How to Use a Script or Functionquire specific kinds of arguments, which must be input into the function correctly. For example, if a function calls for a matrix and a data.frame is input, the function will return an error. Since external tables are often read into the R workspace as data.frames, using a data.frame for a matrix is作者: Expressly 時間: 2025-3-22 19:13

The R Prompt and the R Studio WindowsThis chapter covers the R prompt and the R Studio windows. It starts with descriptions of the three parts of R: objects, operators, and assignments. It continues with a discussion of working with the R prompt, followed by an example of doing a calculation at the R prompt. Afterward, it describes the four R Studio windows.作者: interior 時間: 2025-3-27 15:21 作者: arcane 時間: 2025-3-27 21:08 作者: ARM 時間: 2025-3-28 01:10
Descriptive Functions and Manipulating ObjectsFor arrays, matrices, vectors, lists, and expressions, in command line R, there are a number of functions that describe various attributes of an object.
