Hi! The example code from ?interp and ?akimaInterp works for me, without apparent problems. I observe that the difference between the two plots you attached appears to be that one of them is not complete. The regions that have been drawn appear identical on first glance. As you may be aware, RKWard is only a frontend to the "R" software environment. Further a lot of functionality available in R is not maintained by the R project itself, but is provided by contributed packages, in this case "akima". The issue you are experiencing is very likely not directly related to RKWard, and neither to R, but to the akima package. As one simple test, try running your code in a plain R session outside of RKWard, to test whether you observe the same symptoms, there. If, after that, you believe that the problem is really specific to RKWard, then please provide us with more specifics. Preferrably this would be an example R script which we can run to reproduce the problem. Also, please include information on the versions of R, RKWard, and akima in use (output of sessionInfo()). If you think the problem is more likely specific to the akima package, the maintainer of this package is listed as "Albrecht Gebhardt <albrecht.gebhardt at uni-klu.ac.at>" at http://cran.r-project.org/web/packages/akima/index.html . Most likely this is the person you should contact. Most likely this person will also ask you for an example R script, and the output of sessionInfo(). I hope this will help you to find a solution.
