Install udunits2 package for R3.3

I just wasted the whole day trying to figure out how to install the udunits2 package to be able to install the units package to be able to install the ggforce and ggraph packages.

I'm trying to install it on Ubuntu 16.04, and R >= 3.3 since ggforce was built under R 3.3.

I followed these instructions here: https://github.com/edzer/units/issues/1

Although I have libudunits-2.0 and udunits installed on my machine (as sudo apt-get install udunits2 doesn't find a udunits2 package), and the PATH to the libudunits-2 and udunits locations on my $PATH, in R when I try installing udunits2, units or ggforce I'm getting an error that says,

-----Error: libudunits2.a 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.

So, umm, it's looking for the udunits2.h and libudunits2.a files.... So, I downloaded udunits2 from CRAN, unpacked it and put it in my R library. Then, if I put library(udunits2, lib.loc = "my library dir") I get an error saying it's not installed. So, when I install.package('udunits2', repo = NULL, libconfig.args = '--with-udunits2-lib=/home/fjay/R/x86_64-pc-linux-gnu-library/3.3') or install.packages('units',....) or install.packages('ggforce',...) it is still looking for these files...and, after inspection of the udunits2 package these files are not in any of the udunits2 folders.

If anyone knows how to install this udunits2 packages please help me!

I had the same problem. Following the first answer from here you have to install -dev version of udunits:

sudo apt-get install libudunits2-dev

Then the installation of udunits2 and ggforce goes without any error.

EDIT:

Following the comments below, for CentOS7 it should be:

sudo yum install udunits2-devel

And for MacOS:

brew install udunits

I have installed the udunits2 package in R on the Linux platform (redhat) without Internet connnection.

I also had this problem.

Firstly, I installed the udunits2 (not the R package udunits2)in the Linux example at (/usr/include/udunits2).

Secondly, running this command worked: install.packages("udunits2_0.13.tar.gz",configure.args='--with-udunits2-include=/usr/include/udunits2')

I hope this experience could help you.

This won't be any help to the chap that asked the question, but I was just having the same issue on a computing cluster without root access and the following worked:

homedir <- Sys.getenv("HOME")
udunits_dir <- file.path(Sys.getenv("HOME"), "udunits")
system(paste0("mkdir ", udunits_dir))
system(paste0("wget --directory-prefix=", udunits_dir, " ftp://ftp.unidata.ucar.edu/pub/udunits/udunits-2.2.25.tar.gz"))
owd <- getwd()
setwd(udunits_dir)
system("tar xzvf udunits-2.2.25.tar.gz")
setwd(file.path(udunits_dir, "udunits-2.2.25"))
system(paste0("./configure --prefix=", udunits_dir, "/local"))
system("make")
system("make install")
setwd(owd)
Sys.setenv(LD_LIBRARY_PATH=paste0(Sys.getenv("LD_LIBRARY_PATH"), ":", udunits_dir, "/local/lib"))
install.packages("udunits2", 
                 type = "source",
                 configure.args = c(paste0("--with-udunits2-include=", udunits_dir, "/local/include"), 
                                    paste0("--with-udunits2-lib=", udunits_dir, "/local/lib")),
                 repos = "http://cran.rstudio.com")
dyn.load(paste0(udunits_dir, "/local/lib/libudunits2.so.0"))
install.packages("units", repos = "http://cran.rstudio.com",
             configure.args = c(paste0("--with-udunits2-include=", udunits_dir, "/local/include"), 
                                paste0("--with-udunits2-lib=", udunits_dir, "/local/lib")))
