r; opencpu won't start

Question

I am installing opencpu on a new windows 10 box. It already runs on two other windows machines.

The library is found but opencpu is not recognized as an object, so the server does not start

> library(opencpu)

Loading config from C:/Users/jake_000/Documents/R/win-library/3.3/opencpu/config/defaults.conf 

Loading config from C:\Users\jake_000\AppData\Local\opencpu\opencpu/user.conf
Welcome to OpenCPU!




> opencpu$start(9831)
Error: object 'opencpu' not found

Can anyone suggest what is going wrong here? Hopefully, this is basic human error, but I am at a loss.

The [GitHub page](https://github.com/opencpu/opencpu) suggests you run `ocpu_start_server(9831)`. — r2evans, Jun 01 '17 at 03:48
that did the trick. Any idea why the one box allowed opencpu$start and the other didn't? — Jake, Jun 01 '17 at 03:59

It seems Jeroen has recently changed from using opencpu$start() to ocpu_start_server(). From the readme:

To start the single-user development server in R:
library(opencpu)
ocpu_start_server()
Or to start an App:
ocpu_start_app("rwebapps/stocks")

As to why you see different behavior between servers, my guess is you (or someone) did a devtools::install_github("opencpu/opencpu") more recently on one server than the other.
