A _Date_ is comprised of three values for _year_, _month_ and _day_.
What you supplied does not match that requirement.
Hence the failure you see, and one way to overcome this (by specifying an
arbitrary day, here the first):
> as.Date("202012", "%Y%m")
[1] NA
> as,Date(paste0("202012", "01"), "%Y%m%d")
[1] "2020-12-01"

even when we correct the inadequate '%y' parser others have pointed out.
And the incorrect comma in as,Date...
as,Date(paste0("202012", "01"), "%Y%m%d")
#> Error: unexpected ',' in "as,"
as.Date(paste0("202012", "01"), "%Y%m%d")
#> [1] "2020-12-01"
Hope this helps,
