Internally, printing/formatting of yearmon objects uses the format method 
for Date objects, see ?format.Date. The default is "%b %Y" where %b is the 
abbreviated month name in the current locale. %B gives you the full month 
name, both for Date directly and for yearmon:

R> format(Sys.Date(), "%B %Y")
[1] "April 2019"
R> format(as.yearmon(Sys.Date()), "%B %Y")
[1] "April 2019"
