Weighting data when running regressions
...ression on a subset of my data file where WEIGHT is the name of my weighting variable (numeric), e.g.: library(foreign) data1=read.spss("File.sav", use.value.labels = FALSE, to.data.frame = TRUE) summary(data1) ' shows me all the variables OK attach(data1) linmod=lm(Y~X1+X2+X3+X4W, subset=(X5==1 & X6==7), weights==WEIGHT) and I get the following Error message: Error in weights == WEIGHT : comparison (1) is possible only for atomic and list types It works perfectly if I don't use the ", weights==WEIGHT" bit Could you please let me know...
