Functions

hw04ptwyunting package includes two functions.
1. myseq_n()
2. numSeqPlot()

Examples

myseq_n()

• The recursive sequence defined by:

• myseq_n() needs two inputs, the first is a vector x containing the first three numbers of this sequence. The second one is a positive (>0) integer n which represents the final nth element in the sequence to calculate.

• This is a basic example which shows you how to use myseq_n() function:

library(hw04ptwyunting)
myseq_n(x = c(2, 3, 3), n = 3)
#> [1] 3
myseq_n(x = c(2, 4, 3), n = 4)
#> [1] 2.5
myseq_n(x = c(2, 4, 3), n = 5)
#> [1] 2.7
myseq_n(x = c(2, 4, 3), n = 6)
#> [1] 2.783333
myseq_n(x = c(2, 4, 3), n = 7)
#> [1] 2.754762

numSeqPlot()

This function numSeqPlot() shows a line graph that plots the relation between first three columns and fourth column.
- The prerequisite is this data frame must have four columns.
- The first three columns are the values of the three numeric to be input, and the fourth column is the positive integer n for the sequence to be generated.
- numSeqPlot() should return a line plot of the output values for the different values of n. This graph shows the output of x-axis is called n with input of fourth column, the output of y-axis is called output with the first three terms in the sequence.
- This is a basic example which shows you how to use numSeqPlot() function:

# testing the function
my_data <- tibble::tribble(
  ~x, ~y, ~z, ~n,
  2,4,3,3,
  2,4,3,4,
  2,4,3,5,
  2,4,3,6,
  2,4,3,7,
  2,4,3,8,
  2,4,3,9,
  2,4,3,10,
  2,4,3,12)

# numSeqPlot(my_data)
