I'm trying to run parallel computing. Hence I install package Rmpi.
install.packages("Rmpi")
require("Rmpi")
Could you please elaborate why there is such error message while I've just installed the package?

Hi so I'm having trouble with R studios on my desktop where it won't let me open any packages.
When I attempt to install a package with install.packages() like Tidyverse I get this error.
Error in library("tidyverse") : there is no package called ‘tidyverse’
Show in New Window Error in install.Rtools() : could not find function

Then when I try to load the package into my library with library("tidyverse") I receive this error
Error: package or namespace load failed for ‘tidyverse’ in inDL(x, as.logical(local), as.logical(now), ...):
unable to load shared object 'C:/Program Files/R/R-4.1.2/library/stats/libs/x64/stats.dll':
LoadLibrary failure: The specified module could not be found.
This error isn't just for tidyverse but all packages I try to run. I have uninstalled R and RStudios multiple times, but the error doesn't go away. I have been to IT at my university and they were completely baffled. Please help if you can, I really need R to work for both my job and classes.
i dont know why i have this error.
since i had aleardy set all of the environment variable, rtools, r, rstudio and home path to D:\DANNY HUANG\Documents correctly
p.s. i set the installation program's path to D disk since i don't have enough space in OS disk,

I added the following and then rJava loaded without error.
Sys.setenv(JAVA_HOME='C:\\Program Files\\Java\\jre1.8.0_221')
I have successfully installed the RJDBC in RStudio.

I manually checked the file path and ROracle.dll is there.
EDIT:
I have RODBC and RJDBC working. I just don't understand why ROracle won't install:

I'm guessing there are Oracle files that need installing, but none of the documentation is very clear.
In order for ROracle to install and load properly, you should have Oracle Client 64-bit and Windows 64-bit. Once I installed 64-bit Oracle Client on my machine, this error went away.
