stargazer left align LaTeX table columns

Question

stargazer automatically centres values within tables. How can I left align the columns?

Put this code in an .Rnw file and use knitr to convert to .tex:

<<load, echo=FALSE, warning=FALSE, message=FALSE>>=
opts_chunk$set(eval=TRUE, echo=FALSE, warning=FALSE, message=FALSE, dpi=300)
@


\documentclass[a4paper,11pt]{article}
\usepackage{lipsum} % Required to insert dummy text

\begin{document}
\title{}
\author{}
\date{\today}
\maketitle

\section{Header}

<<iris, results = "asis">>=
library(stargazer)
stargazer(iris[1:10,4:5], summary  = FALSE)

Quick and dirty way would be to use regular expression to find the ccc string in \begin{tabular} and change it to lcc. — Roman Luštrik
Post processing looks like the only way. The built-in styles don't have alignment capabilities either. — Thell
For such straightforward table, why do you insist on using stargazer? You might have much more options to fine-tune the LaTeX table with e.g. xtable. — daroczig

As has been pointed out in the comments, you could either post-process the output of stargazer, or use xtable. I'll demonstrate both approaches.

post-processing: Replace your code chuck with the following two code chunks

<<echo=FALSE, results=hide>>=
library(stargazer)
tab <- stargazer(iris[1:10,4:5], summary  = FALSE) 
@

<<results=tex, echo=FALSE>>=
collapse <- function(st) paste(st, collapse="")
st <- gsub(collapse(rep("c", 3)), collapse(rep("l",3)), tab)
cat(st[4:24])
@

xtable: After installing the xtable package, you could use this as your code chuck

<<iris, results="asis", echo=FALSE>>=
library(xtable)
print(xtable(iris[1:10,4:5], align="lll", caption=""))
@

I think the xtable approach is probably easier though
