similar to: NetCDF output in R

Hi, I am using the package ncdf to create netCDF files and I want to mimic the the header of an exiting netCDF file created outside of R. Below is what the existing header looks like (part of it that is different): netcdf ccd1984_05_08 { dimensions: lat = 1974 ; lon = 1894 ; time = UNLIMITED ; // (1 currently) variables: int time(time) ;

Hello, I have a problem writing a variable to an existing file. Below is a part of my script and how it fails. I can't find "create.var.ncdf" in help Thanks for any help. Mark nc <- open.ncdf(ncname, readunlim=FALSE, write=TRUE ) missing <- 1.e+30 xdim <- nc$dim[["west_east"]] ydim <- nc$dim[["south_north"]] tdim <- nc$dim[["Time"]]

I would like to open an existing netCDF file and add a variable to it. I am using the ncdf package. This test code gives the idea of what I am trying to do: library(ncdf) print('here we go') print('first, construct netCDF file') t<-dim.def.ncdf('t','',1:1,unlim=T,create_dimvar=F) print('defining first vars')

Dear All, I am a research student in environment. I have only little programming knowledge. I am currently doing the last project about rainfall impact on ground water quality in an area. It happens that I have to use R to read rainfall data (3 dimension) from ASC file (*.asc), and then write them into one NCDF file (*.nc). I have been working very hard on study R, but I

Dear List, does anybody has experience with the RNetCDF package? I manage to open a connection and copy data from a ncdf file but would need a way to automatically retrieve variable names (ideally all of them from one file) and units from the file. Any ideas? Jannis

Hello I am a new user of R . and I ve problem with R and netcdf . I succed installation , I could use all examples . But when I take my netcf it is different . I want to do statistic on this kind of file . 1) first calculate mean . my data is like that through ncdump -h test.nc netcdf test { dimensions: lat = 301 ; lon = 401 ; time = UNLIMITED ; // (80 currently)

How to programmatically (i.e., without no or minimal handcoding) copy a netCDF file? (Without calling > system("cp whatever wherever") :-) Why I ask: I need to "do surgery" on a large netCDF file (technically an I/O API file which uses netCDF). My group believes a data-assimilation error caused a data variable to be corrupted in a certain way, so I'm going to

Dear R Users, I am using R 2.14.1 on windows How to read netcdf files in R ? Which packeges do we need to install for this, and what commands are used for reading netcdf files.

Dear all I'm a newbie regarding netcdf data. Today I realized that I maybe do not understand some basics of the netcdf. I want to create a *.nc file containing three variables for Switzerland. All data outside of the country are NAs. The third variable is calculated from the first two variables. Basically there is no problem to do that. I copy the file with the data of the first variable,

Hi List, I am building a package for a client to help them create and perform analyses against netcdf files which contain 'a temporal stack' of grids. For my examples and test cases, I create an example dataset in code (as this is a lot more space efficient than providing raw data). The code creates a netcdf file in tempdir() and an object of class 'ncdf' in the global namespace.

Dear all, I am attempting to convert 10 NetCDF files into a single NetCDF file, due to the data input requirements of a model I hope to use. I am using the ncdf package, version 1.6. The data are global-scale water values, on a monthly basis for 10 years (ie. 120 months of data in total; at present the data are separated by year, with 12 months of data in each file - mrunoff_1986 through to

Hi All, i'm on a debian linux 64bit, i'm tying to install the netcdf intraface, i tried both ncdf and ncdf4 but trying to build i received the error : (i have necdf installed on my machine and it is able to fiund it .. no missed .h) epy at epinux:~$ sudo R CMD INSTALL --configure-args="-with-netcdf_incdir=/usr/include -with-netcdf_libdir=/usr/lib" ncdf4_1.8.tar.gz *

Friends, I tried to install ncdf package in ubuntu with the following command. R CMD INSTALL --configure-args="-with-netcdf_incdir=/apps/netcdf/4.0.1/gcc/include -with-netcdf_libdir=/apps/netcdf/4.0.1/gcc/lib" ncdf_1.6.tar.gz The installation was stopped throwing the following error. I tried to google it but didnt find any solution. someone kindly write me what is going wrong. **

I am trying to create a NetCDF file with bathymetry (a matrix) and then to add a grid type (an integer) as variables. This is the relevant part of the code: library(ncdf) wfile="my_file.nc" msv=-10 grdtp=2 # Dimensions d1=dim.def.ncdf("lon","degrees",as.double(lon)) d2=dim.def.ncdf("lat","degrees",as.double(lat)) # Variables

Dear R users I am attempting to add lncdf_1.6.tar.gz libraries within R, and have failed. I have R version 2.8.1, and are running on fedora 10 Kernel Linux 2.6.293.-60.fc10.x86_64.

Dear All, I recently got a 64bit machine and had netcdf-3.6.2 installed. Then I tried to install ncdf package but got the following error message when using netcdflib: gcc -std=gnu99 -I/home/ljin/share/R-2.6.1/include -I/home/ljin/share/R-2.6.1/include -I. -I/usr/local/include -fpic -g -O2 -c ncdf2.c -o ncdf2.o gcc -std=gnu99 -I/home/ljin/share/R-2.6.1/include

Hi everyone, I am a newbie in R and in this discussion list. I am trying to use R package "ncdf" to read values of temperature from a NCDF file. I did it before to another file using the function "get.var.ncdf", but now there is an error that I can not solve, and I would really appreciate if you could help me. I am using R version 2.11.1 (2010-05-31) in a machine with Linux

Hi, I'm using the "ncdf" library for creating ncdf files. But I need to create about 100 variables per file (e.g. single rivers), So I do not like to create each variable separately. Unfortunately I found no way to make this work, as I'm unable to create a correct list of class "var.ncdf". ###code piece river=list(mode='var.ncdf', length=nriv)
