Hi,

For me, three solutions :
 - You can find existing packages which will install your library 
(https://testtoolshed.g2.bx.psu.edu/view/jeltje/package_dnacopy_1_40_0/118417199f06
 
<https://testtoolshed.g2.bx.psu.edu/view/jeltje/package_dnacopy_1_40_0/118417199f06>).
 So you will just need to link a requirement 
(https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax#A.3Crequirements.3E_tag_set
 
<https://wiki.galaxyproject.org/Admin/Tools/ToolConfigSyntax#A.3Crequirements.3E_tag_set>)
 and a tool_dependencies.xml file
 - If not, you can write your own package. But thanks to Ross Lazarus, to deal 
with dependencies of dependencies of dependencies, there is a tool for that 
https://testtoolshed.g2.bx.psu.edu/view/fubar/biocdepgen_r_3_1_2/faafc60f3d6a 
<https://testtoolshed.g2.bx.psu.edu/view/fubar/biocdepgen_r_3_1_2/faafc60f3d6a>
 - If you lack of time, you install R and needed libraries on your serveur.

Unfortunately, I can’t explain you why you couldn’t install your library 
through your script because R use to allow installing in the user home.
