I had a similar issue. It is caused due the dependent package 'rJava'. This problem can be overcome by re-directing the R to use a different <code>JAVA_HOME</code>.

<pre><code>if(Sys.getenv("JAVA_HOME")!=""){
 Sys.setenv(JAVA_HOME="")
}
library(rJava)
</code></pre>

This worked for me.

Its because either one of the Java versions(32 bit/64 bit) is missing from your computer. Try installing both the Jdks and run the code. 
After installing the Jdks open R and type the code 

<pre><code>system("java -version")
</code></pre>

This will give you the version of Jdk installed. Then try loading the rJava package. This worked for me.

Answer in <a href="https://stackoverflow.com/a/7604469/3014062">link</a> resolved my issue.

Before resolution, I tried by adding JAVA_HOME to windows environments. It resolved this error but created another issue. The solution in above link resolves this issue without creating additional issues.

blocks|key|71598|text|我有一个类似的问题，对我有效的是设置JAVA_HOME。我首先在R中累了它：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|71599|Sys.setenv(JAVA_HOME+=+"C:/Program+Files/Java/jdk1.8.0_101/")|code-block|syntax|javascript|71600|当它真正起作用的时候，我把它放在|71601|系统属性->高级->环境变量|71602|通过添加新的系统变量。然后我重新启动了R/RStudio，一切都正常了。|71603|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|6|7|R|8|@]|9|@]|A|$]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

I had a similar problem what worked for me was to set JAVA_HOME. I tired it first in R:
<pre><code>Sys.setenv(JAVA_HOME = &quot;C:/Program Files/Java/jdk1.8.0_101/&quot;)
</code></pre>
And when it actually worked I set it in
System Properties -&gt; Advanced -&gt; Environment Variables
by adding a new System variable. I then restarted R/RStudio and everything worked.

blocks|key|71649|text|如果在RStudio中出现此错误，请使用Lauren's+environmental+code+above，然后在工具>全局选项中将R版本更改为32位版本。如果你有一个较新的版本，应该有32位和64位R选项。这将需要重新启动R，并限制您的内存选项。不过，不需要安装64位版本的jre。|type|unstyled|depth|inlineStyleRanges|entityRanges|offset|length|data|71650|entityMap|0|LINK|mutability|MUTABLE|url|https://stackoverflow.com/a/39985724/6461462^0|K|X|0|0^^$0|@$1|2|3|4|5|6|7|L|8|@]|9|@$A|M|B|N|1|O]]|C|$]]|$1|D|3|-4|5|6|7|P|8|@]|9|@]|C|$]]]|E|$F|$5|G|H|I|C|$J|K]]]]

If you have this error in RStudio, use <a href="https://stackoverflow.com/a/39985724/6461462">Lauren's environmental code above</a> and change your R version to the 32 bit version in Tools, Global Options. There should be both 32bit and 64bit R options if you have a newer version. This will require a restart of R, and limit your memory options. Installing the 64 bit version of the jre won't be required though.

If you have this issue with macOS, there is no easy way here: ( Especially, when you want to use R3.4. I have been there already.

For R3.3 it's a little bit easier (R3.3 was compiled using different compiler).

When I type <code>require(xlsx)</code> in order to load the package <code>xlsx</code> in R, the following messages is shown:

<pre><code>&gt; require(xlsx)
Loading required package: xlsx
Loading required package: xlsxjars
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
 call: fun(libname, pkgname)
 error: JAVA_HOME cannot be determined from the Registry
Failed with error: ‘package ‘rJava’ could not be loaded’
</code></pre>

I've also tried to load the <code>rJava</code> package manually but got this error message:

<pre><code>require(rJava)
Loading required package: rJava
Error : .onLoad failed in loadNamespace() for 'rJava', details:
 call: fun(libname, pkgname)
 error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.

Do you have any suggestion on how to solve the problem?
