density plot for weighted data
I'm trying to create a density plot using census data, where the
weights don't sum to 1.
>plot(density(oh$FINCP,weights=oh$PWGTP))
Warning message:
In density.default(oh$FINCP, weights = oh$PWGTP) :
sum(weights) != 1 -- will not get true density
How would I go about doing this?
Thanks!

Decimals in R/SQL
...or RSQLite I lose the decimals in my matrix.
The only way I can get decimals is by multiplying by 1.00000, etc. I
have tried manipulating the options, but it is only effective once I
multiply by 1.0000.
I appreciate any suggestions!
Thanks!
Example:
z <- sqldf ("select ST,
SUM(AGEP*PWGTP)*1.000000000/SUM(PWGTP)*1.00000000000000 as wgtage from
ss09 group by ST")
z shouldn't be whole numbers.
