set_vsearch_executable specifies the valid command to
invoke VSEARCH.
Value
Nothing is returned, but the option Rsearch.vsearch_executable
is updated. The string is also saved to a file for later R sessions, i.e. you
only need to update this once (or if you change how you run/install VSEARCH).
Details
Use this function to change the command used to invoke the external
software VSEARCH on this computer. When the Rsearch package is
installed this command is by default just "vsearch".
If you have a windows computer and have copied the binary vsearch.exe
to the folder C:/Documents/ on your computer, you update R with this
information by set_vsearch_executable("C:/Documents/vsearch").
You may use the function vsearch to test if the command is
valid.
