Hi All, and Heberto,
Did you ever resolve your installation problem with rJava?
I have a new windows 7 machine and can't seem to get it installed correctly.
I do have Java installed. I download rJava without proble, then:
As you didn't follow the posting guide, we don't know if this is 32-
or 64-bit R on 32- or 64-bit Windows.
If you are running 64-bit R you need 64-bit Java, and similarly for
32-bit. The message you show indicates that you do not have the
appropriate Java installed.
As I have pointed out already this week, rJava has its own mailing
list, so please follow up there.
install.packages("rJava")
Installing package(s) into ‘C:\Users\Patrick\Documents/R/win-library/2.12’
(as ‘lib’ is unspecified)
trying URL

The downloaded packages are in
C:\Users\Patrick\AppData\Local\Temp\Rtmp9zcM7g\downloaded_packages
Looks like it downloaded fine to my eyes. But in the next step I get an
error:
library(rJava)
Error in utils::readRegistry(key, "HLM", 2) :
Registry key 'Software\JavaSoft\Java Runtime Environment' not found
Error in utils::readRegistry(key, "HLM", 2) :
Registry key 'Software\JavaSoft\Java Development Kit' not found
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: fun(...)
error: JAVA_HOME cannot be found from the Registry
Error: package/namespace load failed for 'rJava'
I'm not sure how to check where R is looking for rJava vs where it lives,
this seems to be an issue in other posts, although they have different
errors.
I'm a novice still at R. I see a lot of posts on this topic, but few are
recent. Help would be much appreciated.
Thanks!
