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') a<-var.def.ncdf('a',...

Friends, I tried to install ncdf package in ubuntu with the following command.

I tried to google it but didnt find...

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 mrunoff_1995). For each month there are 720 longitude x 360 latitu...

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] &...

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 pie...

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 2....

...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 still can not fix the problem. Could someone please as kind as point out that what the problems are in my R script? Firstly, this is an example of data in asc file: NCOLS 241...

...mpiled to have position independent code. I.e., the -fpic or -fPIC flag was not supplied when compiling. Your build log showed that -fpic was used when compiling your code, but the 3rd party library, libnetcdf.a may not have been compiled this way. The command eu-findtextrel /usr/lib/R/library/ncdf/libs/ncdf.so will tell you which parts of ncdf.so were not compiled with -fpic. If you cannot recompile libnetcdf.a then you may have to turn off some the security enhancements.
