“unable to load shared object” when loading the rJava library
I apologize in advance for my bad english, i hope that someone can help me.
I have to load an Excel file .xlsx on R, but:
library(xlsx)
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/danil/Documents/R/win-library/3.4/rJava/libs/x64/rJava.dll':
LoadLibrary failure: Impossibile trovare il modulo specificato.
Error: package ‘rJava’ could not be loaded
So, i tried to install Java, Java SE-Development Kit 10 and Java Runtime Environment 10, 64 bit for both. But, also in this case:
library(rJava)
Error: package or namespace load failed for ‘rJava’:
.onLoad failed in loadNamespace() for 'rJava', details:
call: inDL(x, as.logical(local), as.logical(now), ...)
error: unable to load shared object 'C:/Users/danil/Documents/R/win-library/3.4/rJava/libs/x64/rJava.dll':
LoadLibrary failure: Impossibile trovare il modulo specificato.
What can i do?

This was happening to me as well (also Windows 10), and the problem with mine was that the environment variable was not set properly. In my case, I had to do
Sys.setenv('JAVA_HOME' = 'C:/Program Files (x86)/Java/jre1.8.0_161/')
Just change the folder name to where Java lives in your computer, and let me know if this doesn't work out.

Do you happen to know why do we need to setenv() for JAVA_HOME in R, when I had already set JAVA_HOME in system variables? Using Windows 10
