R help - Apr 2011 - Problem Installing rJava on MS Win 7 Platform

I''m a new R user and, frankly, this problem has got me stumped.

 

I''m using the 64 bit version of RGui and followed the installation
instructions on http://www.rforge.net/rJava/

 

Here is the result:

 

package ''rJava'' successfully unpacked and MD5 sums checked
> 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 don''t Have the faintest idea as t what I''ve done, or failed
to do.

 

Assistance will be greatly appreciated.

 

Thanks in advance.

You failed to install an appropriate Java version.
