Rmarkdown numbered equation helper
View convert_align.R
#I write papers and reports using Rmarkdown, knitting to pdf.
#My co-authors use word, so I usually knit a version to docx for them to edit.
#This mostly works flawlessly, except when I use \begin{align} and \end{align} to delimit display equations.
#Using \begin{align} and \end{align} results in nicely centered and numbered equations in pdf, BUT
#the equations don't render at all when I try to make a docx.
#As a quick hack so I can make a passable docx to share with my co-authors, the following script replaces all instances
#of \begin{align} and \end{align} with "$$". The modified version of the original Rmarkdown file knits to docx just fine,
# albeit without equation numbers.

#function to substitute vowels with Maori macrons into text strings in R
#there's probably a fancier way to do this, but it works OK.
#just precede vowels requiring a macron with '@' and the function will substitute the appropriate vowel with macron.
#Handy for graph labelling etc.
x<-gsub("@a","\u0101", x) #macron a
x<-gsub("@e","\u0113", x) #macron e
x<-gsub("@i","\u012B", x) #macron i
x<-gsub("@o","\u014D", x) #macron o
