet?
