I am trying to set u a limit for my plot window according to the range of a year column I have. The first year in the range is just simply the first row, referred to as data$year[1]. How can I find the last row in a similar way to set the last year in the range? What I want to accomplish is the following: "plot(....,xlim = c(data$year[1], data$data[lastrow]),...)", is this possible? --
