udunits2 R install: udunits2.h not found

Question

I'm trying to install udunits2 in R in order to satisfy the dependency for the ggforce package. However, the installer keeps failing on the check for udunits2. I have tried the instructions in this (udunits 2 devel is installed as shown here.) and this thread, which produces the same result as trying to install.packages('udunits2').

I was able to get it working on my Mint machine by just installing udunits2-dev, however I'm quite new to Fedora, and am not sure what is causing this.

System info:

Fedora 28, R-3.4.4

EDIT

Error output when trying to install using install.packages("udunits2", configure.args = "--with-udunits2-lib=/usr/bin/udunits2"):

-----Error: udunits2.h not found-----
     If the udunits2 library is installed in a non-standard location,
     use --configure-args='--with-udunits2-lib=/usr/local/lib' for example,
     or --configure-args='--with-udunits2-include=/usr/include/udunits2'
     replacing paths with appropriate values for your installation.
     You can alternatively use the UDUNITS2_INCLUDE and UDUNITS2_LIB
     environment variables.
     If udunits2 is not installed, please install it.
     It is required for this package.

Answer 1

On Fedora the header file is installed in /usr/include/udunits2, c.f. this Github issue. Solution provided there:

sudo yum install udunits2-devel

Followed by:

install.packages("udunits2",configure.args='--with-udunits2-include=/usr/include/udunits2/')
