Bar plot of a RasterLayer
Create a barplot of the values of a RasterLayer. For large datasets a regular sample with a size of approximately maxpixels is used.
## S4 method for signature 'RasterLayer' barplot(height, maxpixels=1000000, digits=0, breaks=NULL, col=rainbow, ...)

A numeric vector (or matrix, when beside = TRUE) of the coordinates of the bar midpoints, useful for adding to the graph. See barplot
f <- system.file("external/test.grd", package="raster")
r <- raster(f)
barplot(r, digits=-2, las=2, ylab='Frequency')
op <- par(no.readonly = TRUE)
par(mai = c(1, 2, .5, .5))
barplot(r, breaks=10, col=c('red', 'blue'), horiz=TRUE, digits=NULL, las=1)
par(op)Please choose more modern alternatives, such as Google Chrome or Mozilla Firefox.
