R secure coding

January 13, 2024

Secure Programming is an important part of a software developers job and for my BMI reader I've updated and working on more secure programming paradigms or methods not limited to integrating packages like openssl and auditor. Meanwhile I've already included secure coding packages that R offers like testthat (). gsub () is a secure programming tool in R that helps perform crucial data security and sanitization functions w1 = 0; w2 = 0; w3 = 0; w4 = 0; w5 = 0; w6= 0; h=0; avgw = 0; SP = 0; DP = 0; PP=0; h = readline("Enter your height value: "); w1 = readline("Enter first Weight value: "); w2 = readline("Enter second Weight value: "); w3 = readline("Enter third Weight value: "); w4 = readline("Enter fourth Weight value: "); w5 = readline("Enter fifth weight value: ");w6 = readline("Enter sixth Weight value: "); w1 = as.numeric(w1); w2 = as.numeric(w2); w3 = as.numeric(w3); w4 = as.numeric(w4); w5 = as.numer...

Mod 11 debugging

November 05, 2023

Debugging this R program. Steps taken. running the program. The R programming environment output an Error message. The error as seen below. Reformating the program using an editor that can really help readability and run time. To correct the error. reformatting of key words, Correct spacing and alignment of iterations statements, for loops, and output: return helped the program to compile smoothly without error > tukey_multiple <- function(x) { + outliers <- array(TRUE,dim=dim(x)) + for (j in 1:ncol(x)) + { + outliers[,j] <- outliers[,j] && tukey.outlier(x[,j]) + } + outlier.vec <- vector(length=nrow(x)) + for (i in 1:nrow(x)) + { outlier.vec[i] <- all(outliers[i,]) } return(outlier.vec) } Error: unexpected symbol in: " for (i in 1:nrow(x)) { outlier.vec[i] <- all(outliers[i,]) } return" > tukey_multiple <- function(x) { + + > tukey_multiple <- function(x) + + { + + ou...

Final Project-R Package

Introduction BMI/BP Calculator My biological father suffered a stroke 4 years ago , however, I am not here to lament on his medical condition but to provide a solution, to be more precise, a preventative measure for physical trainers ( which I believe play a important role in professional spheres) or any for that matter. This tool can help someone quickly figure out the next best course of actions regarding there medical health, and body weight, if there are any concerns to report. The calculator output the value of your cardiac output, which is the volumetric flow rate, Q . The optimum value is 40 L/m. Recording this value we can calculate Mean Arterial Pressure (MAP). MAP is the product of cardiac output and total peripheral vascular resistance . Importantly, both of these parameters are under the control of the arterial baroreflex and autonomic nervous system. Since cardiac output is the product of heart rate and stroke volume, changes in either of these parameter...
