dlcompare: Direct label comparison plot

In directlabels: Direct labels for multicolor plots in lattice or ggplot2

Description

Compare several plots and/or label placement methods. This creates a custom grid graphics display based on lattice and/or ggplot2 output. Plots will be on the columns and positioning methods will be on the rows.

Usage

dlcompare(plots, pos.funs, rects = TRUE, row.items = "plots", 
    debug = FALSE)

Arguments

plots	List of ggplot2 or lattice plots. List names will be used to annotate the plot.
pos.funs	List of label placement methods to apply to each plot. List names, or function names if specified as character strings, will be used to annotate the plot.
rects	Draw rectangles around each plot, creating a grid?
row.items	If "plots" then put plots on the rows and method on the columns. Otherwise, do the opposite.
debug	Show debug output?

Examples

library(lattice)
library(ggplot2)
oldopt <- lattice.options(panel.error=NULL)

## Compare two plots of the same data using lattice and ggplot2.
dts <- cbind(male=mdeaths,female=fdeaths,time=1:length(mdeaths))
require(reshape2)
ddf <- melt(as.data.frame(dts),id="time")
names(ddf) <- c("time","sex","deaths")
plots <- list(lattice=
              xyplot(deaths~time,ddf,groups=sex,type="l",xlim=c(-15,80)),
              ggplot2=
              qplot(time,deaths,data=ddf,colour=sex,geom="line")+xlim(-10,80))

if(names(dev.cur())!="postscript"){##to avoid error on pkg check Try
  ## Use some exotic labeling options with different rotation, font
  ## face, family, and alpha transparency.
  exotic <- list("last.points",
                 rot=c(0,180),
                 fontsize=c(10,20),
                 fontface=c("bold","italic"),
                 fontfamily=c("mono","serif"),
                 alpha=c(0.25,1))
  dlcompare(plots,list(exotic))
}

## Compare a legend with direct labels on the same plot.
library(nlme)
ggrat <- qplot(Time,weight,data=BodyWeight,
               colour=Rat,geom="line",facets=.~Diet)
pfuns <- list("legend","direct labels"="last.qp")
dlcompare(list(ggrat),pfuns,rects=FALSE,row.items="posfuns")

lattice.options(oldopt)
