cycling k times a realization of a random walk.....problems..
...realization on the same plot.
IN OTHER WORDS I'D LIKE TO IMPOSE A LOOPING CYCLE TO THE COMMAND NOT THE ARGUMENT OF THE COMMAND.
for some of these questions i have already a partial answer: my main problem here is automatizing the process for 100 times.
my random walk generating function is:
rwalk <- function(n,p, x0=0)
? ? ? ???{
? ? ? ? ? x <- rbinom(n,1,p)
? ? ? ? ? x[which(x==0)] <- -1
? ? ? ? ? y<-c(x0,x)
? ? ? ? ? y <- cumsum(y)
? ? ? ? ???}
THIS IS THE CODE THAT I'D LIKE TO REITERATE
a<- rwalk(n,p,x0=0) #whish to generate 100 of those
#and for each calculate t...
