My objective is to calculate the average of Theta across all pairs of two
demographics.
For 1 demographic this is straightforward:

"Housing")
means1 <- as.list(rep(0, length(Demo_names)))
for (i in 1:length(Demo_names)) {
Demo_tmp <- Demo_names[i]
means1[[i]] <- data_tmp[,list(mean(Theta)),by=Demo...
