[R] rJava (installation?) problem: unable to find the basic String class
Hello, I have experienced the following problem after installing rJava (it being a prerequisite for another package in which I am relly interested). Any helpful thoughts would be appreciated: OS: Windows XP Professional 2002 SP3, have Java 6 Update 20 from Sun, also installed the JDK from http://java.sun.com/javase/downloads/index.jsp (or at least I suspect I installed it as it asked to re-boot the machine - how would I actually check?) After installing package rJava, in R:> sessionInfo()R version 2.11.0 (2010-04-22) i386-pc-mingw32 locale: [1] LC_COLLATE=English_United States.1252 [2] LC_CTYPE=English_United States.1252 [3] LC_MONETARY=English_United States.1252 [4] LC_NUMERIC=C [5] LC_TIME=English_United States.1252 attached base packages: [1] stats???? graphics? grDevices utils???? datasets? methods?? base other attached packages: [1] rJava_0.8-3 loaded via a namespace (and not attached): [1] tools_2.11.0> require(rJava)Loading required package: rJava> .jinit()Error in .jinit() : unable to find the basic String class>Any thoughts would be appreciated.
