Display p-values under 0.1 in r stargazer

I have regression coefficients at p-value 0.06. The output table of stargazer does not display the dot (.) signalling p-values under 0.1. How do I make stargazer to signal p-values below 0.1 in the output table?

*It would be hard to find or create a reproducible example with p-values above 0.05 and below 0.1. If needed, I'll try and find something. But hopefully this is a softball question with a quick solution.

You can do this with the star.cutoffs and star.char arguments. Some fake data below to demonstrate:

library(stargazer)

# Generate some fake data
set.seed(10)
x <- rnorm(10)
x1 <- rnorm(10)
e <- rnorm(10)
y <- 10 + x + 2*x1 + e

# Estimate a model
m1 <- lm(y~x + x1)

# We can see that we have three different levels of sig at typical cutoffs
summary(m1)
#> 
#> Call:
#> lm(formula = y ~ x + x1)
#> 
#> Residuals:
#>      Min       1Q   Median       3Q      Max 
#> -1.12552 -0.20126 -0.06919  0.60370  0.76845

#> F-statistic: 15.59 on 2 and 7 DF,  p-value: 0.002639

# We will make the 10% level a plus sign, and stars for .05, .01 and .001
stargazer(m1, type = "text",
          star.char = c("+", "*", "**", "***"),
          star.cutoffs = c(.1, .05, .01, .001))
