Hi experts, I want to user haar wavelet transform. If I am using this simple command, it works nice: k<-c(1,2,3,4,5,6,7,8) ywd<-wd(k,filter.number=1,family="DaubExPhase") but if the K is a list like this: *[[1]]* *[1] 401* * * *[[2]]* *[1] 481* * * *[[3]]* *[1] 480* * * *[[4]]* *[1] 482* * * *[[5]]* *[1] 395* *...* * * it doesnt work and I get this error: Error in wd(k, filter.number = 1, family = "DaubExPhase") : * Data is not atomic* * * how can I solve this problem?how can I convert this list to a normal list?
