我正在尝试使用该RNeo4j包在 R 中创建一个图形数据库。基本上，@Nicole White 在这里展示的是我试图完全通过 RStudio IDE 实现的目标。我已将数据读入 R 并使用lubridate包对日期字段进行了一些基本的管理。此后，我将关注 Nicole 在此处为hflights数据集显示的内容。这是相关代码：

query="
CREATE (complaint:Complaint {id: TOINT({ComplaintID})})
SET complaint.day = ({ComplaintDay}),
    complaint.month = ({ComplaintMonth}),
    complaint.year = ({ComplaintYear})
MERGE (company:Company {name:{CompanyName}})
MERGE (response:Response {name:{Companyresponsetoconsumer}})

CREATE (complaint) -[:AGAINST]-> (company)
CREATE (response) -[r:TO]-> (complaint)

SET r.timely = CASE {Timelyresponse} WHEN 'Yes' THEN true ELSE false END,
    r.disputed = CASE {Consumerdisputed} WHEN 'Yes' THEN true ELSE false END


"

tx = newTransaction(graph)

for(i in 1:nrow(complaint)) {
  row = complaint[i, ]
  appendCypher(tx, query,
               ComplaintID=complaint$Complaint.ID,
               ComplaintDay=complaint$Complaint.Day,
               ComplaintMonth=complaint$Complaint.Month,
               ComplaintYear=complaint$Complaint.Year,
               CompanyName=complaint$Company,
               Companyresponsetoconsumer=complaint$Company.response.to.consumer,
               Timelyresponse=complaint$Timely.response.,
               Consumerdisputed=complaint$Consumer.disputed.)
}
commit(tx)

summary(graph)

但是，当我运行for循环时，出现以下错误：

Error in appendCypher.transaction(tx, query, ComplaintID = 

complaint$Complaint.ID,  : 
  Neo.ClientError.Statement.TypeError

状态码表明该complaint$Complaint.ID类型可能不受支持。但是不会TOINT管这个吗？

请在这里提供一些帮助。

for循环中的一个非常愚蠢的错误。这是有效的：

for(i in 1:nrow(complaint)) {
  row = complaint[i, ]
  appendCypher(tx, query,
               ComplaintID=row$Complaint.ID,
               ComplaintDay=row$Complaint.Day,
               ComplaintMonth=row$Complaint.Month,
               ComplaintYear=row$Complaint.Year,
               CompanyName=row$Company,
               Companyresponsetoconsumer=row$Company.response.to.consumer,
               Timelyresponse=row$Timely.response.,
               Consumerdisputed=row$Consumer.disputed.)
}
