Hi, im trying to install the package RCall but I’m running in some problem.

for context:

> \>R RHOME  
> /usr/local/lib/R

> \>R --version  
> R version 3.6.3 (2020-02-29) – “Holding the Windsock”

OS: Linux Mint 19

Now, when I do

> Pkg.add(“RCall”)

Have no problem, but when I call it with

> using RCall

I get the next error

> [Info: Precompiling RCall [6f49c342-dc21-5d91-9882-a32aef131414]  
> ERROR: LoadError: RCall not properly installed. Please run Pkg.build(“RCall”)

and when I run

> Pkg.build(“RCall”)

I get the next error

I try to set the R\_HOME variable to be the same as \>R RHOME with

> ENV[“R\_HOME”] = “/usr/local/lib/R/”

But that give me same error when running Pkg.built(“RCall”).

Thanks for any help!

hmm, i wonder if setting R\_HOME via bash export would work like

```bash
export R_HOME= "/usr/local/lib/R/"

```

and then start Julia again and run
