I have a spring boot application which is calling Rscript using Rcode and while running it on a Windows machine it is working properly, I'm trying to dockerize it.
In my docker container, I'm getting the below error.
java.util.concurrent.ExecutionException: com.github.rcaller.exception.ExecutionException: R command failed with error. Reason: Error: package or namespace load failed for ‘data.table’:
object 'as.xts' not found whilst loading namespace 'data.table'
In addition: Warning message:
package ‘data.table’ was built under R version 3.6.3
Execution halted
Tried multiple options like setting environmental variables, checking R compatibility issue.
I'm new to R, how to make sure all the required R packages are properly installed?
Not finding any workaround.
Your suggestions will be very much appreciated.

I am trying to code using the rSymPy package. When I type in library(rSymPy) I get the following warnings:
> library(rSymPy)
Loading required package: rJython
Loading required package: rJava
Loading required package: rjson
Warning messages:
1: package ‘rJava’ was built under R version 3.4.4
2: package ‘rjson’ was built under R version 3.4.4
This is fine because in theory my code should still work. However, when I try running my function which uses the sympy() command I get the following error:
> moment_generating_function(12)

Error in .jcheck() : No running JVM detected. Maybe .jinit() would help.
I then run .jinit() which produces no output. Running my code again, I now get the following error
Error in .jcall("RJavaTools", "Z", "hasField", .jcast(x, "java/lang/Object"), :
java.lang.NullPointerException
I have tried reinstalling my JDK and tried running "r cmd javareconf;" in my terminal multiple times. I would just code this directly in Python but unfortunately my assignment requires I use the rSymPy package in R. I would greatly appreciate any help with this.
So I am trying to run the
library(ggplot2)
library(qdap)
but this error keeps coming up:

I am using R in Rstudio on a mac, and I've trawled through quite a few similar questions but none seem to work. I am quite new to using R and any help would be great thanks.
I tried using
install.packages("openNLPdata")
and this showed up which I think is a good thing
trying URL 'https://cran.rstudio.com/bin/macosx/el-capitan/contrib/3.4/openNLPdata_1.5.3-4.tgz'
Content type 'application/x-gzip' length 7323402 bytes (7.0 MB)
==================================================
downloaded 7.0 MB
The downloaded binary packages are in
/var/folders/h5/_5bjqp9j0g5gqr1794sw1xwh0000gn/T//RtmpaknsV6/downloaded_packages
But the error still occurs.
Thanks in advance
It seems like that package might need rJava to run, which may not be loaded in your environment. Try:
install.packages('rJava')
library('rJava')
When trying to install package xlxs in R I get the following error.
error: No CurrentVersion entry in Software/JavaSoft registry! Try re-installing Java and make sure R and Java have matching architectures.
Not sure what to do. I have tried reinstalling Java and still get the same error.
I have R 3.12 on a windows 10 computer.
Any advice is welcome,
Thanks
Error: package or namespace load failed for ‘xlsx’:

Try re-installing Java and make sure R and Java have matching
architectures.
The error normally occurs when the architectures(32/64 bit) of java and r does not match.
In order to check the version of java, type java -version in cmd.
You can follow below given steps:
Rstudio > tools > global options > general settings > R-version > change (to the architecture same as that of java) > apply
And you're good to go.
I took over an old project from an other person. Currently I'm trying to get this project to work.
Already in the beginning I get an Exception in:
R.parseAndEval(".jengine()");
It throws a REngineEvalExcpetion: error during evaluation.
If I use R in the R-Console, I needed to add a parameter .jengine(start=TRUE) to get the command .jengine() working. So I changed this line in Java accordingly, but I still get the same Exception.
I did a tutorial with R without calling .jengine() and using Rengine instead of REngine and at least somehow it worked and I could call R commands within Java.
I'm currently using R 3.3.3 and Java 1.8. I also don't know which versions have been used previously.
"error during evaluation" just means that the R thread that is running the R script failed to run that command. But everything in the Java application is working properly. Is R that is failing.
R has to have the rJava library in order to run .jengine:
library(rJava)
.jinit(".")
.jengine(TRUE)
I am trying to run biodiversity r in r studio with the biodiversity rgui which links up to the rcmdr. I have tried every help forum to find an answer but come up with nothing. I reinstalled R, R studio, updated all packages, installed rjava and javagd and still it refuses to work. I am at wits end!!! I cannot find anything about 'hasjava' and I have updated and installed java already.
Below is copy pasted from the console.
Restarting R session...

error: could not find function "hasJava"
Error: package or namespace load failed for 'Rcmdr'
This problem has nothing directly to do with Windows or with Java.
The Rcmdr package no longer uses Java, and the function hasJava(), which was defined in and exported by the Rcmdr, no longer exists. Apparently BioDiversityR uses this function and needs to be updated appropriately.
You might report your problem directly to the maintainer of BioDiversityR.
I hope this help,
John
