After updating to the latest version of Rstudio (R version 3.4.1 (2017-06-30) -- "Single Candle") I cannot seem to get the XLConnect Package to load. This is the error message I get:
> library('XLConnect')
Loading required package: XLConnectJars
Error: package or namespace load failed for ‘XLConnectJars’:.onLoad failed in loadNamespace() for 'rJava', details:
call: dyn.load(file, DLLpath = DLLpath, ...)

Reason: image not found
Error: package ‘XLConnectJars’ could not be loaded
R also throws a similar error message when I try to load the rJava package as well. I have tried uninstalling both Java and R and have scoured SO for answers, but nothing seems to work.
I am running macOS Sierra (10.12.6)
Would anyone be willing to offer any help?
The error suggests that there is an issue loading rJava. Try updating the Java configuration variables via R CMD javareconf or sudo R CMD javareconf.

I'm trying to install the Homals package - library(homals), but keep getting this error message:

I have a couple of my colleagues to run the same code, the same thing happens. I have re-install R studio to the newest version.
install.packages("rgl")
install.packages("homals")
library(homals)
Any solutions for this? thank you.
I was able to successfully install on both Windows and Mac. I believe the root cause here is that you have R version 3.3 installed when you require at least v3.5.3 as per below:
library(homals)
Warning message:
package ‘homals’ was built under R version 3.5.3
I tried to find solutions from previous posts, but they do not solve my problem.
I am using macOS High Sierra and have Java installed. Below is the error reported by Rstudio. Also, rJava, Mac, and R are really messy with each other. I found this post but still does not work.

I met the same question and I found this is helpful.
Cannot load R xlsx package on Mac OS 10.11
1.In terminal enter the following to relink Java correctly:
sudo R CMD javareconf
2.Back in R (or RStudio) install the rJava package from source:
install.packages("rJava",type='source')
Then
library(rJava)
and
library(RWeka)
should work.
I'm trying to load the RSiena package into R, but keep getting this error message:
Error: package or namespace load failed for ‘RSiena’:
.onLoad failed in loadNamespace() for 'tcltk', details:
call: dyn.load(file, DLLpath = DLLpath, ...)
error: unable to load shared object '/Library/Frameworks/R.framework/Versions/3.4/Resources/library/tcltk/libs/tcltk.so':

Reason: Incompatible library version: libtk8.6.dylib requires version 11.0.0 or later, but libfontconfig.1.dylib provides version 10.0.0
I tried installing three ways:
install.packages("RSiena") , install.packages("RSiena", repos="http://R-Forge.R-project.org") , and installing straight from tgz file (from https://cran.r-project.org/web/packages/RSiena/index.html).
The first two installation methods do not give any error and say The downloaded binary packages are in /var/folders/mk/__r_sbzn5mx88x04mrlycsg00000gq/T//RtmpbxlMY8/downloaded_packages.The third option gives this message Error in install.packages : type == "both" cannot be used with 'repos = NULL'
None allow me to load the package. I'm working with R version 3.4.3 (2017-11-30) in RStudio Version 1.1.423 on Mac OS X El Capitan (version 10.11.6).
I've tried uninstalling and reinstalling. I'm not sure how else to troubleshoot this issue.
The most recent version (RSiena v.1.2.26) of rsiena addresses tcltk issues, and is now available on Github here: https://github.com/snlab-nl/rsiena.
SOLUTION. I installed XQuartz from xquartz.macosforge.org and now the package loads successfully.
I am running MacOS 10.13 (High Sierra) and recently updated to R version 3.4.3 and R studio version 1.1.419. For some reason the rJava package is not working...tried several fixes from here on stackoverflow and nothing works. Also, the digest package will not load so I can no longer use ggplot2. Any suggestions?

New Mac OSX releases have a documented problem of messing up the Java path in R/RStudio (see here). It looks as though that this is what you're encountering here.
If you check out the question I've linked above, hopefully you can find a solution that works to reset your path; both of the commands below worked for me.
dyn.load('/Library/Java/JavaVirtualMachines/jdk1.8.0_66.jdk/Contents/Home/jre/lib/server/libjvm.dylib')
or
sudo ln -s $(/usr/libexec/java_home)/jre/lib/server/libjvm.dylib /usr/local/lib
I don't know about the problem with rJava, but digest was just updated so if you try to install the binary it may not compiled and built yet. If that ever happens (it's somewhat of a race condition/lag), you can try to reinstall form source:
install.packages("digest", type = "source")
Bear in mind that I am computer illiterate and new to R. I have installed the rJava package in R studio version 1.0.143 and installed Java 8 (using MacOS Sierra). When I try to load the rJava package:
library(rJava)
I get the following error
Unable to find any JVMs matching version "(null)".
No Java runtime present, try --request to install.

Could somebody help me to interpret this error message? There is probably a very simple solution, but I am completely lost. Thank you!!
As noted in Unable to load rJava in RStudio, there is a very specific sequence of steps that must be taken to get rJava to work on a Macbook, as documented in rJava Issues #86.
Download and install Java from Oracle
Uninstall any previously installed version of rJava
Add JAVA_HOME to your .bashrc
Close & restart terminal, R and RStudio sessions so they pick up the updated JAVA_HOME
Use install.packages() to install rJava
See the URL link above for additional details on each step.
