How to change the weighted N count in the column header ("N = 6,194") of the table above to unweighted n count?
The table was created with a default dataset using the following code:
library(gtsummary)
library(survey)
data(api)
svydesign(id = ~dnum, weights = ~pw, data = apiclus1, fpc = ~fpc) |>
tbl_svysummary(include = c(api00, stype),
statistic = list(all_continuous() ~ "{mean} ({sd})",
all_categorical() ~ "{n_unweighted} ({p}%)"))
Thank you for your help!
To get the header with unweighted statistics. You'll first need to install the development version of the package. I've included code below to install and build the table. Hope it helps!

Note: In your example, for the stype
variable we're mixing unweighted counts (n_unweighted
) and weighted proportions (p
).
