 ## Note
 Added support for computing moments and statistics.
 
+Changed doi format (brackets) in DESCRIPTION according to 
+comment from Uwe Ligges from 
+10.1641/0006-3568(2001)051[0341:lndats]2.0.co;2
+to
+10.1641/0006-3568(2001)051%5B0341:lndats%5D2.0.co;2

+And changed back to original doi after second comment 
+by Uwe Ligges

 ## Test environments
+with old doi
 * local R 3.4.4 on Mint17 64bit
 * Ubuntu 14.04.5 LTS (on travis-ci), 14.04
 * win-builder (devel)
 * R-Hub
