}示例2: GenetateLatencyVsMessageLengthPlot_RScript
static void GenetateLatencyVsMessageLengthPlot_RScript(REngine engine, string latencyCsvFilename)
{
//For formatting purposes, make sure the filename is acceptable for R function read.csv
string fileToReadFromCommand = latencyCsvFilename.Replace(@"\", @"/");
//Convert to R character vector
CharacterVector cvFilename = engine.CreateCharacterVector(new[] { fileToReadFromCommand });
// and assign it to variable (in R engine) called fileToReadFrom
engine.SetSymbol("fileToReadFrom", cvFilename);
//And then evaluate the script - this uses the 'fileToReadFrom' in a read.csv call
engine.Evaluate(MyRDotNetApplication.Properties.Resources.latencyVsMessageLengthScatterPlot); //R-Script to generate plot
