With the CRAN version of {styler} (1.6.2), I get:
styler::style_text('
`Correct Answer` =
c(
39,
"1756",
13,
"156",
"910,000",
"4,160",
"2,159",
"5,941",
"524.0",
"18.7"
)')
#>
#> `Correct Answer` <-
#> c(
#> 39,
#> "1756",
#> 13,
#> "156",
#> "910,000",
#> "4,160",
#> "2,159",
#> "5,941",
#> "524.0",
#> "18.7"
#> )

Alternatively, the Addin or the other style_*() functions give the same result, so maybe you just need to update the {styler} package.
