Dear R Users,
I am trying to plot a matrix (a Digital Elevation Model) using wireframe
[lattice] and color that matrix based on a separate/independent matrix of
the same resolution (both have the same number of rows and columns) as the
DEM. More specifically I would like to plot a DEM using wireframe and
color each cell/tile based on interpolated surface temperature
measurements. Within the wireframe function, the arguments
"color.regions", "drape" and "at" seemed most important to accomplish
this. However, I have not been successful. Below is another explanation
with some example data.
###
#say we have a matrix
DEM=matrix(1:100, ncol=10)
#we also have a matrix of interpolated temperatures measurements (or any
other kind of data with the same resolution as the DEM)
interpTEMP = matrix(floor(runif(100, 1,10)),ncol=10)
#I would normally go through and apply a function to use html color codes
to coincide with interpTEMP but these values will prove my dilemma.
#now I would like to plot my DEM and color each cell based on the
"matching" cell of interpTEMP
#N.B. that this obviously isn't the correct way of doing things as it
doesn't work!
wireframe(x=DEM, drape=TRUE, col.regions=as.vector(interpTEMP))
###
any ideas on how to combat this problem? Please let me know if I need to
be more clear or provide additional information. Many blessings for your
help!
