R - How can I calculate a matrix with a function? -


i have problem following code in r. want myfun() function write data my.res matrix. can print statement my.vec[i]/my.vec[i-j] easily.

my.vec <-c(1:10) my.res <-matrix( ,10,2)  myfun <-function(j=2){    for(i in (j+1):10){      my.res[i,1] <-my.vec[i]/my.vec[i-j]      print(my.vec[i]/my.vec[i-j])    } }

you have print in wrong location, changed input j=2 j can assigned. mentioned - don't need loop - seems trying learn how work loops?

myfun <- function(j){   for(i in (j + 1):10){     my.res[i,1] <- my.vec[i]/my.vec[i-j]   }   print(my.res) }  myfun(2)

consider following python command-line program. doesn't work because incomplete, think illustrates problem: #!/usr/bin/python3 import multiprocessing pool = multiprocessing.pool() task in expensive_iterator_with_user_interaction(): pool.call_async(expensive_computation, (task,)) pool.close() print("dear user, may press ctrl-z , bg script.") pool.join() thus, problem scripts needs user input while it's launching expensive parallel processes. there moment when user interaction not needed anymore. then, ask user background process shell actions. however, can achieved program itself? (side note: core of problem entanglement of user input firing “expensive computations”. therefore, cannot separate both in 2 scripts, , letting 1 spawning other daemon.) the command screen may you. use screen -l create new session , run application. after inputting data, can press " ctrl-a " , press " d " on keyboard detach session. now
