I have a vector of land cover class data from a GIS: > landcov[1:10,2] #the first ten examples of a large (100k+) object 1 2 3 4 5 6 7 8 9 10 12 12 01 12 01 15 15 15 15 15 etc. I also have a lookup table for the class data that gives the cover type as a string: > cnd.names #the look up table, i.e., landcov[3,2] == 1 == "Montane Meadow" CndVal

I have 4 years of data and for each year, I have initialize the value so now for fitting the model, I want to remove the initial value and get the model based on remaining data set.

For each person in a household I want to create two new variables OrigTAZ and DestTAZ. It should take the value in TripendTAZ and put that in DestTAZ. For OrigTAZ it should put value of TripendTAZ from the previous row. For the first trip of every

Hi, I am trying to work with the ape package, and there is one thing I am struggling with.

I would like to create a subtotal table with custom bands. seq1 = seq(0, 100, by = 5) seq2 = seq(100, 1000, by = 100) Bands = c(seq1, seq2) #Prices Prices = sample(1:1000, 200, replace=F) #corresponding size for the given price above. size = sample(1:1000, 200, replace=F) How would I find the subtotal of the size based on a given price falls within a band? -- View this message in
