I run R 3.0.1 through Eclipse and have no problem. I tried to execute some of my R scripts using Rscript.exe but i get the following error:
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'H:/R/R-3.0.1/library/rJava/libs/x64/rJava.dll':
LoadLibrary failure: The specified path is invalid.
I have checked and the DLL exists in the directory.
Do you have any suggestion?
Thanks.
Regards
Solved by Adding
if (Sys.getenv("JAVA_HOME")!="")
Sys.setenv(JAVA_HOME="")

I have successfully installed all the libraries but below error is not going away
I have tried 3 JDK java-se-8u41-ri ; openjdk11 ; openjdk8 and below error keeps coming, when I open in R-Studio it works but not whe i try to make exe using electron, please advise
stderr:Error: package or namespace load failed for 'qdap':
.onLoad failed in loadNamespace() for 'rJava', details:

LoadLibrary failure: %1 is not a valid Win32 application.
I have R installed in a usb stick (since I'm using work computer and don't have Admin access to install software), and so far I've been having to resort to read.csv() since I can't use any library to read excel files.
For example, XLConnect gives the problem of :
>Error: package or namespace load failed for ‘XLConnect’:
>> .onLoad failed in loadNamespace() for 'rJava', details:<br>
>> call: inDL(x, as.logical(local), as.logical(now), ...)<br>
>> error: unable to load shared object 'D:/R/R-4.0.2/library/rJava/libs/x64/rJava.dll':<br>
> LoadLibrary failure: %1 is not a valid Win32 application.<br>
>In addition: Warning message:
>package ‘XLConnect’ was built under R version 4.0.3
It seems that these libraries (readxl, xlsx, or XLConnect) are failing because they don't know where I have Java installed. So, I also did this:
Sys.setenv(JAVA_HOME='C:\Program Files (x86)\Java\jre1.8.0_131\bin')
but, to no avail. (that advice I got it from https://www.r-statistics.com/2012/08/how-to-load-the-rjava-package-after-the-error-java_home-cannot-be-determined-from-the-registry/)
If someone knows how to read excel files using R from a memory stick - I would really appreciate if they can point north to me.
btw, this is the error when loading xlsx library:
> library(xlsx)
>Error: package or namespace load failed for ‘xlsx’:
>> .onLoad failed in loadNamespace() for 'rJava', details:<br>
>> call: inDL(x, as.logical(local), as.logical(now), ...)<br>

>> LoadLibrary failure: %1 is not a valid Win32 application.

>In addition: Warning message:<br>
>package ‘xlsx’ was built under R version 4.0.3
and this is the error when trying to read an excel file with readxl (no problem when loading):
>*Error in loadNamespace(name) : there is no package called ‘cli’*
This is it, this did it:

Thank you kind stranger.
I'm very new to R and I'm having problems right off the bat. None of the packages want to load and each time I try, the same error message is being given (see below). What am I doing wrong? Thanks in advance for any help!
library(xlsx)
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
Error: package ‘rJava’ could not be loaded
I have since added JAVA_HOME to my environmental variables but now when I attempt to load a package, a new error pops up (See Below)
library(xlsx)

I'm using x64 windows 7 and R i386 3.1.1
I installed 'tm.plugin.webmining' package. but when I load this package using
library(tm.plugin.webming)
flowing error occure:
Error : .onLoad is failed at loadNamespace() because of 'rJava':
Call: inDL(x, as.logical(local), as.logical(now), ...)
Error: Cannot load 'C:/Program Files/R/R-3.1.1/library/rJava/libs/i386/rJava.dll':
LoadLibrary failure: Cannot find the module.
I already installed latest jvm. But it doesn't work.
try setting the Java_Home path on R
Sys.setenv(JAVA_HOME="path/java/home")
ie
Sys.setenv(JAVA_HOME=C:/Program Files/Java/jdk1.8.0_05/bin")
I'm trying to set up MPI with DeinoMPI on Windows. I've installed DeinoMPI and have my cluster set up there, but when I run library(Rmpi) after starting Rgui.exe through the cluster I get the following error:
> library(Rmpi)
Error : .onLoad failed in loadNamespace() for 'Rmpi', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'D:/Programs/R-3.1.0/library/Rmpi/libs/x64/Rmpi.dll':
LoadLibrary failure: The specified module could not be found.
In addition: Warning message:
package ‘Rmpi’ was built under R version 3.1.1
Error: package or namespace load failed for ‘Rmpi’
Looking at that directory, Rmpi.dll is present in the directory and has read/write access. Anyone have any ideas why it says 'the specified module could not be found'? Or is there some additional config necessary perhaps?
Additionally, if I run Rgui.exe outside of the DeinoMPI cluster and run library(Rmpi), I receive the following pop-up:
