Install rJava in R - rjava

I have R and Java installed on C:\Program Files. I am receiving this message when i try to load the rJava library. I have successfully installed the rJava package. thanks.
library(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.
Error: package or namespace load failed for ‘rJava’

Is your Java_HOME path variable the same for both installations.
Try echo $JAVA_HOME and see what happens?
Also the installation suggests that you need to install the JDK not just the java library.
Here is a link the most recent JDK:

Issue installing Tax4Fun

I'm trying to install the package "Tax4Fun" but keep failing.
I've tried 2 different ways:
install.packages("devtools")
devtools::install_url("http://tax4fun.gobics.de/Tax4Fun/Tax4Fun_0.3.1.tar.gz")
library(Tax4Fun)
The error that I get is:
ERROR: dependency 'biom' is not available for package 'Tax4Fun'
I've also tried installing biom directly
BiocManager::install("biom")
which does not work either
Bioconductor version 3.10 (BiocManager 1.30.10), R 3.6.1 (2019-07-05)
Installing package(s) 'biom'
Installation path not writeable, unable to update packages: boot, foreign, KernSmooth,
mgcv, nlme, survival
Warning message:
package ‘biom’ is not available (for R version 3.6.1)
The other way I've tried to install Tax4Fun directly is
BiocManager::install("Tax4Fun")
I get the following error code:
Bioconductor version 3.10 (BiocManager 1.30.10), R 3.6.1 (2019-07-05)
Installing package(s) 'Tax4Fun'
Installation path not writeable, unable to update packages: boot, foreign, KernSmooth,

Warning message:

Please help :)
You need to install it by downloading the packages from source (http://tax4fun.gobics.de). Then it depends whether you are running on Linux/Mac or Windows.
From the command line, you navigate to the folder containing the .tar.gz downloaded package. Then you should install it using:
R CMD INSTALL Tax4Fun_0.3.1.tar.gz
But dependancies are not installed by default. So you need to install dependancies manually, Qiimer and Biom, which are both deprecated on Cran. You install them using the same command, after you have downloaded the packages from the Cran archives.
Before that, you need to also install their dependancies in R:
install.packages("pheatmap")
install.packages("RJSONIO")
Then you should be able to proceed as mentioned above: install Qiimer and Biom from the command line first. Then Tax4Fun from the command line too.
If you are running on Windows you should have quite the same issues, but the installation of the different packages and dependancies is different. You can have a look at the readme at http://tax4fun.gobics.de

tidyverse package will not load

I am running the latest version of Rstudio (1.1.453) on Mac. Since installing the latest version of R-Studio, I can no longer get tidyverse package to load. Any suggestions on how I can fix this?
I get the following error message.
> library("tidyverse", lib.loc="/Library/Frameworks/R.framework/Versions/3.5/Resources/library")
Error: package or namespace load failed for ‘tidyverse’ in loadNamespace(i, c(lib.loc, .libPaths()), versionCheck = vI[[i]]):
there is no package called ‘dplyr’
Have you tried installing it with dependencies:install.packages("tidyverse", dependencies = TRUE)
I had a similar issue and if this doesn't fix it, try to install dplyr manually: install.packages("dplyr")

Installing and loading "rJava"

I am encountering problems loading the "Deducer" package due a loading problem with "rJava". The installation of "rJava" seems to be done correctly, yet it fails when calling it to load.
Please, can anyone shed some light of wisdom? :)
Error : .onLoad failed in loadNamespace() for 'rJava', details:
call: stop("No CurrentVersion entry in '", key, "'! Try re-installing Java and make sure R and Java have matching architectures.")
error: object 'key' not found
Error: package/namespace load failed for ‘rJava’
On xubuntu 12.04 with javac 1.7.0_21 set as default via:
$ sudo update-alternatives
then
$ sudo R CMD javareconf
$ sudo R
> update.packages()

Agave dependency error

I am trying to install Agave under Fedora, but I got this error:
configure: error: gnome-doc-utils >= 0.3.2 not found
I tried to compile and install the gnome-doc-utils from this page, but i still got this error,and when i try the
yum list installed gnome-doc-utils*
command, I can't find the package. Do I have to register the package after installing? I don't think I have a error for the make install, because I don't see any the text error in the process, or I could be wrong.
In general, package managers (tools like yum) don't know that something has been installed on your machine unless it was installed as a package. If an agave package for Fedora exists, I would suggest using that instead of compiling from source.

Error building openssl-sys crate on Windows

I am trying to compile a Rust program on Windows, but I get this error message:
Compiling openssl-sys v0.6.4
failed to run custom build command for `openssl-sys v0.6.4`
[...]
failed to execute command: The system couldn't find the specified file. (os error 2)
Is `gcc` not installed? (see https://github.com/alexcrichton/gcc-rs#windows-notes for help)
--- stderr
thread '<main>' panicked at 'explicit panic', C:\Users\User\.cargo\registry\src\github.com-0a35038f75765ae4\gcc-0.3.12\src\lib.rs:510
Cargo compiled every other package without problem, but it can't compile the openssl package.
I searched for help with this specific error and found a github issue for hyperium. The first answer references the openssl building guide for Windows.
I don't understand exactly how I have to build openssl in Windows. I installed MinGW and added the bin path to the global PATH variable, so gcc is reachable, but this did not solve the error.
I use Rust 1.2 and Cargo 0.4.0. My project is an example for a Telegram API wrapper.
1) Download ssl
Installs Win32 OpenSSL v1.0.2d
Install it here: C:\OpenSSL-Win32,C:\OpenSSL-Win32\include,C:\OpenSSL-Win32\lib
2) Install MinGW,and add system env path ,,C:\MinGW\bin,important,MinGW's installed path contain char 'MinGW '
3) cmd run env OPENSSLLIBDIR=C:/OpenSSL-Win32/lib OPENSSLINCLUDEDIR=C:/OpenSSL-Win32/include cargo build
