I have a csv dataset that has date of births stored as characters in the format - 01-06-68("%d-%m-%y"). I tried to convert the dates to Date objects using as.Date() but it identifies the year as 2068 when in fact the year is 1968. I understand Date starts from 1970-01-01 in R, is there an easy fix to this?
I am using the lubridate package to find the age. Some age were negative due to the wrongly identified year.
elapsed <- train$Date.of.Birth %--% Sys.Date()
train$age <- floor(as.duration(elapsed) / dyears(1))
