I have a function, say: f<-function(x) exp(x) and I would like to obtain the integration of the function while adding a few operations within the integration (I need point-by-point integration), say:
t<-seq(0,40, by=1) z<-array(0,length(t)) for (i in 1:40){ z[i] <- integrate ( f * (t [i+1] - t) , (i-1) , i ) In R, I can only have the function in 'integrate' i.e. z[i] <- integrate ( f , (i-1) , i ) but I want to add additional operations within the 'integrate' command, which I cannot just add to the function f. any input is appreciated.
