Dear All, I must be drowning in a glass of water. Consider the following data set
tt2<-structure(list(year = c(2000, 2001, 2002, 2003, 2004, 2005, 2006, 2007, 2008, 2009, 2010, 2011, 2012, 2013, 2014, 2015, 2016, 2017, 2018), country = c("DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE", "DE"), berd = c(35600, 36331.9, 36950, 38029, 38363, 38651.038, 41148, 43034, 46073, 45275, 46929, 51077.2, 53790.1, 53566.2, 56996.5, 60952, 62826, 68644, NA)), row.names = c(NA, -19L), class = c("tbl_df", "tbl", "data.frame"))
I would like to obtain a list of it, where every element of the list contains the subset of tt2 for which year>=2000, year>=2001....year>=2018 etc... It seems something I can tackle with map or map2 from purrr, but so far I am banging my head against the wall. Anyone can help me?
