Dear all, I have a table like this:
a <- read.csv("test.csv", header = TRUE, sep = ";") a UTM pUrb pUrb_class 1 NF1885 20,160307 NA 2 NF1886 51,965649 NA 3 NF1893 26,009581 NA 4 NF1894 3,141484 NA 5 NF1895 64,296826 NA 6 NF1896 14,174068 NA 7 NF1897 40,985589 NA 8 NF1898 34,054325 NA 9 NF1899 20,657632 NA 10 NF1982 54,712737 NA 11 NF1983 56,016067 NA 12 NF1984 5,977961 NA What I wanted to do is to obtain classified values for "pUrb_class" in relation to "pUrb" as if: pUrb <20 --- pUrb_class = 1 pUrb 20-40 --- pUrb_class = 2 pUrb 40-60 --- pUrb_class = 3 .... Can anyone help me?
