What's the correct way to do this? thanks. I'd also appreciate the

问题 I am trying to create a column in a data.frame or data.table with two conditions. The difference to the posts I have seen and which I have tried to modify below is that I do not have 'value' for the conditions but the conditions depend on other variables in the data.frame . Let's assume this is my data frame: mydf <- data.frame (Year = c(2000, 2001, 2002, 2004, 2005, 2007, 2000, 2001, 2002, 2003, 2003, 2004, 2005, 2006, 2006, 2007), Name = c("Tom", "Tom", "Tom", "Fred", "Gill", "Fred", "Gill"
