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

Dear all

[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
