Rplumber-server

A test server powered by R plumber as the first step to convert the model in R script into a knowledge object.

The purpose of this exploratory work is to convert the existing research model in R script into the form of knowledge object and provide the web service API enabled by R package plumber.

Required IDE and R packages

The test server requires RStudio to run.

You can install packages by

• using RStudio UI under Tool -> Install Packages, or,
• using the console command

For example,

install.packages("randomForest")

The following packages are needed to run the R script KO in the test server:

• remote
• jsonlite
• randomForest
• yaml
• survival
• gbm

Additionally, a dev version of plumber is needed for the test server to be able to serve the customized OpenAPI yaml file. To install the dev version, run

remotes::install_github("trestletech/plumber")

start the server

To start the server, go to Rstudio Console and run the command

source("server.R")

A Swagger UI will open in a separate window for you to try the API.

Test Server Routes

The test server mounts three routes, each with one or more endpoints:

• /99999-survival/predict
• /99999-survival/test
• /99999-survival/inputschema
• /hello-world/welcome
• /99999-hepcrf/predict
