Basic mean calculation

Question

V1 is the frequency of V2 Is there a easy way to calulate the V2 mean? Or do i have to transform my table?

my data is structured like this:

Could you please show what has already failed? `mean(df$V2)`? — NelsonGon, Oct 02 '19 at 14:03

You can use sum like

sum(x$V1*x$V2) / sum(x$V1)
