Using R to extract specific column in Azure ML -


i have created forecasting causal model in azure ml studio determines organization's hiring needs every month 2015. since causal model, individually forecast parameters 2015 , supply them model.

one such factor previous 9 months hire value. means if forecasting hire value jan-2015, previous 9 month hire values considered (dec - april 2014).

the following parameter set:

year    month   factor    factor b    factor c    factor d    prev. month-1   prev. month-2   prev. month-3   prev. month-4   prev. month-5   prev. month-6   prev. month-7   prev. month-8   prev. month-9

sample input:

year    month   factor    factor b    factor c    factor d    prev. month-1   prev. month-2   prev. month-3   prev. month-4   prev. month-5   prev. month-6   prev. month-7   prev. month-8   prev. month-9 2015    1       2           4           6           8           10              11              12              13              14              15              16              17              18

once run model, forecasted hire (score labels) output:

year    month   factor    factor b    factor c    factor d    prev. month-1   prev. month-2   prev. month-3   prev. month-4   prev. month-5   prev. month-6   prev. month-7   prev. month-8   prev. month-9   score labels 2015    1       2           4           6           8           10              11              12              13              14              15              16              17              18              19

for forecasting february-2015, forecasted value january becomes prev. month-1 value. 

year    month   factor    factor b    factor c    factor d    prev. month-1   prev. month-2   prev. month-3   prev. month-4   prev. month-5   prev. month-6   prev. month-7   prev. month-8   prev. month-9 2015    1       2           4           6           8           10              11              12              13              14              15              16              17              18 2015    2       3           5           7           9           19              10              11              12              13              14              15              16              17

this becomes bit tedious have repeat 12 times - 1 each month. can suggest how solve using r script? here have written far:

dataset <- maml.mapinputport(1)   previous <- 9 orig_names <- names(dataset) n_rows <- dim(dataset)[1]  base <- 9 (i in 1:previous) {   dataset[(i+1):n_rows,base+i] <- dataset[1:(n_rows-i),base]   dataset[1:i,base+i] <- dataset[1:i,base+i-1] }  <- -1:-previous new_names <- paste("prev. month",a) names(dataset) <- c(orig_names,new_names)  maml.mapoutputport("dataset")

thanks.

update 1

i have managed execute model in loop in azure. each iteration, need provide input parameters (like february).

can me on how obtain forecast under "score labels" , append parameter under "prev. month-1" input next month in r?
