I am using the 'rticle' package in R which allows building R markdown documents based on pre-specified templates for the journal submission. The template is in .tex format and as shown in the figure, I am using PLOS template. However, I am not able to remove the space from the superscript. red circle

The code responsible for this is the following (I believe)

    % Template for PLoS
% Version 3.4 January 2017

% amsmath and amssymb packages, useful for mathematical formulas and symbols

% Use adjustwidth environment to exceed column width (see example table in text)

% Use Unicode characters when possible

% textcomp package and marvosym package for additional characters

% cite package, to clean up citations in the main text. Do not remove.
% \usepackage{cite}

% Use nameref to cite supporting information files (see Supporting Information section for more info)

% line numbers

% ligatures disabled
\DisableLigatures[f]{encoding = *, family = * }

% color can be used to apply background shading to table cells only

% array package and thick rules for tables

% create "+" rule type for thick vertical lines
\newcolumntype{+}{!{\vrule width 2pt}}

% create \thickcline for thick horizontal lines of variable length
  \noalign{\global\savedwidth\arrayrulewidth\global\arrayrulewidth 2pt}%

% \thickhline command for thick horizontal lines that span the table
\newcommand\thickhline{\noalign{\global\savedwidth\arrayrulewidth\global\arrayrulewidth 2pt}%

% Remove comment for double spacing

% Text layout
\textwidth 5.25in
\textheight 8.75in

% Bold the 'Figure #' in the caption and separate it from the title/caption with a period
% Captions will be left justified

% Use the PLoS provided BiBTeX style
% \bibliographystyle{plos2015}

% Remove brackets from numbering in List of References

% Leave date blank

% Header and Footer with logo
\renewcommand{\footrule}{\hrule height 2pt \vspace{2mm}}
\lfoot{\sf PLOS}

%% Include all macros below
\newcommand{\lorem}{{\bf LOREM}}
\newcommand{\ipsum}{{\bf IPSUM}}









% Title must be 250 characters or less.
\textbf\newline{$title$} % Please use "sentence case" for title and headings (capitalize only the first word in a title (or heading), the first word in a subtitle (or subheading), and any proper nouns).
$author.name$\textsuperscript{$for(author.affiliation)$\getAff{$author.affiliation$}$sep$, $endfor$}$if(author.corresponding)$\textsuperscript{*}$endif$$sep$,
* Corresponding author: $author.email$\\
% Please keep the abstract below 300 words

% Please keep the Author Summary between 150 and 200 words
% Use first person. PLOS ONE authors please skip this step.
% Author Summary not valid for PLOS ONE submissions.
\section*{Author summary}


% Use "Eq" instead of "Equation" for equation citations.




Thank you in advance.

    Welcome to TeX.SX! Please make your code compilable (if possible), or at least complete it with \documentclass{...}, the required \usepackage's, \begin{document}, and \end{document}. That may seem tedious to you, but think of the extra work it represents for TeX.SX users willing to give you a hand. Help them help you: remove that one hurdle between you and a solution to your problem. – Stefan Pinnow Jan 22 '19 at 5:31

Since there is no MWE to try out, I can only guess, that you are introducing unwanted whitespace in the definition of \getAff and \getIndex. You can get rid of it by adding a % at the line endings:

\newcommand{\getAff}[1]{% <-- HERE
\getIndex{#1}{$for(address)$$address.code$$sep$,$endfor$}% <-- HERE

\newcommand{\getIndex}[2]{% <-- HERE
  \ForEach{,}{\IfEq{#1}{\thislevelitem}{\number\thislevelcount\ExitForEach}{}}{#2}% <-- HERE

To understand what is going on, have a look here: What is the use of percent signs (%) at the end of lines?

  • Thank you for the comment. It works to remove the space in the left by placing % in \getAff}[1]{% and \getIndex}[2]{%, but I am not able to get rid of space in right. Please check the new figure. – JohnS Jan 22 '19 at 14:16
