Question

如果有人明白下面粗体句的含义，请帮助我理解这意味着什么？它来自Ipfp函数的R文档。（https://www.rdocumentation.org/packages/mipfp/versions/3.1/topics/Ipfp）

＆＃34; target.list - target.data中边际目标约束的维度列表。 列表的每个组件都是一个数组，其单元格指示相应边距与哪个维度相关。

＆＃34; target.data - 包含目标边际表数据的列表。列表的每个组件都是一个存储边距的数组。列表顺序必须遵循target.list中定义的顺序。请注意，数组的单元格必须是非负数。＆＃34;

作为一个例子，让我们说我有这张表：

seed.ex <- array(1,dim=c(3,4))
seed.ex
     [,1] [,2] [,3] [,4]
[1,]    1    1    1    1
[2,]    1    1    1    1
[3,]    1    1    1    1

这些目标存储在＆＃39; target.data＆＃39;：

中

target.row <- c(50,50,100)
target.col <- c(50,50,50,50) 
tgt.data.ex <- list(target.row, target.col)

我应该如何指定＆＃39; target.list＆＃39;？

tgt.list.ex <- list(?,?)

那将进入Ipfp功能......

res.ex <- Ipfp(seed.ex, tgt.list.ex, tgt.data.ex, print = TRUE, iter = 1000)

Answer 1

我非常确定答案是list(1,2)。我从来没有使用过这个软件包，但是使用二维种子的两个例子都有这个答案。这是我的考试：

tgt.list.ex <- list(1,2)
