 extract_numeric(playerStats)

       4             NA

------------------------------------------------------------------------------------------------
 playerStats[c(22,24)]
[1] "Max Link Length x Days 276 km-days"      "Largest Field MUs x
Days 83,226 MU-days"
--------------------------------------------------------------------------------------------

I do not understand why these two vectors return NA when the function
extract_numeric() works well for others,

Any wrong settings in my env?

Thank you for hints.
