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.

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

    % Template for PLoS

Thank you in advance.

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}{numberthislevelcountExitForEach}{}}{#2}% <-- HERE

}

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