Question

我必须将第三方元素集成到我的Angular（4.3.x）应用程序中。他们看起来像：

<any-widget id="123"></any-widget>

我已经通过向app.module.ts添加schemas: [ CUSTOM_ELEMENTS_SCHEMA ]使Angular产生了没有错误。但不幸的是，我不得不做任何事情。我试过了：

<any-widget [id]="id"></any-widget>

和

<any-widget id="{{id}}"></any-widget>

但是根本没有显示id。知道如何使这项工作吗？

Answer 1

#first install spatstat, maptools y sp

#load them

library(spatstat)
library(maptools)
library(sp)


#create an array of folders, will add more when everything works fine
folders=c("20170518")
for(f in folders){

  #read all shp from that folder, both points and tracks
  pointfiles <- list.files(paste("./",f,"/points", sep=""), pattern="*.shp$")
  trackfiles <- list.files(paste("./",f,"/tracks", sep=""), pattern="*.shp$")

  #for each point and track couple
  for(i in 1:length(pointfiles)){


    #create a linnet object with the track

    t<- as.linnet(rgdal::readOGR(paste("./",f,"/tracks/",trackfiles[i], sep="")))
    #plot(t)



    #create a ppp object for each set of points

    pre_p<-rgdal::readOGR(paste("./",f,"/points/",pointfiles[i], sep=""))
    #plot(p)
    #obtain the coordinates the current set of points
    c<-coordinates(pre_p)
    #create vector of x coords
    xc=c()
    #create vector of y coords
    yc=c()
    #not a very good way to fill my vectors but it works for my study area
    for(v in c){
      if(v>4000000){yc<-c(yc,v)}
      else {if(v<4000000 && v>700000){xc<-c(xc,v)}}
    }
    print(xc)
    print(yc)
    #create a ppp object using the vectors of x and y coords, and a window object
    #extracted from my set of points
    p=ppp(xc,yc,Window(as.ppp(pre_p)))

    #join them into an lpp object

    pt <- lpp(p,t)
    #plot(pt)

    #analize it with the linearK function, nsim=9 for testing purposes
    #envelope.lpp is the method for analyzing linear point patterns
    assign(paste("results",f,i,sep="_"),envelope.lpp(pt, nsim=9, fun=linearK))

  }#end for each points & track set
}#end for each day of study

或

<any-widget [attr.id]="id"></any-widget>

没有<any-widget attr.id="{{id}}"></any-widget> Angular尝试绑定到HTML元素的属性或Angular指令的attr.。如果使用的名称都不存在，则需要使用属性绑定。
