installation issues with units

[dmcglinn]

I would like to check out the package but I'm having trouble installing the dependency units. I've posted the error below. If you can offer a suggestion I would greatly appreciate it. I am on ubuntu and I do have udunits installed and working from the terminal:

  libudunits2.so not found!

  If the udunits2 library is installed in a non-standard location, use:

    --configure-args='--with-udunits2-lib=/usr/local/lib'

  for example, if the library was not found, and/or

    --configure-args='--with-udunits2-include=/usr/include/udunits2'

  if the header was not found, replacing paths with appropriate values for your
  installation. You can alternatively use the UDUNITS2_INCLUDE and UDUNITS2_LIBS
  environment variables.

  If udunits2 is not installed, please install it.
  It is required for this package.

Also it may be worth noting that on my Windows machine I have no trouble installing the dev version of the package. I did not try the CRAN version.

Hi,

this rather seems to be an issue with the specific installation of a units dependency, so I am not sure I can really help here. If udunits2 is installed, try to provide the location using --configure-args as suggested in the error message. I'll close the issue for now.

Thanks for the message @azizka! Is "units" performing a really important task in the package? If this dependency can be easily dropped then I would encourage you to consider it to reduce install barriers. Thanks!
