I have tried to type variables in R code with LaTeX textgreek and knitr.

The problem is in source code formatting. There are no delimiting whitespaces in case of greek. enter image description here

You see?

The source Rnw:

\documentclass{article}

\usepackage[T2A]{fontenc}
\usepackage[utf8x]{inputenc}

\usepackage{textgreek}

\begin{document}

<<>>=
α <- 1
β <- 2
γ <- α + β 
α
β
γ
a <- 1
b <- 2
c <- 3
d <- a + b + c 
a
@

\end{document}

And that is generated tex:enter image description here

How can I fix that?

    I'm confused, what exactly is the problem? What is the encoding used for your source file? A [reproducible example](http://stackoverflow.com/questions/5963269/how-to-make-a-great-r-reproducible-example) would be helpful. Pictures of code aren't as nice because then we have to retype it all to see what's going on. – MrFlick Apr 04 '17 at 03:51
  • @MrFlick I've edited my question. The problem is in source code formatting. I've provided a link to my source at GitHub. Hope that will be good. – konstunn Apr 04 '17 at 04:07
  • It's better to create a minimal example required to reproduce the problem and include it in the question itself. External links to code that may disappear over time is discouraged. – MrFlick Apr 04 '17 at 04:08
  • @MrFlick, I've edited my question appropriately. – konstunn Apr 04 '17 at 04:19

    FYI, this bug in base R is said to be fixed in R 3.4.1, which was just released a few hours ago: https://stat.ethz.ch/pipermail/r-announce/2017/000616.html – Yihui Xie Jun 30 '17 at 13:52

I think this is a bug of base R, and I have filed a report to https://bugs.r-project.org/bugzilla3/show_bug.cgi?id=17254

Before it is fixed in base R, your only choice is to turn off syntax highlighting (or avoid multibyte characters in object names):

<<highlight=FALSE>>=
