Dear CSAG R users,
I will be glad if someone can point out what I am doing wrong or not doing at
all in this.
I am trying to write out netcdf file in R. I have 26 time step but only the
first time step is written.
For example:
>library(ncdf)
>path <- '/home/work/'
>forecast <- open.ncdf(paste(path,'cam.1980.2005.nc',sep=""))
> fore <- get.var.ncdf(forecast,'ppt')
> lon <- get.var.ncdf(forecast,'lon')
> lat <- get.var.ncdf(forecast,'lat')
>dim(fore)[3]
>26
> times <- 1:dim(fore)[3]
> write.netcdf.time(paste(path,'cam_fore.nc',sep=""), fore,lon,lat,times)
[1] "put.var.ncdf: warning: you asked to write 1440 values, but the passed data
array has 37440 entries!"
[[1]]
[1] 6
Warning message:
In 1:nt : numerical expression has 26 elements: only the first used
################# function for writing out the netcdf file #############
write.netcdf.time <- function(filename='outputfile.nc',data,lons,lats,nt){
lon <- dim.def.ncdf('lon','degrees_east',lons)
lat <- dim.def.ncdf('lat','degrees_north',lats)
times <- 1:nt
tdim <- dim.def.ncdf('time','days since 1980-01-01', times, unlim=TRUE)
# levs <- dim.def.ncdf('lev','pressure',levs)
var <- var.def.ncdf('data','unitless',list(lon,lat,tdim),-999.9)
ncid <- create.ncdf(filename,list(var))
put.var.ncdf(ncid, var, data)
close.ncdf(ncid)
}

Thank you.
