无法在R中写入数字数据(包事件研究)

无法在R中写入数字数据(包事件研究),r,numeric,R,Numeric,我在举一些例子。()这是我的firmData,而不是从Yahoo获取数据 code date value KS233740Equity 05.12.2016 7225 KS233740Equity 07.12.2016 7235 KS233740Equity 06.12.2016 7355 KS233740Equity 08.12.2016 7395 KS233740Equity 02.12.20

导入时,
为.numeric(firmData$value)=true
。但当我想以特定的方式将其传输到csv文件时,这似乎变成了非数字

library(dplyr)
firmData %>% 
  dplyr::select(code, date, value) %>%
  dplyr::mutate(date = format(date, "%d.%m.%Y"))        # this is for this specific code
  readr::write_delim(path      = "02_firmDataPrice.csv", 
                     delim     = ";", col_names = F)


library(EventStudy)
key <- "573e58c665fcc08cc6e5a660beaad0cb"
est <- EventStudyAPI$new()
est$authentication(apiKey = key)
esaParams <- EventStudy::ARCApplicationInput$new()
esaParams$setResultFileType("csv")
esaParams$setBenchmarkModel("garch")

dataFiles <- c("request_file" = "01_requestFile.csv",
               "firm_data"    = "02_firmDataPrice.csv",
               "market_data"  = "03_marketDataPrice.csv")

EventStudy::checkFiles(dataFiles)

我最终使用了他们提供的Eviews加载项,

如果您需要做的只是将数字从class
字符转换为class
数字,请尝试以下代码

首先,您有字符,因为您的数据集
请求
是类
矩阵
的对象,并且在R矩阵中只能保存一种类型的数据。因此,将矩阵强制为
data.frame
。然后
lappy
将函数
as.numeric
添加到相应的列中

request <- as.data.frame(request, stringsAsFactors = FALSE)
request[6:9] <- lapply(request[6:9], as.numeric)
request
#  V1             V2        V3         V4    group  V6 V7  V8  V9
#1  1 KS233740Equity indexData 04.04.2018 leverage -10 10 -11 250
#2  2 KS233160Equity indexData 04.04.2018 leverage -10 10 -11 250
#3  3 KS278240Equity indexData 04.04.2018    Other -10 10 -11 250

您能否在问题中发布
dput(head(request,10))
dput(head(market_data,10))
的输出?此外,请参见@Rui Barradas,
dput(head(request,5))=结构(c(“1”、“2”、“3”、“KS233740Equity”、“KS233160Equity”、“KS278240 equity”、“indexData”、“indexData”、“indexData”、“indexData”、“04.04.2018”、“04.04.2018”、“04.04.2018”、“杠杆”、“杠杆”、“其他”、“10”、“10”、“10”、“11”、“11”、“11”、“250”、“250”)、.Dim=c(3L,9L),.Dimnames=list(NULL,c(“,”,“,”,“,”组“,”组“,”组“,”组“,”组“,”组“,”组“,”组“,”数据头(市场数据,5))=structure(list)(value=c(889.2882.36895.21903.64903.01),code=structure(c(1L,1L,1L,1L),.Label=“KOSDAQ150”,class=“factor”),date=structure(c(1357084800,1357171200,1357257600,1357516800,1357603200),class=c(“POSIXct”,“POSIXt”),tzone=“UTC”),.Names=c(“value”,“code”,“date”),row.Names=c(“2013-01-02”,“2013-01-03”,“2013-01-04”,“2013-01-07”,“2013-01-08”),class=“data.frame”)
