VS中使用QT调用R脚本

　　一开始想直接把R编译成库然后调用R，后来查了n多资料，发现VS中是无法办到的，官方也给出了一句话，大概意思就是没可能在VS中使用R提供的C++接口，大概是涉及到了底层的ABI的原因，具体也不太清楚。

　　于是就想到了直接采用新建文件然后写成.R脚本的方式来调用R，这种使用方式必须安装R，然后从程序内部调用RScript.exe以及相应脚本。

QFile Rfile("C:\\temp\\RScript\\heatmap.R");

            Rfile.open(QIODevice::WriteOnly);

            QTextStream RfileWrite(&Rfile);

            RfileWrite << "library(RColorBrewer)" << endl;

            RfileWrite << "library(gplots)" << endl;

            RfileWrite << "x = read.table(\"C:\\\\temp\\\\RData\\\\heatmap.dat\", header = TRUE, sep=\"\t\")" << endl;

            RfileWrite << "mat = data.matrix(x)" << endl;

            RfileWrite << "png(file = \"C:\\\\temp\\\\RPic\\\\heatmap.png\", bg = \"transparent\")" << endl;

            RfileWrite << "heatmap.2(mat, Rowv = TRUE, Colv = TRUE,  distfun = dist,hclustfun = hclust,\

xlab = \"X data\", ylab = \"Y data\",\

key = TRUE,\

keysize = 2,\

trace = \"none\",\

density.info = c(\"none\"),\

margins = c(5, 5),\

col = brewer.pal(10, \"PiYG\")\

)"<<endl;

            RfileWrite << "dev.off()" << endl;

            Rfile.flush();

            Rfile.close();

            //system("C:\\\"program files\"\\R\\R-3.1.2\\bin\\RScript D:\\drawtest.R");

            //system("RScript D:\\drawtest.R");

            ShellExecuteA(NULL, "open", "RScript.exe", "C:\\temp\\RScript\\heatmap.R", NULL, SW_HIDE);
