7: Matrices and Data Frames

• matrices and dataframes are (2-dimensional) tabular data types - data with rows and columns
• matrices can only contain a single class of data, while data frames can consist of many different classes of data
• dim() function, to get OR set the dim attribute for an R object
• attributes() function
• class() function
• matrix() function, to create matrices
• data.frame() function, to create data frames
• cbind() function, to combine columns
• colnames() function, to set the colnames attribute

8: Logic

• logical (boolean) values: TRUE and FALSE
• logical operators:
  • ==, <, <=, >, >=, !=
  • ! NOT operator negates logical expressions (!TRUE, !FALSE)
  • &, && AND operators, TRUE if both operands are TRUE
  • |, || OR operators, TRUE if one of the operands is TRUE
• functions to deal w/ logical expressions:
  • isTRUE()
  • xor() (exclusive OR) - If one argument evaluates to TRUE and one argument evaluates to FALSE, then this function will return TRUE, otherwise it will return FALSE. xor(TRUE, TRUE) evaluates to FALSE.
  • which(), any() , all()

Complete swirl module '12: Looking at Data' and submit your successful completion via email (domenico.giusti@uni-tuebingen.de)

swirl modules won't count towards your final grade but it is highly recommended to complete them - the topics covered in the swirl modules will be on the final exam.

Pull requests help you collaborate on code with other people. Pull requests let you tell others about changes

• you've pushed to a branch in a repository on GitHub
• you've made to a fork of an upstream repository.

Once a pull request is opened, you can discuss and review the potential changes with collaborators and add follow-up commits before your changes are merged into the base branch.
