+## Resubmission
+This is a resubmission. In this version I have:
+
+* Removed all linebreaks in the Authors-section and removed unnecessary spaces in the Description-section in the DESCRIPTION-file.
+* Removed one reference to a web-address in the documentation select_features.
+* Removed all \dontrun{} statements. Added an inst/extdata folder containing data which is used in the examples via system.file().
+* Removed a default path of the function write_csv.
+* In the tests and the examples to write_csv, all files are written into a temporary directory and are removed afterwards.
+
