In R language, various functions can be used to read and import different types of data files. Here are some commonly used methods:<\/p>\n

    \n
  1. Import data from a CSV file into R.<\/li>\n<\/ol>\n
    data <-<\/span> read.csv(<\/span>\"file.csv\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
      \n
    1. xl read<\/li>\n
    2. import the function read_excel()<\/li>\n<\/ol>\n
      library(<\/span>readxl)<\/span>\r\ndata <-<\/span> read_excel(<\/span>\"file.xlsx\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Read lines.<\/li>\n<\/ol>\n
        data <-<\/span> readLines(<\/span>\"file.txt\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
          \n
        1. originating from another country<\/li>\n
        2. Open the SPSS file for reading.<\/li>\n<\/ol>\n
