dl.move: Manually move a direct label

In tdhock/directlabels: Direct Labels for Multicolor Plots

Description

Sometimes there is 1 label that is placed oddly by another Positioning Function. This function can be used to manually place that label in a good spot.

Usage

dl.move(group, x, y, 
    ...)

Arguments

group	Group to change.
x	Horizontal position of the new label.
y	Vertical position of the new label. If missing(y) and !missing(x) then we will calculate a new y value using linear interpolation.
...	Variables to change for the specified group

Value

A Positioning Function that moves a label into a good spot.

Examples

if(require(ggplot2)){
  library(lattice)
  scatter <- xyplot(jitter(cty)~jitter(hwy),mpg,groups=class,aspect=1)
  dlcompare(list(scatter),
            list("extreme.grid",
                 `+dl.move`=list(extreme.grid,dl.move("suv",15,15))))
  p <- qplot(log10(gamma),rate,data=svmtrain,group=data,colour=data,
             geom="line",facets=replicate~nu)
  adjust.kif <- dl.move("KIF11",-0.9,hjust=1,vjust=1)
  dlcompare(list(p+xlim(-8,7)),
            list("last.points",
                 `+dl.move`=list(last.points,adjust.kif)))
}
