+Description: Provides a powerful framework for evolutionary
     computing in R. The user can easily construct powerful evolutionary algorithms
     for tackling both single- and multi-objective problems by plugging in different
     predefined evolutionary building blocks, e. g., operators for mutation,
     recombination and selection with just a few lines of code. Your problem
     cannot be easily solved with a standard EA which works on real-valued vectors,
-    permutations or binary strings? No problem, ecr has been developed with that in
+    permutations or binary strings? No problem, 'ecr' has been developed with that in
     mind. Extending the framework with own operators is also possible. Additionally
     there are various comfort functions, like monitoring, logging and more.
