In R language, data can be imported using the following methods:<\/p>\n

    \n
  1. Import a text file using the read.table() function, for example:<\/li>\n<\/ol>\n
    data <-<\/span> read.table(<\/span>\"data.txt\"<\/span>,<\/span> header =<\/span> TRUE<\/span>)<\/span>\r\n<\/code><\/pre>\n
      \n
    1. Importing a CSV file using the read.csv() function, for example:<\/li>\n<\/ol>\n
      data <-<\/span> read.csv(<\/span>\"data.csv\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
        \n
      1. Before using the read.xlsx() function to import an Excel file, you need to first install the readxl package, for example:<\/li>\n<\/ol>\n
        install.packages(<\/span>\"readxl\"<\/span>)<\/span>\r\nlibrary(<\/span>readxl)<\/span>\r\ndata <-<\/span> read_excel(<\/span>\"data.xlsx\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
          \n
        1. Import R data files using the readRDS() function, for example:<\/li>\n<\/ol>\n
          data <-<\/span> readRDS(<\/span>\"data.rds\"<\/span>)<\/span>\r\n<\/code><\/pre>\n
            \n
          1. Functions can be used to import data in various specific data formats, for example, the fromJSON() function in the jsonlite package can be used for JSON files, and the read_xml() function in the XML2 package can be used for XML files.<\/li>\n<\/ol>\n
            After importing data, you can view basic information about the data using functions such as print() and summary(), or directly analyze and visualize the data.<\/p>\n","protected":false},"excerpt":{"rendered":"
