SourceUrl

This is a Renjin package to make it possible to source an url, including https and allowing self-signed certificates.

You add it to you pom file as follows:

<dependency>
    <groupId>se.alipsa</groupId>
    <artifactId>sourceUrl</artifactId>
    <version>1.0.0</version>
</dependency>

The sourceUrl function is defined as follows:

sourceUrl <- function(url, allowSelfSigned=FALSE, envir=.GlobalEnv) {}

You can use it as follows:

Assuming that the web server has some R code that you want to source at the following location https://somewhere.com/myscript.R.
The content of myscript.R is as follows:

meaningOfLife <- function() {
  42
}

library("se.alipsa:sourceUrl")
sourceUrl("https://somewhere.com/myscript.R")
print(paste("The answer to the ultimate question is", meaningOfLife()))

which will output

[1] "The answer to the ultimate question is 42"
