In addScales: Adds Labeled Center Line and Scale Lines/Regions to Trellis Plots

Description

S3 generic and scaledTrellis method to remove all scaling information from a scaledTrellis object, returning the prior unscaled trellis object.

Usage

revert(obj,...)
## S3 method for class 'scaledTrellis'
revert(obj, ...)

Arguments

obj	An object inheriting from class scaledTrellis.
...	Currently ignored

Details

Returns the last version of the trellis object with all addScales scales and legends removed. Note that this is not the original trellis object if that was subsequently modified by update calls. See the examples.

Examples

## Using simple artificial data
set.seed (2233)
x <- rep(1:10,4)
y <- rnorm(40, mean = rep(seq(10, 25, by = 5), each = 10),
           sd = rep(1:4, each = 10))
f <- rep(c("AA","BB","CC","DD"), each = 10)
##
## trellis plot the data with "free" y axis sxaling
orig <- xyplot(y ~ x|f, type = c("l","p"), col.line = "black",
       scales = list(alternating =1,
                     y = list(relation = "free")),
       as.table = TRUE,
       layout = c(2,2),
       main = "revert() Example"
)
## Plot it
orig

## Remove the y axis scales and add horizontal scalelines
orig <- update(orig, scales = list(alternating =1,
            y = list(relation = "free", draw = FALSE)))
upd1 <- addScales(orig)
## Plot it
upd1
class(upd1)

## revert
upd2 <- revert(upd1)
## Plot it
upd2
class(upd2)

## clean up
rm(x, y, f, orig, upd1, upd2)
