There are multiple methods for data splitting in R language, here are two commonly used methods:<\/p>\n

    \n
  1. The subset function can be used to filter subsets of a dataset based on specified conditions. Logical operators (such as greater than, less than, equal to, etc.) and logical expressions (such as AND, OR, NOT, etc.) can be used to create filtering conditions. For example, the following code will filter out observations from the dataset df where the age is greater than or equal to 30 and assign them to a new dataset df_subset:<\/li>\n<\/ol>\n
    df_subset <- subset(df, age >= 30)\r\n<\/code><\/pre>\n
      \n
    1. You can extract specific columns or rows from a dataframe using square brackets [] or dollar sign $ symbols. You can use a logical vector as an index to select observations that meet certain conditions. For example, the following code extracts observations from the dataset df where the age is equal to or greater than 30 years old:<\/li>\n<\/ol>\n
      df_subset <- df[df$age >= 30, ]\r\n<\/code><\/pre>\n
      The above are commonly used data splitting methods in R language, choose a suitable method based on specific needs.<\/p>\n","protected":false},"excerpt":{"rendered":"
