How to change column names in stargazer when printing data frames?

latex, r, stargazer

Solution

A bit hacky, but the main idea here is to `gsub` out the relevant row in the `stargazer` output with our desired Latex code:

# Creating a data frame
df = data.frame(x = 1:5, y = 6:10)

out <- capture.output(
  stargazer(df, summary = F, 
    notes = "\\textsuperscript{1} This is a note that was supposed to refer to $Y$.")
)

# Changing names
vars = c("x" = "$X$", "y" = "$Y$\\\\textsuperscript{1}")
cat(sep = "\n",
  gsub(paste(names(vars), collapse = " & "), paste(vars, collapse = " & "), out)
)
# \begin{table}[!htbp] \centering 
#   \caption{} 
#   \label{} 
# \begin{tabular}{@{\extracolsep{5pt}} ccc} 
# \\[-1.8ex]\hline 
# \hline \\[-1.8ex] 
#  & $X$ & $Y$\textsuperscript{1} \\ 
# \hline \\[-1.8ex] 
# 1 & $1$ & $6$ \\ 
# 2 & $2$ & $7$ \\ 
# 3 & $3$ & $8$ \\ 
# 4 & $4$ & $9$ \\ 
# 5 & $5$ & $10$ \\ 
# \hline \\[-1.8ex] 
# \multicolumn{3}{l}{\textsuperscript{1} This is a note that was supposed to refer to $Y$.} \\ 
# \end{tabular} 
# \end{table}

When using argument `align = T`, try

vars = sprintf("\\\\multicolumn\\{1\\}\\{c\\}\\{%s\\}", 
  c("$X$", "$Y$\\\\textsuperscript{1}"))
names(vars) <- sprintf("\\\\multicolumn\\{1\\}\\{c\\}\\{%s\\}", names(df))
cat(sep = "\n",
  gsub(paste(names(vars), collapse = " & "), paste(vars, collapse = " & "), out)
)

Problem

I'm trying to output a data frame in latex using the stargazer package. I want the column names to include latex code, but stargazer does not allow latex code inside data frame names. I've also tried to use the column.labels argument, but this argument is only used for regression tables, not for outputting data frames. Here's the two approaches I've tried. Neither worked. First approach - trying to change the names of the variables in the data frame Code: ``` # Creating a data frame df = data.frame(x = 1:5, y = 6:10) # Changing names names(df) = c("$X$", "$Y$\\textsuperscript{1}") # Exporting stargazer(df, summary = F, notes = "\\textsuperscript{1} This is a note that was supposed to refer to $Y$.") ``` Output (clearly stargazer doesn't recognize the LaTeX code): ``` % Table created by stargazer v.5.2 by Marek Hlavac, Harvard University. E-mail: hlavac at fas.harvard.edu % Date and time: Sat, Oct 29, 2016 - 20:46:22 \begin{table}[!htbp] \centering \caption{} \label{} \begin{tabular}{@{\extracolsep{5pt}} ccc} \\[-1.8ex]\hline \hline \\[-1.8ex] & \$X\$ & \$Y\$\textbackslash textsuperscript\{1\} \\ \hline \\[-1.8ex] 1 & $1$ & $6$ \\ 2 & $2$ & $7$ \\ 3 & $3$ & $8$ \\ 4 & $4$ & $9$ \\ 5 & $5$ & $10$ \\ \hline \\[-1.8ex] \end{tabular} \end{table} ``` Second approach – trying to use the column.labels argument Code: ``` # Creating a data frame df = data.frame(x = 1:5, y = 6:10) # Exporting stargazer(df, summary = F, column.labels = c("$X$", "$Y$\\textsuperscript{1}"), notes = "\\textsuperscript{1} This is a note that was supposed to refer to $Y$.") ``` Output (stargazer simply ignores the argument): ``` % Table created by stargazer v.5.2 by Marek Hlavac, Harvard University.
