Create counter variable for subsets without a loop
Hi all,
I am looking to create a rank variable based on a continuous variable
for subsets of the data. For example, for an R integrated data set
about US states this is how a loop could create what I want:
### Example with loop
data <- cbind(state.region,as.data.frame(state.x77))[,1:2] #
choosing a subset of the data
data <- data[order(data$state.region, 1/data$Population),] #
