## Draw Individual Picture Paths

### Description

This function individually draws each path from a `"Picture"` object.

### Usage

    picturePaths(picture, nr, nc,
                 col = "black",
                 fill = "light grey",
                 freeScales = FALSE,
                 xscale = NULL, yscale = NULL,
                 label = function(n) {
                   tg <- textGrob(n, x = 0, y = 0,
                                  just = c("left", "bottom"),
                                  gp = gpar(fontsize = 6))
                   grid.rect(x = 0, y = 0,
                             height = unit(6, "points"),
                             width = grobWidth(tg),
                             just = c("left", "bottom"),
                             gp = gpar(fill = "white"))
                   grid.draw(tg)
                 }, use.gc = TRUE)

### Arguments

`picture` | A `"Picture"` object.
`nr` | Number of rows of paths to draw.
`nc` | Number of columns of paths to draw.
`col` | Colour of border drawn around each path.
`fill` | Background colour drawn behind each path.
`freeScales` | A boolean indicating whether each path should be drawn on its own scale. If `FALSE`, all paths are drawn on a common scale. If `TRUE`, `xscale` and `yscale` are ignored.
`xscale` | A numeric vector of length two indicating the minimum and maximum on the x-scale.
`yscale` | A numeric vector of length two indicating the minimum and maximum on the y-scale.
`label` | Function to draw a label on each path. If any value other than a function is specified, no labels are drawn.
`use.gc` | A boolean indicating whether to use the graphical parameter information in the path.
