我正在尝试绘制滚动线性回归,但出现以下错误:
if (any(by < 0L) || any(by > nc)) stop("'by' must match numbers of columns") 中的错误:需要 TRUE/FALSE 的地方缺少值
相关代码为:
library(TTR)
mydata <-read.csv("EURUSD2.csv", sep=",",header=TRUE)
gh<-as.matrix(mydata)
reg <- rollSFM(mydata[, "PRICE"], 1:nrow(mydata), n=5)
这是 CSV 文件的示例:
BAR,PRICE,HIGH,LOW
0,113.3035,113.306,113.282
1,113.306,113.311,113.296
2,113.306,113.312,113.302
3,113.297,113.308,113.297
4,113.2875,113.304,113.285
5,113.2975,113.298,113.29
6,113.278,113.303,113.278
7,113.2915,113.294,113.28
8,113.3,113.3,113.284
9,113.298,113.302,113.296
10,113.3195,113.32,113.3
11,113.3275,113.336,113.32
为什么它不接受这些数据?
