Redesign of the RPACT websites

Wed Nov 10

The relaunch of the RPACT websites has been completed. This is new:

• The information on the adaptive clinical trial design with R as well as on our services and products is now available in a much clearer and more appealing way
• The collection of currently 25 practical clinical trial design examples and use-cases, the so-called rpact vignettes, now can be filtered and are searchable
• The customer-exclusive content is now bundled on a clearly structured page to be found under "My Account" in the main menu of www.rpact.com
• The rpact package website www.rpact.org has a vignette-typical clean and simple design and only contains information about the R package rpact
