A quick script, written in R, to launch API's written using the plumber package for R. Don't forget to 'chmod +x plumberStart.R'. Usage should be 'plumberStart.R /path/to/plumber/file.R <port>', if port is omitted, the script will use 8080 as a default

plumberStart.R

#!/usr/bin/env Rscript
args <- commandArgs(trailingOnly = TRUE)
if (is.na(args[1])) {
        cat('Missing file name\n')
        q('no')
} else {
        file <- args[1]
}
if (is.na(args[2])) {
        cat('No port specified - defaulting to 8080\n')
        port <- 8080
} else {
        port <- as.numeric(args[2])
}
library(plumber)
r <- plumb(file)
r$run(port=port)
