OS X Yosemite
R 3.1.3
Colleagues
I have used the package xlsx successfully in the past. Today, I attempted to
use that package, the first time since I upgraded to Yosemite. R responded to:
library(“xlsx”)
with
No Java runtime present, requesting install.
A popup then said “you need to install the legacy Java SE 6 runtime”
I updated all my packages, then I tried:
library(“rJava”)
The outcome is the same.
I installed Java (Java 8 Update 40), then tried again. Same problem. I can
confirm that Java is installed:
> PET633> java -version
> java version "1.8.0_40"
> Java(TM) SE Runtime Environment (build 1.8.0_40-b27)
> Java HotSpot(TM) 64-Bit Server VM (build 25.40-b25, mixed mode)
It appears that the rJava wants an old version of java — however, I can’t find
that version at the Oracle website. For curiosity, I tried to install Java SE
7 — the installer would not allow this once it found the newer version (8).
This suggests that installing version 6 will also not be permitted.
Any thoughts?
