Hello, My programming is as follows.
library(highfrequency) library(data.table) library(xts) tm<-seq.POSIXt(from = as.POSIXct("2020-08-20 09:30:00"),to = as.POSIXct("2020-08-20 15:59:00"),by='min') data<-xts(x=data$PRICE,order.by=tm) data <- as.data.table(data) setnames(data,c('index'),c('DT')) setnames(data,c('V1'),c('PRICE')) LMtest <- intradayJumpTest(pData = data,volEstimator = "RM", driftEstimator = "none",RM = "bipower", lookBackPeriod = 20,on = 'minutes', k = 5, marketOpen = "09:30:00",marketClose = "15:59:00") plot(LMtest) However, the error is that ''Error in xy.coords(x, y, setLab = FALSE) : 'x' and 'y' lengths differ''. I don't know how to correct it.
