我希望在R x64 3.1.2中加载rJava.OS- Windows 8.1 64位
虽然安装似乎工作正常:
> install.packages("rJava")
Installing package into ‘C:/Users/sony/Documents/R/win-library/3.1’
(as ‘lib’ is unspecified)

加载包时出错:
library(rJava)
Error in get(Info[i, 1], envir = env) :

In addition: Warning message:
In …我已经安装了最新版本的R(2.15.2)和Java(7.11),并通过RStudio(0.97.310)我试图加载rJava包.它似乎正确安装,但当我打电话时,library(rJava)我收到以下错误:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: stop("No CurrentVersion entry in '", key, "'!
Try re-installing Java and make sure R and Java have matching architectures.")
error: object 'key' not found
Error: package/namespace load failed for ‘rJava’
rJava的文档引用了Java 1.5+,所以我想知道是否需要安装古老版本的Java来解决这个问题.任何帮助将非常感激!
