weighted lm() Messages sorted by: [ date ] [ thread ] [ subject ] [ author ] No one replied to this, so I'll try again, with a simple example. I calculate a set of log odds ratios, and turn them into a data frame as follows: > library(vcdExtra) > (lor.CM <- loddsratio(CoalMiners)) log odds ratios for Wheeze and Breathlessness by Age 25-29 30-34 35-39 40-44 45-49 50-54 55-59 60-64 3.695261 3.398339 3.140658 3.014687 2.782049 2.926395 2.440571 2.637954 > > (lor.CM.df <- as.data.frame(lor.CM)) Wheeze Breathlessness Age LOR ASE 1 W:NoW B:NoB 25-29 3.695261 0.16471778 2 W:NoW B:NoB 30-34 3.398339 0.07733658 3 W:NoW B:NoB 35-39 3.140658 0.03341311 4 W:NoW B:NoB 40-44 3.014687 0.02866111 5 W:NoW B:NoB 45-49 2.782049 0.01875164 6 W:NoW B:NoB 50-54 2.926395 0.01585918 7 W:NoW B:NoB 55-59 2.440571 0.01452057 8 W:NoW B:NoB 60-64 2.637954 0.02159903 Now I want to fit a linear model by WLS, LOR ~ Age, which can do directly as > lm(LOR ~ as.numeric(Age), weights=1/ASE, data=lor.CM.df) Call: lm(formula = LOR ~ as.numeric(Age), data = lor.CM.df, weights = 1/ASE) Coefficients: (Intercept) as.numeric(Age) 3.5850 -0.1376 But, I want to do the fitting in my own function, the simplest version is my.lm <- function(formula, data, subset, weights) { lm(formula, data, subset, weights) } But there is obviously some magic about formula objects and evaluation environments, because I don't understand why this doesn't work. > my.lm(LOR ~ as.numeric(Age), weights=1/ASE, data=lor.CM.df) Error in model.frame.default(formula = formula, data = data, subset = subset, : invalid type (closure) for variable '(weights)' > A second question: Age is a factor, and as.numeric(Age) gives me 1:8.
