Examples using apply over arrays in an RGList
# Maximums apply(RG$R, 2, max, na.rm=TRUE) apply(RG$Rb, 2, max, na.rm=TRUE) apply(RG$G, 2, max, na.rm=TRUE) apply(RG$Gb, 2, max, na.rm=TRUE) # Examining backgrounds that are higher than foreground apply(RG$R < RG$Rb, 2, sum, na.rm=TRUE) apply(RG$G < RG$Gb, 2, sum, na.rm=TRUE)
