本文介绍了Rglpk-梦幻足球阵容优化器-For循环输出的绑定的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！
问题描述
我有一个使用Rgplk的梦幻足球阵容优化器.它使用for循环生成多个最佳阵容，其数量由用户输入.代码如下:
I have a fantasy football lineup optimiser using Rgplk. It uses a for loop to generate multiple optimal lineups, the number of which is input by the user. The code is as follows:
Lineups <- list()
for(i in 1:Lineup_no)
{
matrix <- rbind(as.numeric(Data$Position == "QB"), # num QB
as.numeric(Data$Position == "RB"), # num RB
as.numeric(Data$Position == "RB"), # num RB
as.numeric(Data$Position == "WR"), # num WR
as.numeric(Data$Position == "WR"), # num WR
as.numeric(Data$Position == "TE"), # num TE
as.numeric(Data$Position == "TE"), # num TE
as.numeric(Data$Position %in% c("RB", "WR", "TE")), # Num RB/WR/TE
as.numeric(Data$Position == "DEF"),# num DEF
Data$Salary,Data$fpts,Data$Player.Name==Inclusions)
direction <- c("==",">=","<=",">=","<=",">=","<=","==","==","<=","<","==")
opt_var<-Score-0.01
rhs<-c(1,2,4,2,4,1,2,7,1,100000,opt_var,length(Inclusions))
sol <- Rglpk_solve_LP(obj = obj, mat = matrix, dir = direction, rhs = rhs,
types = var.types, max = TRUE)
Lineup<-data.frame(Data[sol$solution==1,])
Lineup<-Lineup[order(Lineup$Position),]
Salary<-sum(Lineup$Salary)
Score<-sum(Lineup$fpts)
print(Lineup)
print(Salary)
print(Score)
Lineups[i]<-Lineup
}
例如，如果我要运行3个最佳阵容，则会得到以下输出:
For example, if I want to run 3 optimal lineups, then I get the following output:
Position Player.Name Team Opponent Salary PPG fpts positionRank upper lower Off_Snaps Pct_Off

在for循环结束时，我想重新排列每个阵容，使其看起来像这样:
At the completion of the for loop I want to rbind each of the lineups so that it looks something like this:
Position Player.Name Team Opponent Salary PPG fpts positionRank upper lower Off_Snaps Pct_Off

1014 WR DeAndre Hopkins Texans Chiefs 14300 16.4 18.8275 4 20.9531 17.3538 73 97%
但是，似乎只有位置"列被添加到了阵容"列表中，而不是每个完整的数据框.
However, only the Position column seems to be getting added to the list Lineups and not each complete dataframe.
[[1]]
[1] "DEF" "QB" "RB" "RB" "RB" "RB" "TE" "WR" "WR"
[[2]]
[1] "DEF" "QB" "RB" "RB" "RB" "RB" "TE" "WR" "WR"
[[3]]
[1] "DEF" "QB" "RB" "RB" "RB" "RB" "TE" "WR" "WR"
我如何更新代码，以便将每个完整的阵容数据框都包含在阵容"列表中，然后将这些阵容绑定在一起以创建如上所示的数据框?
How do I update my code so that each complete lineup dataframe is included in the list Lineups and then subsequently bind together the lineups to create a dataframe like shown above?
推荐答案
我们可以将[更改为[[，以便将for循环中的'Lineup'的值分配给list'Lineups' .另外，最好以所需的长度创建阵容"
We can change the [ to [[ to assign the values of 'Lineup' to the list 'Lineups' in the for loop. Also, it may be better to create the 'Lineups' with the required length
Lineups <- vector("list", length(lineup_no))
for(i in seq_along(Lineup_no)){
...
...
Lineups[[i]] <-Lineup
}
