gradient: gradient

In jedgroev/makekml: kml including heading

Description

Generates a kml including the heading

Usage

gradient(x, y, colors, len = c(0.1, 0.2), pos = NULL, dist = c(0.1,
  0.1), place = "upperright", bars = 5, tdist = 0.04, labels = c(0,
  1), title = NULL, tdisttitle = 0.04, font = 1, tcol = "white")

Arguments

x	= x axis values
y	= y axis values
colors	= vector of colors
len	= width of the bar given as a proportion of x and y axis
pos	= maximum x and y coordinate
dist	= the distance from the border
place	= placement of the bar in the plot window (upperright, lowerleft, upperleft, lowerright)
bars	= number of bars to distinguish in the gradient
tdist	= distance of text from gradient bar
labels	= vector with min and max value
tcol	text color of labels and title
if	pos is null dist and place can be used to set the position of the
If	pos is null than dist (distance from border) and place (upperright, lowerleft, upperleft, lowerright) is used to determine the position

Examples

EXAMPLE 1 
x <- 1:100
y <- (1:100)/5
colors <- colorRampPalette(c('grey90','grey20'))(100)
plot(x,y, col=colors)
gradient(x,y, col=colors)
EXAMPLE 2 
If there are less than 20 colors no bars are plotted 
colors <- colorRampPalette(c('grey90','grey20'))(10)
plot(x,y, col=colors)
gradient(x,y, col=colors)
EXAMPLE 3  
x <- 1:100
y <- (1:100)/5
colors <- colorRampPalette(c('grey90','grey20'))(100)
plot(x,y, col=colors)
Add gradient using pos (values of x and y axis) or using dist (distance from border) and place (upperright, upperleft,...)
gradient(x,y, col=colors, pos=c(21,18)) # using pos 
gradient(x,y, col=colors, dist=c(0.1,0.1), place = 'upperleft') # using dist and place
