How can I upload a csv file to a plumber api in R to get predictions from a model

Question

I have been unsuccessful in finding a way to code a plumber api in R to pass in a csv file of new data and run a saved model to obtain predictions. Any assistance would be greatly appreciated. I have added code for an API which works to input values for each feature and get the prediction I am looking for. I am lost on how to pass in more than just a single record.

load("model.rda")
library(plumber)

#* @apiTitle Prediction
#* Predict number
#* @post /predict/values
function(a, b, c, d){
  #get the df
  newdf <- as.data.frame(list(a  = as.numeric(a),
                              b  = as.numeric(b),
                              c  = as.numeric(c),
                              d  = as.numeric(d)))
  
  #get results of model
  pred <- predict(model_object,newdf)
  pred
}
