Is the ~ character the equivalent of ! character

whats the R translation of this ?

sub_df = df [
(df["test_result"].isin(test_vals))
& (~df["value"].isin(na_vals))
]

test_vals = [
"positive",
"negative"
]

dup_na_vals = [
"na",
"",
"unknown"
]

! is the "not" operator.

help("!") will bring up the documentation
