Thank you. I have tried that but the problem is i have 53 weeks for some years. thats why im seeking options to read my data directly into year week. Is there any possibility for that?
I have attached my data frame here
Mydf<-structure(list(YearWeek = c("201901", "201902", "201903", "201904",
"201905", "201906", "201907", "201908", "201909", "201910", "201911",
