How to change digits of numbers in the export_summs() table

Question

I get the regression output table using export-summs() installed in the package called jtools and huxtable.

My code is: export_summs(model1, model2, scale = TRUE) and

          ────────────────────────────────────────────────────
                                Model 1          Model 2      
                           ───────────────────────────────────
            (Intercept)            0.28 **          0.00      
                                  (0.10)           (0.02)     
            educ                   0.09 ***                   
                                  (0.01)                      
            exper                  0.00 *                     
                                  (0.00)                      
            tenure                 0.02 ***                   
                                  (0.00)                      
            xtilde                                  0.09 ***  
                                                   (0.01)     
                           ───────────────────────────────────
            N                    526              526         
            R2                     0.32             0.23      
          ────────────────────────────────────────────────────
            *** p < 0.001; ** p < 0.01; * p < 0.05.

Is there any way to make all the digits 3 decimal numbers?

Assign the result of your export_summs() call to an object, and manipulate the format of specific rows and columns using huxtable::set_number_format(). Here is an example:

Some fake data and a couple of models

set.seed(123)
df = data.frame(x=rnorm(100), y = rnorm(100), g = sample(c(1:3),100, replace=T))
model1 = lm(y~x,data=df)
model2 = lm(y~x+factor(g), data=df)

Assigning the result of jtools::export_summs() to an object; this object is of class huxtable

model_table = jtools::export_summs(model1, model2, scale=T)

Now, use a fixed format (i.e. the "f" in "%.3f") for all the numbers in rows 2 through 9 and columns 2 through 3

huxtable::set_number_format(model_table,2:9,2:3,"%.3f")

Output:

You can pass a number_format string directly:

library(jtools)

model1 <- lm(drat ~ wt + hp, mtcars)
model2 <- lm(drat ~ hp, mtcars)

export_summs(model1, model2, scale = TRUE, number_format = "%.4g")
#> ----------------------------------------------------------------------------
#>                                   Model 1                  Model 2

haha.. much better than my round-about solution! – langtang Sep 03 '22 at 20:57 — langtang, Sep 03 '22 at 20:57
