I was wondering if someone came with a solution to show up the reference categories of categorical variables using stargazer
?
library(stargazer
If you are willing to accept my revised strategy, then extract the names of the xlevels
-lidt-item in the lm1-object, and their associated first levels and substitute the pasted character values for the "(Intercept) value:
baselines = sapply( lm1$xlevels, "[[", 1)
names(lm1$coefficients)[1] = paste0( names(baselines), " = ", baselines,
collapse="; ")
I now get:
stargazer(lm1, single.row = TRUE, omit.table.layout = "sn")

I don't seem to have a properly configured Latex toolchain anymore, probably due to the "enhanced security features" Apple introduced in the last OSX "upgrade".
You can achieve the output you want by providing covariate.labels
to stargazer
:
library(magrittr)
library(stringr)
library(stargazer)
covlabels <-
names(lm1$coefficients)[-1] %>%
if_else(str_sub(., 1, 4) == "gear" | str_sub(., 1, 4) == "carb", paste("\\-\\hspace{0.3cm}", .), .) %>%
if_else(str_sub(., 18, 24) == "gear4", paste("gear (ref=3) \\\\", .), .) %>%
if_else(str_sub(., 18, 24) == "carb2", paste("carb (ref=1) \\\\", .), .)
stargazer(lm1, single.row = TRUE, omit.table.layout = "sn", covariate.labels=covlabels)
yields
