Re: [R] export R-data to VisIt
Thanks Katharine, for the moment I'm not on a PC on which VisIt is installed, but it should do the trick. By the way: to use 2 variables when creating the cdf file: ncnew - create.ncdf(filename=file.cdf, vars = list(x1,x2)) That was one of the things that was working within the 2 hours ;-).
