Play some Ultimate Tic-Tac-Toe?
Description
This function allows one to play the Ultimate version of Tic-Tac-Toe. In the Regular version of Tic-Tac-Toe, players take turns placing their marks, with the objective of achieving three marks in a row in any direction. 9x9 Tic-Tac-Toe or more commonly known as Ultimate Tic-Tac-Toe, adds a twist on the regular version of Tic-Tac-Toe that most of us have come to know. Perceive the board as a big Tic-Tac-Toe board, with the goal being to achieve 3 big marks in any direction. Big marks are achieved by winning the corresponding small Tic-Tac-Toe blocks. The player to move first may play anywhere on the board. However, following moves must correspond to the same big Tic-Tac-Toe block of the small Tic-Tac-Toe board where the last move was played.
Usage
UltimateTicTacToe()
Detects if a certain sequence is present in a matrix.
Description
This function allows for the detection of a particular sequence in a matrix.
Usage
detect_seq(data, sequence, reps, diag = TRUE)
Arguments
data |
A matrix. |
sequence |
The desired sequence to search for. |
reps |
Number of repetitions of the sequence. |
diag |
Do you want to search diagonals? Defaults to TRUE. |
Examples
M = matrix(sample(c(1,2),25,replace=TRUE),5,5)
detect_seq(data = M, sequence = "2", reps = 5)
#or equivalently
detect_seq(data = M, sequence = "22222", reps = 1)
Get all column vectors of a matrix.
Description
This function extracts all column vectors of a matrix and returns the result as a list.
Usage
get_cols(data)
Arguments
data |
Matrix from which to extract column vectors. |
Examples
M = matrix(rnorm(9),3,3)
get_cols(M)
Get all diagonals vectors of a matrix.
Description
This function extracts all diagonal vectors of a matrix and returns the result as a list.
Usage
get_diags(data, direction = "right")
Arguments
data |
Matrix from which to extract diagonal elements |
direction |
Which side to begin on? Takes values of one of "left", "right" or "both". Defaults to "right". |
Examples
M = matrix(rnorm(9),3,3)
get_diags(M)
Get all row vectors of a matrix.
Description
This function extracts all row vectors of a matrix and returns the result as a list.
Usage
get_rows(data)
Arguments
data |
Matrix from which to extract row vectors. |
Examples
M = matrix(rnorm(9),3,3)
get_rows(M)
Get surrounding elements of an element in a matrix.
Description
This function extracts all surrounding elements of a specified element in a matrix and returns the result as a vector.
Usage
get_surround(data, index, type = "all")
Arguments
data |
Matrix. |
index |
Index position of element. Input as a vector of row then column positions. |
type |
Takes values of "direct" and "all". "direct" returns only the elements directly in contact with the specified element, whereas "all" returns every surrounding element including diagonals. Defaults to "all". |
Examples
M = matrix(1:20,4,5)
get_surround(data = M, index = c(2,3))
Converts a matrix index into a sex of x,y coordinates.
Description
This function converts a matrix index into unit x,y plotting coordinates.
Usage
index2xy(data, index)
Arguments
data |
Matrix or data frame. |
index |
A vector of index values. |
Examples
M = matrix(1:20,4,5)
index2xy(data = M, index = c(3,4))
Palindrome checker.
Description
This function checks if the supplied vector is a palindrome (reads the same forwards and backwards).
Usage
is_palindrome(x, case.sensitive = FALSE)
Arguments
x |
Numeric or character vector. |
case.sensitive |
Does upper or lower casing matter? Defaults to FALSE. |
Examples
test1 = 123
test2 = "12321"
test3 = c("a",1,2,3,2,1,"a")
is_palindrome(test1)
is_palindrome(test2)
is_palindrome(test3)
Converts a set of x,y coordinates into a matrix index.
Description
This function converts a set of unit x,y coordinates into a matrix index.
Usage
xy2index(data, x, y)
Arguments
data |
Matrix or data frame. |
x |
x-coordinate |
y |
y-coordinate |
Examples
M = matrix(1:20,4,5)
xy2index(data=M, x=3, y=2)
