我有一个列表,例如它的第二个元素是:
SELECT IssuerLS, Issuer, Ticker, SUM (GLPeriod) As [PNL], ReportDate,
CAST(SUM (GLPeriod)/(SELECT Nav AS NavBOM
FROM Portfolio.DailyStats ds
WHERE Date = (SELECT CONVERT(CHAR(10),DATEADD(dd,-(DAY(GetDate())-1),GetDate()), 120)))
AS Decimal (7,4)) AS[%ofNAV]
FROM Portfolio.DailyPortfolioIssuerLS
WHERE ReportDate BETWEEN
(SELECT CONVERT(CHAR(10),DATEADD(dd,-(DAY(GetDate())-1),GetDate()),120))
AND
(SELECT CONVERT(CHAR(10),(getdate()),120))
GROUP BY Issuer, Ticker, IssuerLS, ReportDate
我尝试将列表的第二个元素转换为代码datf[2]
[[1]]
topicML gender
"0" "male"
sentiment topicV
"0" "0"
的数据框,但它不起作用,因为列表不正确,因此代码可以工作。
因此,正如我们所见,列表的每个元素都是文本,我想将其转换为具有以下结构的数据框:
a <- as.data.frame(datf[2])
我该怎么做?
答案 0 :(得分:0)
您可以尝试以下方法:
public FeedAdapter(Context context, List<ParseObject> yeets) {
super();
mYeets = yeets;
mContext = context;
this.adapter = this;
profilePictureImageLoader = new ImageLoader(new ProfilePictureFileCache(mContext));
}
