Hi,
I am rather new to the Renku platform, and I am having trouble using the R package “sf”, which I need to plot some maps.
I created my project using the R template, and I am using the RStudio environment. Installing the package with
```auto
install.packages('sf')
```
works fine, but when I load the package I get the following error:
```auto
Error: package or namespace load failed for ‘sf’ in dyn.load(file, DLLpath = DLLpath, ...):
unable to load shared object '/usr/local/lib/R/site-library/units/libs/units.so':
libudunits2.so.0: cannot open shared object file: No such file or directory
```
What should I do to fix this? Thanks in advance.

Found out how to solve the problem: install the required dependencies, as described in [https://github.com/r-spatial/sf](https://github.com/r-spatial/sf). I added
```auto
apt-get install -y libudunits2-dev libgdal-dev libgeos-dev libproj-dev
```
at the appropriate location in the Dockerfile.
