Dear Jian,
I would like help you but I need that you explain a little bit about what you
really want.
Sorry ask you again, but may be I don´t understood because my difficulties on
english.
Anyway, try this:
require(akima)
x=runif(100,0,100)
y=runif(100,0,100)
dbh=runif(100,1,100)
rdata=data.frame(x,y,dbh)
rdata.interp<-interp(rdata$x, rdata$y, rdata$dbh)
image(rdata.interp)
Of course you can output to ASCGRID using adehabitat package
Kind regards,
miltinho
Brazil

Assunto: [R] How to plot the grid figure using R?
Now I have the forest plot data with x, y locations, and I measured the DBH for
every indivicuals.
The data looks like that:
x=runif(100,0,100)
y=runif(100,0,100)
dbh=runif(100,1,100)
rdata=data.frame(x,y,dbh)
> rdata[1:5,]
x y dbh
1 99.5354145 1.412844 34.10112
2 0.8259361 87.737036 39.12914
3 6.5678613 65.699032 22.55990
4 67.2987881 72.053877 45.83978
5 2.2491372 23.622898 68.77065
My question is: How can I plot the grid (25ï½25,5ï½5,...) figure by DBH?
Can you introduce a simply method to do it by R language? I know that it can be
done very easy by the software ArcGis.
