writexl::write_xlsx() dynamic sheet name

I am trying to write an excel file and dynamically update its sheet name using writexl::write_xlsx().

In the code below, my intention is to name the sheet as "my_sheet_has_32_rows" using the vector my_sheet_name, but the code names the sheet as "my_sheet_name".

#> Warning: package 'writexl' was built under R version 4.1.2
# Data
df <- mtcars
n_rows <- (nrow(df))

my_sheet_name <- paste0("my_sheet_has_", n_rows, "_rows")
#> [1] "my_sheet_has_32_rows"

writexl::write_xlsx(list(my_sheet_name = df),

You can use setNames()

write_xlsx(setNames(list(df), my_sheet_name), "data/my_file_name.xlsx")
