In traudem: Use TauDEM

Finalize your installation

Once you are done, you need to register TauDEM in R and check your installation.

Register TauDEM in R

Add TauDEM to the PATH

The Windows installer might have done this automatically.
For other operating systems (macOS, Linux) use your usual method to add a directory to the PATH.

OR add an environmental variable

Add an R environmental variable called TAUDEM_PATH that points to the location where the TauDEM executables can be found (on Windows it might be C:\Program Files\TauDEM, on Ubuntu /usr/local/taudem).

For instance on Ubuntu it could be adding this line in .Renviron (see usethis::edit_r_environ()) and then re-starting R:

TAUDEM_PATH='/usr/local/taudem'

or, for just the session, running this line of R code:

Sys.setenv(TAUDEM_PATH = "/usr/local/taudem")

Check your installation

Run traudem::taudem_sitrep() and read its output carefully. Pay attention to any error that might indicate part of the installation was not successful.

If all is well (no error, only normal output from TauDEM), congratulations! Your system is ready to apply TauDEM to your own data.
