Short Paper
In rticles: Article Formats for R Markdown

Please make sure that your manuscript follows the guidelines in the Guide for Authors of the relevant journal. It is not necessary to typeset your manuscript in exactly the same way as an article, unless you are submitting to a camera-ready copy (CRC) journal.

For detailed instructions regarding the elsevier article class, see https://www.elsevier.com/authors/policies-and-guidelines/latex-instructions

Bibliography styles

Here are two sample references: @Feynman1963118 [@Dirac1953888].

By default, natbib will be used with the authoryear style, set in classoption variable in YAML. You can sets extra options with natbiboptions variable in YAML header. Example

natbiboptions: longnamesfirst,angle,semicolon

There are various more specific bibliography styles available at https://support.stmdocs.in/wiki/index.php?title=Model-wise_bibliographic_style_files. To use one of these, add it in the header using, for example, biblio-style: model1-num-names.

Using CSL

If citation_package is set to default in elsevier_article(), then pandoc is used for citations instead of natbib. In this case, the csl option is used to format the references. Alternative csl files are available from https://www.zotero.org/styles?q=elsevier. These can be downloaded and stored locally, or the url can be used as in the example header.

Equations

Here is an equation: $$ f_{X}(x) = \left(\frac{\alpha}{\beta}\right) \left(\frac{x}{\beta}\right)^{\alpha-1} e^{-\left(\frac{x}{\beta}\right)^{\alpha}}; \alpha,\beta,x > 0 . $$

Here is another: \begin{align} a^2+b^2=c^2. \end{align}

Inline equations: $\sum_{i = 2}^\infty{\alpha_i^\beta}$

Figures and tables

Figure \ref{fig2} is generated using an R chunk.

```rA meaningless scatterplot.", echo = FALSE} plot(runif(25), runif(25))

# Tables coming from R

Tables can also be generated using R chunks, as shown in Table \ref{tab1} for example.

```r
knitr::kable(head(mtcars)[,1:4], 
    caption = "\\label{tab1}Caption centered above table"
)
