Dear R people,
what functions generate respectively vectors with each element is
respectively zero and one.
sorry for my credulous questions and many thanks in advance.
If you want a *random* (i.i.d.) vector of zeroes and ones, then the
following sort of thing
will do it:
sample(0:1,42,TRUE) # TRUE is necessary for sampling with replacement.
sample(0:1,42,TRUE,prob=c(0.25,0.75)) # 1/4 zeroes and 3/4 ones on
average; the default is equal probabilities.
If you want some non-random structure, or if you want serial
dependence between the entries
you need to make your question more explicit.
*Do* read the posting guide!
cheers,
Rolf Turner
