               alpha, cex, srt = 0, lineheight, font,
               fontfamily, fontface, adj = c(0.5, 0.5),
               pos = NULL, offset = 0.5, ...)

panel.brushpoints(x, y = NULL, col, pch, alpha,
                  fill, cex, ...)

panel.brushlines(x, y = NULL, type, col, alpha,
                 lty, lwd, ...)

Details

The settings for panel.usertext are taken from trellis.par.get("user.text"), but default to trellis.par.get("add.text") if undefined. "user.text" is preferred to "add.text" for annotations because the latter also applies to strip text and key text. The settings for panel.brushpoints are taken from trellis.par.get("brush.symbol"), but default to hard-coded settings if undefined. The settings for panel.brushlines are taken from trellis.par.get("brush.line"), but default to hard-coded settings if undefined. These functions are used in playwith.
