### ** Examples

# Examples use swirl dataset, for description type ? swirl
data(swirl)

# Microarray color palettes
Gcol <- maPalette(low = "white", high = "green", k = 50)
Rcol <- maPalette(low = "white", high = "red", k = 50)
BYcol <- maPalette(low = "blue", mid="gray", high = "yellow", k = 50)

# Color images of green and red background and foreground intensities
##image(swirl[, 2], xvar ="maGb")
##image(swirl[, 2], xvar ="maGf", subset = TRUE, col = Gcol, contours = FALSE, bar = TRUE, main="Swirl array 93")
##image(swirl[, 1], xvar ="maRb", contour=TRUE)
##image(swirl[, 4], xvar ="maRf", bar=FALSE)

# Color images of pre-normalization intensity log-ratios
##image(swirl[, 1])

# Color images with overlay spots
##image(swirl[, 3], xvar = "maA", overlay = maTop(maA(swirl[, 3]), h = 0.1, l = 0.1), bar = TRUE, main = "Image of A values with % 10 tails highlighted") 

# Color image of print-tip-group
##image(swirl[, 1],xvar = "maPrintTip")
