R help - Nov 2009 - How to plot an image in R

Dear all
Im new in R
I have a necdf data set that I want to plot :
this is my data set


[1] "file Tmax.DJF.daily.1981_1999.echama2.nc has 4 dimensions:"
[1] "longitude   Size: 127"
[1] "latitude   Size: 110"
[1] "ht   Size: 1"
[1] "t   Size: 1680"
[1] "------------------------"
[1] "file Tmax.DJF.daily.1981_1999.echama2.nc has 1 variables:"
[1] "float temp[longitude,latitude,ht,t]  Longname:TEMPERATURE AT 1.5M
Missval:2.00000004008175e+20"

I have done this but I dont know how to plot the graph.
data<-open.ncdf("Tmax.DJF.daily.1981_1999.echama2.nc")
lon<-get.var.ncdf(data,"longitude")
lat<-get.var.ncdf(data,"latitude")
temp<-get.var.ncdf(data,"temp")
time<-get.var.ncdf(data,"t")



Thanks in advance

You are going to have to subset the necdf dataset by dates or some other
logical aggregation scheme, and then plot.

Since the data is spatial, I would think that plotting could be achieved
with the image( ) function.


Good Luck
