Re: [R] Percent of a given subset

There are almost surely a brazillion ways. Here's one: Call your data frame "X". Do: XT <- xtabs(AvailableMW~Bands+FuelTypeNum,data=X) PXT <- 100*XT/apply(XT,1,sum) print(round(PXT,2)) This gives percent of fuel type 1 in band PB0 as 0.54 53.87 3.93 41.65 to two decimal places

[R] Percent of a given subset

How would I find the Percent of FuelTypeNum within the Band given AvailableMW? example: type 1 is 1% of PB0 type 2 is 54% of PB0 type 4 is 4% of PB0 type 5 is 42% of PB0 Note: the Bands and fuel types are not always constant. Data: FuelTypeNum Bands AvailableMW Avai
