r - Grouping data by ID or seed -


i have 100 patient's data (1 total file rbind) 2 columns (time,var1). need group data (100 groups) in order able plot 100 patient's data.

i added column patientid @ end whole data, should grouped in order generate 100 plots each patient. since need data dont want split total data.

i tried , didn't work:

data1$id <- 1  # third column has id total <- rbind(data1,data2,....) total <- grouped.data(xdata = xdata, ydatalog = ydatalog, seed = total$id) plot(total)

as example, data r works properly:

str(loblolly) classes ‘nfngroupeddata’, ‘nfgroupeddata’, ‘groupeddata’ , 'data.frame':      84 obs. of  3 variables:

plot(loblolly) # 1 plot each patient since data grouped

solution: total.new <- # create new copy object groupeddata( ydatalog ~ xdata | id, data = as.data.frame( total ),.
