The weighted.mean() function replaces NA values with 0.0 when the user
specifies na.rm=TRUE:
x <- c(101, 102, NA)
mean(x, na.rm=TRUE) # 101.5, correct
weighted.mean(x, na.rm=TRUE)# 67.7, wrong
weighted.mean(x, w=c(1,1,1), na.rm=TRUE)# 67
I observed the following:
match.arg("white", colors())
yields 'white', but
match.arg("whit", colors())
yields:
`Error in match.arg("whit", colors()) :
'arg' should be one of "white", "aliceblue", '...
this message actually comes from `pmatch'. using a suitable subset of
`colors()' works

I believe the answer is that you are missing something: partial matching.
The 651'st elt of colors() is "whitesmoke", so it is ambiguous whether
"whit" matches "white" or "whitesmoke". When you leave out the 651'st
elt, "whit" happily matches "white".

If that does not help, using options(useFancyQuotes = TRUE) in the
