I'm quite new to R. I've been learning R Studio and been working on R Markdown in HTML format. So I apologize in advance if my code seems chaotic.
...Variable_List <- data.frame(..."Method" = c("$$\\bar{x} = \\frac{\\sum{x_i}}{n}$$ where \"$x_{i}$\" is each individual measurement while \"$n$\" is the number of observations.","$$\\sum_{i=1}^{n}(x_{i}-\\bar{x})^{2}$$","$$SS_{xy} = \\sum_{i=1}^{n}(x_{i}-\\bar{x})(y_{i}-\\bar{y})$$","$$\\sigma_{x} = \\sqrt{\\frac{SS_{x}}{n}}$$","$$s_{x} = \\sqrt{\\frac{SS_{x}}{n-1}}$$","$$\\sigma_{xy} = \\frac{SS_{xy}}{n}$$","$$s_{xy} = \\frac{SS_{xy}}{n-1}$$","$$\\rho_{xy} = \\frac{\\sigma_{xy}}{\\sigma_{x}\\sigma_{y}}$$","$$\\hat{y}(x) = \\alpha + \\beta x$$ Where $\\alpha$ and $\\beta$ are constants. Although there are various methods of finding the constants, one method is through matrix regression.<br>Let ${(x_{i},y_{i})}_{i=1}^{n}$ be a range of measurements for two variables, $x$ and $y$.<br> A matrix X for the independent variable $x$ and a vector $\\overrightarrow{y}$ for the dependent variable $y$ can be defined as such:<br>\\begin{bmatrix}1 & x_{1} \\\\ \\vdots & \\vdots \\\\1 & x_{n} \\end{bmatrix} "...),...I know, a lot is going on here, but I need help on this bit at the end:
\\begin{bmatrix}1 & x_{1} \\\\ \\vdots & \\vdots \\\\1 & x_{n} \\end{bmatrix}I tried creating a matrix with the help of atomurl math TeX generator online. I got a matrix going, but apparently there's a new column in between with each row saying "amp;" and I'm confused as to why. I wanted to create a matrix with 2 columns and three rows, where first row has "1" and "x_{1}", second row is a set of \\vdots and last row is "1" and "x_{n}".
Here's a bit of extra code in the same R code block. Could be helpful for anyone who's answering?
Variable_List <- data.frame(Variable_List2, row.names = NULL)kable(Variable_List, format = "html", escape = TRUE, row.names = FALSE, caption = "Table 1.2.1: Variable List") %>% kable_styling( bootstrap_options = c("striped"), full_width = FALSE, position = "center" ) %>% column_spec(1, border_left = "2px solid #ddd") %>% column_spec(2, border_left = "2px solid #ddd", border_right = "2px solid #ddd") %>% column_spec(4, border_left = "2px solid #ddd", border_right = "2px solid #ddd")I tried adding "\" in front, it gave me an error:"! '\&' is an unrecognized escape in character string (:49:8)"I tried writing "&&" instead, it just added an extra column with another "amp;" in each row.I tried writing "&" instead, same output where there's a column of "amp;"'s.
I'm lost.
