Hello,
I am working on a project where we are accessing large data files via opendap.
Myself and two of the higher-ups on the project are working on Windows
machines, and we have been unable to access remote files using the ncdf4
package. We have followed the package author's notes for installation on a
Windows machine, and we have successfully installed the netcdf-4 libraries and
the ncdf4 R package. However, the program still works only on local files. It
is not an issue with connectivity of my machine since I am able to remotely
access these same data files using Matlab.
I then attempted to follow the package author's notes on cross-compiling in a
Linux environment, I was using a Ubuntu Virtual Box. These notes are available
here: http://cirrus.ucsd.edu/~pierce/ncdf/how_to_build_on_windows.html
However, I do not really know what I'm doing and I was unable to successfully
cross-compile the dependencies. Has anyone dealt with this on a Windows
machine? Is there a different way to access remote files through R? \We have
considered writing a Python script that can be run from within an R program, so
that users that are only familiar with R can still access remote files without
downloading a lot of large files.
Any advice is appreciated.
