Hi,
I'm using the densCols function for a scatterplot and cannot figure out 1) how
to extract the computed densities, and 2) how to create a legend based that
represents the upper and lower ranges of the densities.
For example:
movers.den <- densCols(move$x, move$y)
table(movers.den)
#08306B #083775 #083B7C #083D7E #3989C1 #3F8FC4
28 22 101 25 4 5
#4392C6 #65AAD3 #69ACD5 #6CAED6 #77B4D8 #98C6DF
14 6 8 4 3
9
plot(move, col=movers.den, pch=20,ylab="y coordinate movement (meters)",xlab="x
coordinate movement (meters)")
abline(h=0, v=0, col = "grey", lty=2)
#legend??
Any help would be appreciated!
Kate
