this is
    my custom
    enviro code

documentclass{article}
usepackage{color}

newcommand{bR}{ttfamilycolor{blue}$>$ }
newcommand{eR}{color{black}rmfamily}

begin{document}

Here is how I'd like to be able to type the latex code:

bR
xbar=mean(x)
summary(x)
hist(x)
eR

But here is what will give me the formatting that I want:

bR
xbar=mean(x)\
hspace*{0.32in} summary(x) \
hspace*{0.32in} hist(x) \
eR
