我收到例外'System.Runtime.InteropServices.SEHException' in RDotNet.dll
运行一个简单的R脚本:
n + minWidth
使用c#中的代码:
// Load the R environment
REngine.SetEnvironmentVariables();
REngine engine = REngine.GetInstance();
// Load the input data
CharacterVector charVec = engine.CreateCharacterVector(new List<string> { csvFileName });
engine.SetSymbol("input", charVec);
engine.SetSymbol("n", engine.CreateNumeric(numberOfFanfolds));
engine.SetSymbol("minWidth", engine.CreateNumeric(minWidth));
engine.SetSymbol("minScrap", engine.CreateNumeric(minScrap));
engine.SetSymbol("cardboardStep", engine.CreateNumeric(cardboardStep));
// Run the script
results = await Task.Factory.StartNew(() => engine.Evaluate("source('" + script_file_ + "')"));
当我尝试直接运行代码时,它可以正常工作:
var results = await Task.Factory.StartNew(() => engine.Evaluate("n + minWidth"));
这意味着什么?我能做什么?我是否需要以某种方式格式化R脚本?
答案 0 :(得分:0)
只需要重新排列文件路径
script_file_ = scriptFile.Replace("\\", "/");
