我是R的新手，最近，我在tsDyn包中使用了NNET函数，当我同时加载两个包update和// value coming from website
var obj = {
"regionId" : 3526,
"regionName" : "So Cal",
"categories" : [
"Other",
"Seeds",
"Tincture",
"Cannabis",
"Edibles",
"Extracts",
"Prerolled",
"Vape Cartridges"
]
}
> db.drugs.insert(obj);
> db.drugs.find({regionId: obj.regionId}).pretty();
{
"_id" : ObjectId("5aa3ba064a7f0d521aa4dacb"),
"regionId" : 3526,
"regionName" : "So Cal",
"categories" : [
"Other",
"Seeds",
"Tincture",
"Cannabis",
"Edibles",
"Extracts",
"Prerolled",
"Vape Cartridges"
]
}
// assuming the category changes
// push adds an element to categories
> obj.categories.push("concain");
> db.drugs.update( { regionId: obj.regionId }, obj );
> db.drugs.find({regionId: obj.regionId}).pretty()
{
"_id" : ObjectId("5aa3ba064a7f0d521aa4dacb"),
"regionId" : 3526,
"regionName" : "So Cal",
"categories" : [
"Other",
"Seeds",
"Tincture",
"Cannabis",
"Edibles",
"Extracts",
"Prerolled",
"Vape Cartridges",
"hello"
]
}
// remove hello from the categories
> obj.categories.pop();
> db.drug.update( { regionId: obj.regionId }, obj );
> db.drugs.find({regionId: obj.regionId}).pretty();
{
"_id" : ObjectId("5aa3ba064a7f0d521aa4dacb"),
"regionId" : 3526,
"regionName" : "So Cal",
"categories" : [
"Other",
"Seeds",
"Tincture",
"Cannabis",
"Edibles",
"Extracts",
"Prerolled",
"Vape Cartridges"
]
}
时，我运行时出错了包tidyquant中的示例代码。我不知道如何解决这个问题。
tsDyn错误：
tsDyn必须是向量，而不是ts对象，是否需要library(tidyquant) library(tsDyn) mod.nnet <- nnetTs(log(lynx), m=2, size=3) mod.nnet？
