我正在尝试读取CSV文件并将其更改为XTS格式.但是,我遇到了CSV格式,并且在单独的列中有日期和时间字段.
2012.10.30,20:00,1.29610,1.29639,1.29607,1.29619,295
2012.10.30,20:15,1.29622,1.29639,1.29587,1.29589,569
2012.10.30,20:30,1.29590,1.29605,1.29545,1.29574,451
2012.10.30,20:45,1.29576,1.29657,1.29576,1.29643,522
2012.10.30,21:00,1.29643,1.29645,1.29581,1.29621,526
2012.10.30,21:15,1.29621,1.29644,1.29599,1.29642,330
我试图把它拉进来
euXTS <- as.xts(read.zoo(file="EURUSD15.csv", sep=",", format="%Y.%m.%d", header=FALSE))
但它给了我这个警告信息,所以我想我不得不附上时间戳,但我不确定最好的方法.
Warning message:
In zoo(rval3, ix) :
Some methods for “zoo” objects do not work if the index entries in ‘order.by’ are not unique
