Question on netcdf4 required by vat

[hmorzaria]

Christopher:

Hi, I've tried to install vat but run into an error with dependency on netcdf4. I wanted to see if you had any suggestions. If I am running R in a 64-bit Windows 7 system. If I run 32-bit R,install netcdf4 for 32bit and try to install vat I get an error that netcdf is not installed on arch x64. Conversely if I run 64-bit R,install netcdf4 for 64bit and try to install vat I get an error that netcdf is not installed on arch xi386.

Thanks!

Have you installed ncdf4 prior to loading the package? On Windows, it looks like you don't have a binary available. Can you try, launching R in 64 bit, and

install.packages("ncdf4", type = "source')

If so, try

library("ncdf4")

Does that load OK? If so, then run

devtools::install_github(repo = "cddesja/vat")

I haven't tested vat on a Windows machine, so I'd be happy to hear about any success/failure you might encounter. Also, it might depend on where exactly R is installed. I can get access to a Windows machine, however, if this bug persists.

I just installed a Windows virtual machine and was unable to replicate your issue. However, I did a few things that might be different from what you've done.

1) I installed R-64 only to C:/ 2) I installed http://www.unidata.ucar.edu/downloads/netcdf/ftp/netCDF4.3.3.1-NC4-64.exe to C:/ 3) I installed the binary of the ncdf4 package from here: http://cirrus.ucsd.edu/~pierce/ncdf/ 4) I then ran install.packages("ncd4f_1.12.zip", repo = NULL, type = "source") 5) Then I install vat follow the instructions on the GitHub site.

See if that makes a difference.

Hi, I am closing this issue because I haven't heard back for you and because this isn't an issue with the vat package but instead with the ncdf4 package on Windows..
