hi; i just started using R and need to do the following. i want to plot weather data (which is in a .netCDF file). i was trying to plot some climate data for westbengal region and then i tried to interpolate the data for kolkata (which will be a subset of the oroginal data for westbengal).
i tried the following commands graphics.off() library(ncdf) library(akima) ncdata<-open.ncdf("A2.TREFHT-gis.westbengal.nc") lon<-get.var.ncdf(ncdata,"lon") lat<-get.var.ncdf(ncdata,"lat") time<-get.var.ncdf(ncdata,"time") dat <- get.var.ncdf(ncdata,"TREFHT") Kolkata <- array(dim=length(time)) vx<-as.vector(matrix(lon,nrow=length(lon),ncol=length(lat))) vy<-as.vector(matrix(lat,nrow=length(lon),ncol=length(lat),byrow=TRUE)) vz<-as.vector(dat[,,i]) ox<-as.vector(88) oy<-as.vector(22) oz<-interpp(vx,vy,vz,ox,oy,linear=TRUE) Kolkata[i]<-oz$z Kolkata<-Kolkata-273 plot(Kolkata,type="l") now the command are working fine but producing the plot for a single day only. whereas i want to plot the data for the entire time period and want a line diagram. so my question is how can i do that? please help.
