looping through numbered variables
Hello,
This is a beginner question. I am trying to loop through numbered
variables with "apply" to calculate weighted means. My data is "data",
the variables are "var1" to "var100", the weight is "weight". The
command works using
sapply(paste('data$var', 1:100, sep=''), function(x)
weighted.mean(eval(parse(text=x)), data$weight))
