As part of a package I'm creating in R I have a function that calculates a set of values for peptide sequences. The scientific agreement is for these values to be named yº3, bº6, xº13, etc. and so I would like to followed this. In the R GUI (on a Mac at least) 'º' is an acceptable character, that can be used in character strings etc. meaning that I can successfully create a function outputting a data frame with a column containing the desired names.

The problems come when I try to build the package containing the function. The terminal doesn't understand this character and substitutes it for \xbc when running the same function from the build package...

Is there anyway of circumventing this shortcoming of the package builder/terminal

I ran into this solution for a question I asked for a different application here. Unicode is the way to go. As Andrie points out you can use unicode

  • U+00BA For the masculine ordinal indicator
  • U+00B0 For the degree symbol

Include them in the form \uxxxx , i.e. small u and without the +.
