小编use*_*067的帖子

我试图在嵌套循环中使用foreach包,但是我的内部循环不识别外部的计数器,我错过了什么？

v3 <- search.compounds.by.mass(100.05,0.5)
foreach(j=2:length(v2)) %:% {
    foreach(i=1:length(v3), .combine=rbind) %dopar% {
        write.table(paste(v3[i], paste(get.reactions.by.compound(v3[i]), collapse=" "), sep=" "), "file1",quote=FALSE, row.names=FALSE, col.names=FALSE, append=TRUE)
        write.table(paste(v3[i], paste(get.pathways.by.compounds(v3[i]), collapse=" "), sep=" "), "file2",quote=FALSE, row.names=FALSE, col.names=FALSE, append=TRUE)
        v3 <- search.compounds.by.mass(v2[j],0.5)
    }
}

我没有网络开发经验，我想用flask为指定字段的表添加数据，这是我的应用程序

from flask import *

from flask import jsonify

app = Flask(__name__)

@app.route('/page_test')                                                                                  
def page_test():
    meas = {"MeanCurrent": 0.05933, "Temperature": 15.095, "YawAngle": 0.0, "MeanVoltage": 0.67367, "VoltageDC": 3.18309, "PowerSec": 0.06923, "FurlingAngle": -0.2266828184, "WindSpeed": 1.884, "VapourPressure": 1649.25948, "Humidity": 0.4266, "WindSector": 0, "AirDensity": 1.23051, "BarPressure": 1020.259, "time": "2015-04-22 20:58:28", "RPM": 0.0, "ID": 1357}
    return jsonify(meas)

if __name__ == "__main__":
    app.run(debug=True)

这是我的 html (templates/view.html)

我有以下功能

fun <- cxxfunction(
    signature(x="numeric", y="numeric",N="interger", w="numeric", p="numeric"), 
    plugin="RcppArmadillo", 
    includes=c("#include <stdlib.h>", "#include <cmath>","#include <numeric>","#include <algorithm>","#include <vector>"), 
    body='
        using namespace Rcpp;
   RNGScope scope;

        NumericVector xa(x);
        NumericVector ya(y);
        int Na = as<int>(N);
        int n_xa = xa.size(), n_ya = ya.size();
        arma::mat wa = Rcpp::as<arma::mat>(w);
        Rcpp::NumericMatrix n(p); //one column to each x[i]/y
        NumericVector limite(n_xa);
        arma::mat z(n_ya, n_xa);
        arma::mat beta(n_ya, n_xa);
        arma::colvec one(xa.begin(), xa.size());
        arma::colvec betaM(ya.begin(), ya.size());
        arma::colvec betaP(ya.begin(), ya.size());
        arma::colvec Prob(ya.begin(), ya.size());
        arma::colvec betaC(ya.begin(), ya.size());
        z.col(0) = arma::zeros<arma::mat>(n_ya, 1);
        NumericVector nV(n_ya);
        NumericVector nT(n_ya);
