您好我使用以下代码生成使用晶格的xyplot

xyplot(Rate~Weight|Temp, groups=Week, rate,
 pch=c(15,16,17,3), col=c("blue","red","green","purple"),
 as.table=TRUE,
 xlab="Weight (gr)", ylab="Rate (umol/L*gr)",
 main="All individuals and Treatments at all times",
 strip=strip.custom(strip.names=1),
 key=
 list(text=list(c("Week","1","2","6","8")),
 points=list(pch=c(NA,15,16,17,3),col=c(NA,"blue","red","green","purple")),
 space="right")
 )

这给了我以下情节:

现在更改代码后按照建议包含面板顺序:

xyplot(Rate~Weight|Temp, groups=Week, rate,
 index.cond=list(c(4,1,2,3)),#this provides the order of the panels
 pch=c(15,16,17,3), col=c("blue","red","green","purple"),
 as.table=TRUE,
 xlab="Weight (gr)", ylab="Rate (umol/L*gr)",
 main="All individuals and Treatments at all times",
 strip=strip.custom(strip.names=1),
 key=
 list(text=list(c("Week","1","2","6","8")),
 points=list(pch=c(NA,15,16,17,3),col=c(NA,"blue","red","green","purple")),
 space="right")
 )

我们得到了正确的订单

谢谢您的帮助

我是 Postman 的新手，遇到了一个我无法弄清楚的反复出现的问题。我试图使用在预请求脚本上建立的数据数组多次运行相同的请求，但是，当我去运行程序时，请求只运行一次，而不是 3 次。

预请求脚本：

var uuids = pm.environment.get(“uuids”);

if(!uuids) {
uuids= [“1eb253c6-8784”, “d3fb3ab3-4c57”, “d3fb3ab3-4c78”];
}

var currentuuid = uuids.shift();
pm.environment.set(“uuid”, currentuuid);
pm.environment.set(“uuids”, uuids);

测试：

var uuids = pm.environment.get(“uuids”);

if (uuids && uuids.length>0) {
postman.setNextRequest(myurl/?userid={{uuid}});
} else {
postman.setNextRequest();
}

我查看了有关文档，但找不到我的代码有什么问题。

谢谢！

我有以下条形图,我想添加错误栏.

library(lattice)    
barchart(Change~fTreat,groups=Process,change,
          auto.key=list(points=FALSE,rectangles=TRUE),
          panel=function(x, y,...){
            panel.barchart(x,y,origin = 0,...);
            panel.abline(h=0,col="black",...);
            }
          )

我已经尝试使用memisc包中的panel.errbars,它对xyplots非常有用,但是当我将它添加到我的代码时它不尊重这些组.

library(memisc)    
barchart(cbind(Change,lower,upper)~fTreat,groups=Process,change,
     ylab="Pocertage change",
     ylim=-115:50,
     scales=list(alternating=FALSE,
                 tick.number=7,
                 tck=c(-1,0)),
     panel=function(x, y,groups,...){
       panel.barchart(x,y=change$Change,groups=change$Process,origin = 0,...);
       panel.abline(h=0,col="black",...);
       panel.errbars(x,y,make.grid="none",ewidth=0.2,type="n",...)
     }
     )

有关如何使用panel.errbars或任何其他功能向我的绘图添加错误栏的任何想法？
