hi, i'd like to calculate a temperatursum, adding the value of each element. let's say the data looks like this: x<-c(1,2,3,4,5) what i want to do, is ploting not the sum in the end but all the subresults, too, so my vector holds: x[i] [1] 1,3,6,10,15 here is what i tried, which seems to be right to me, bu doesn't work out: x<-c(1,2,3,4,5) i<-1 j<-1 z[j]<-x[i]+x[i+1] p<-z[j] j<-2:4 i<-3:5 z[j]<-z[j-1]+x[i] plot (c(p,z[j]) what i get is: [1] 6.0 12.0 9.2 18.0 any s...
