问题:

I am writing a bunch of math equations in R Markdown inside Rstudio. And I want to align the content either to the left or center. However, seems like the align will align them to the right as default.

I did some google and some of them told me to use a package called ragged2e, but it did not work when I added it in. I am wondering if this should be a latex question or rmarkdown question.

I'm not quite sure what you're going for here, but line breaks, \\ go at the end of tthe line, not the beginning, and the aligmnent operator is &. So this:

$$
\begin{aligned}
 AR(p): Y_i &= c + \epsilon_i + \phi_i Y_{i-1} \dots \\
 Y_{i} &= c + \phi_i Y_{i-1} \dots
\end{aligned}
$$

produces this:

left align the formula

$\begin{aligned}
AR(p): Y_i &= c + \epsilon_i + \phi_i Y_{i-1} \dots \\
Y_{i} &= c + \phi_i Y_{i-1} \dots
\end{aligned}$

&...& show in the line ; $$...$$ display out;

Wow. That works great! Thank you for the help! This worked perfectly in R Studio Markdown. My code was in an ordered list and is as follows:

$\begin{aligned}
    \lim_{x \to \infty}\frac{2x-5}{4x^4}=0\\
    \end{aligned}$    

$\begin{aligned}
    \frac{d}{dx}\left( \int_{0}^{x}f(u)\,du\right)=f(x)\\
    \end{aligned}$
