I am trying to invoke an in house developed java program from R and am running into some confusing issues. I've written this function: DoNormalSkew <- function() { .jaddClassPath("U:/development/software/untilities/ELVeSkew/dist/ELVeSkew.jar") .jpackage("U:/development/software/utilities/ELVeS/dist/ELVeSkew.jar") .jcall("java/lang/System", "V", method=Main.main(), "U:/development/software/utilities/ELVeSkew/test/csv",...

I haven't had time to try using R for over a year, but have a colleage who wants to. We work with time series and our current version of our calendar-time subroutines in java converts both directions between linear time and calendar. We have used calendar time since year 1965 starting out then with Fortran. Calendar time can be CnYrMoDa | CnYrMoDaHr | CnYrMoDaHrMn | CnYrMoDaHrMnSc |

Hi everyone, I want to call a Java application from R and have encountered some problems with the way rJava deals with the system class loader. To run my application, I use the following R script: > library(rJava) > .jinit() > .jaddClassPath("myApp.jar") > rWrapper <- .jnew("org/test/RWrapper") > .jcall(rWrapper,"V","start") My Java application has a plugins loading mechanism that uses a specific PluginClassLoader to load plugins stored in additional JAR files (e.g. plugin.jar). This Pl...
