Module 2 assignment

Task:
Your assignment, evaluate the following function call myMean. The data for this function called assignment.

assignment2 <- c(16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, 22)

>myMean <- function(assignment2) { return(sum(assignment)/length(someData)) }

Ans:
The “assignment2” returned the following:

[1] 16 18 14 22 27 17 19 17 17 22 20 22

The “myMean” returned the following:

Error in myMean(assignment2) : object ‘assignment’ not found

The function myMean does not work the way it was supposed to work because objects “assignment” and “someData” are not defined. If they were both replaced with predefined object “assignment2”, the function “myMean” would return the expected mean value of the given data set.

The corrected program would be:

>assignment2 <- c(16, 18, 14, 22, 27, 17, 19, 17, 17, 22, 20, 22)
>myMean <- function(assignment2) { return(sum(assignment2)/length(assignment2)) }
>myMean(assignment2)

This program will return:

[1] 19.25

Visualization in R

Basic Graph                                                                Romar Wallen For my module 8 visualization I chose the Dow Jones stock market file since I have very little knowledge of it and I'd like to see what the value are and how the values are affected by time. I used this command, DJFranses <- DJFranses[, -1], to remove the first and additional column. This will remove a third element that can issues when running the command for the 2-D graph. running the code below creates a basic visualization of the DJFranses stock market over the 15 year period. plot (DJFranses$time, DJFranses$value, cex = 3, pch = 20, main = "Dow index time series data", xlab="Time", ylab = "Stock Value") Lattice   after loading the library(lattice) into the interface I was able to pl...

  A <- matrix(1:100, nrow=10) > B <- matrix(1:1000, nrow=10) > det(A) [1] 0 > det(B) Error in determinant.matrix(x, logarithm = TRUE, ...) : 'x' must be a square matrix Since the matrix has 1000 values with only 10 rows, that means there’s 100 columns. This forms a non-square matrix, which does not have a determinant. Because of this, there is no inverse for matrix B.
