Nothing spectacular, but yet interesting little useless R function for playing with strings and chars.
Converting Sentence case text to mixture of all and small caps resulting in sentence in mixed case.
"This is useless R Function that seems to exists."
"This is UsEleSS r FuNcTion THaT SeEms To ExIsTS."
And many other mixture of cases. So by calling this function, the results will give you the mixed cases string.
Talk about useless functions
Code is also available at Github. Feel free to improve it with even more wackiness
