R create lagged column

I have a data set: set.seed(123) y<-data.frame(week=seq(as.Date("2010-01-03"), I have a zoo object with 4 columns. I want to add a lagged column to every column of the zoo object by adding the name of the column and the"lag_" in front of that. For example if one column, is named "CONS", the lagged column of zoo object should be "lag_CONS". i want this to be done in a loop.

For example, DT[, (cols) := shift(.SD, 1:2), by=id] would lag every column of .SD by 1 and 2 for each group. If .SD contained four columns, the first two elements of the list would correspond to lag=1 and lag=2 for the first column of .SD, the next two for second column of .SD and so on. Please see examples for more. As you can see based on the previous RStudio console outputs, the lead function shifted our vector one element to the right side (i.e. cut off the first value and added an NA at the end) and the lag function shifted our vector one element to the left (i.e. cut off the last value and appended an NA at the beginning).
