Rmarkdown – How to Add LaTeX to Rmarkdown to Be Within Text Rather Than Centered When Knitted

equationsrmarkdown

I am writing text in RMarkdown that includes equations that I type in LaTeX. However, rather than including them on the same line within the text, it breaks the line and centres the equation. How can I write LaTeX equations on the same line within text in RMarkdown?

Here is an example of how I wrote my text in Rmd:

The slope of the least squares line is 1.4083\[\approx\]1.4. It is meaningful over the range \[x \in [113.082, 1262.274]\] where the regression line exists along the x-axis.

And here's an image of the result after knitting the Rmd file.

You are using the "display math mode". For the "inline math mode" use $ ... $ or $ ... $ .

The slope of the least squares line is
\(1.4083\approx1.4\).
It is meaningful over the range
\(x \in [113.082, 1262.274]\)
where the regression line exists along the x-axis.

The problem comes down to a change in cleveref, which now seems to have a load order requirement with amsmath which was not previously the case. With the minimal example

\documentclass{article}
\usepackage{cleveref}
\usepackage{amsmath}

\begin{document} 

\begin{equation}
\label{eq:structprop}
a
\end{equation} 

\cref{eq:structprop}

\end{document}

The issue is visible with the current cleveref release, but did not occur previously.

Sure, this is not absolutely perfect, but it is very close without going into too much finicky detail about the spacing (click to enlarge):

\documentclass[leqno]{article}
\usepackage{amsmath}% http://ctan.org/pkg/amsmath
\begin{document}
Let~$f$ represent the resulting number of such two-step cycles that operate per second (expressed in Hz.)

\noindent\begin{minipage}{0.5\linewidth}
\begin{equation}
  f = \frac{1}{t_{\text{on}} + t_{\text{off}}} \label{eq:f}
\end{equation}
\end{minipage}%
\begin{minipage}{0.5\linewidth}
\begin{equation}
  \frac{1}{f} = t_{\text{on}} + t_{\text{off}} \label{eq:invf}
\end{equation}
\end{minipage}\par\vspace{\belowdisplayskip}

The total time required per cycle is the inverse of frequency of those cycles.

\begin{equation}
  f = \frac{1}{t_{\text{on}} + t_{\text{off}}} \label{eq:ff}
\end{equation}
The total time required per cycle is the inverse of frequency of those cycles.

\end{document}

The generic view on the "two-column look" is

\noindent\begin{minipage}{0.5\linewidth}
...
\end{minipage}%
\begin{minipage}{0.5\linewidth}

\end{minipage}

Some highlights:

\noindent avoids a regular \parindent (which is a common source of "overfull \hbox warnings" in this case);
Each minipage is exactly half the width of the text block (0.5\linewidth);
The use of % at the end of the first minipage is crucial to avoid an extra inter-word space between the minipages (you only have \linewidth to work with, not \linewidth +\space). See What is the use of percent signs (%) at the end of lines?

The final \vspace is to accommodate for an imperfect skip after a minipage. In fact, this is a known problem that using minipages causes some skip of the baseline to be not ideal. More on this conundrum is available from How to keep a constant \baselineskip when using minipages (or \parboxes)?
