MacOS上F＃中的RProvider错误：无法重现基本示例

Question

running RProvider1.1.20 on a Terminal window on MacOS

I try to run the example from http://bluemountaincapital.github.io/FSharpRProvider/mac-and-linux.html

R.mean([1;2;3;4)] R.x11() R.sin(1)

> R.sin(1.0);;

val it : RDotNet.SymbolicExpression = [1] 0.841471

all work fine

However >R.sin(1.0);; Error in base::sin(0, 1) : 2 arguments passed to 'sin' which requires 1

RDotNet.EvaluationException: Error in base::sin(0, 1) : 2 arguments passed to 'sin' which requires 1

I first wondered if it had to do with regional settings (comma or dot separator for numbers) but the example with 0.1 and 1.0 suggest otherwise

this is a x-post as I also posted this issue in the RProvider GitHub here https://github.com/BlueMountainCapital/FSharpRProvider/issues/186

Answer 1

thanks to @s952163

it IS a regional setting problem. So if your global environment is in English you shouldn't have this bug.

Even though it's not a very satisfying answer, i will mark this as an answer for the time being.
