Export regression summaries to tables

This function allows users to use the features of summ() (e.g., standardization, robust standard errors) in the context of shareable HTML, LaTeX, and Microsoft Word tables. It relies heavily on huxtable::huxreg() to do the table formatting. This is particularly useful for putting the results of multiple models into a single table.

export_summs(..., error_format = "({std.error})",
  error_pos = c("below", "right", "same"), ci_level = 0.95,
  statistics = NULL, model.names = NULL, coefs = NULL,
  to.file = NULL, file.name = NULL)

At minimum, a regression object(s). See details for more arguments.


Which of standard error, confidence intervals, test statistics, or p values should be used to express uncertainty of estimates for regression coefficients? See details for more info. Default: "(std.error)"


Where should the error statistic defined in error_style be placed relative to the coefficient estimate? Default: "below"


If reporting confidence intervals, what should the confidence level be? By default, it is .95 if confidence intervals are requested in error_format.


Which model summary statistics should be included? See huxreg for more on usage. The default for this function depends on the model type. See details for more on the defaults by model type.


If you want to give your model(s) names at the top of each column, provide them here as a character vector. Otherwise, they will just be labeled by number. Default: NULL


If you want to include only a subset of the coefficients in the table, specify them here in a character vector. If you want the table to show different names for the coefficients, give a named vector where the names are the preferred coefficient names. See details for more.


Export the table to a Microsoft Word, PDF, or HTML document? This functionality relies on huxtable's quick_ functions (huxtable::quick_docx(), huxtable::quick_pdf(), huxtable::quick_html(), huxtable::quick_xlsx()). Acceptable arguments are "Word" or "docx" (equivalent), "pdf", "html", or "xlsx". All are case insensitive. Default is NULL, meaning the table is not saved.


File name with (optionally) file path to save the file. Ignored if to.file is FALSE. Default: NULL


There are many optional parameters not documented above. Any argument that you would want to pass to summ(), for instance, will be used. Of particular interest may be the robust and scale arguments. Note that some summ arguments may not have any bearing on the table output.

The default model summary statistics reporting follows this logic:

  • summ.lm = c(N = "nobs", R2 = "r.squared"),

  • summ.glm = c(N = "nobs", AIC = "AIC", BIC = "BIC", `Pseudo R2` = "pseudo.r.squared"),

  • summ.svyglm = c(N = "nobs", R2 = "r.squared"),

  • summ.merMod = c(N = "nobs", AIC = "AIC", BIC = "BIC", `R2 (fixed)` = "r.squared.fixed", `R2 (total)` = "r.squared")

  • summ.rq = c(N = "nobs", tau = "tau", R1 = "r.1", AIC = "AIC", BIC = "BIC")

Be sure to look at the summ() documentation for more on the calculation of these and other statistics, especially for mixed models.

If you set statistics = "all", then the statistics argument passed to huxreg will be NULL, which reports whichever model statistics are available via glance. If you want no model summary statistics, set the argument to character(0).

You have a few options for the error_format argument. You can include anything returned by broom::tidy() (see also tidy.summ()). For the most part, you will be interested in std.error (standard error), statistic (test statistic, e.g. t-value or z-value), p.value, or conf.high and conf.low, which correspond to the upper and lower bounds of the confidence interval for the estimate. Note that the default ci_level argument is .95, but you can alter that as desired.

To format the error statistics, simply put the statistics desired in curly braces wherever you want them in a character string. For example, if you want the standard error in parentheses, the argument would be "({std.error})", which is the default. Some other ideas:

  • "({statistic})", which gives you the test statistic in parentheses.

  • "({statistic}, p = {p.value})", which gives the test statistic followed by a "p =" p value all in parentheses. Note that you'll have to pay special attention to rounding if you do this to keep cells sufficiently narrow.

  • "[{conf.low}, {conf.high}]", which gives the confidence interval in the standard bracket notation. You could also explicitly write the confidence level, e.g., "CI [{conf.low}, {conf.high}]".

For coefs, the argument is slightly different than what is default in huxreg. If you provide a named vector of coefficients, then the table will refer to the selected coefficients by the names of the vector rather than the coefficient names. For instance, if I want to include only the coefficients for the hp and mpg but have the table refer to them as "Horsepower" and "Miles/gallon", I'd provide the argument like this: c("Horsepower" = "hp", "Miles/gallon" = "mpg")

You can also pass any argument accepted by the huxtable::huxreg() function. A few that are likely to be oft-used are documented above, but visit huxreg's documentation for more info.
