I am trying to convert a string to a vector, and I'm stuck!



Suppose you have a string of numbers (string) that you want to convert to a
vector (vec).  I am able to split the string turning it into a list by using
strsplit, but this makes a list, which I can't seem to access the way that
I'd like to (it becomes a character list of only one(?!?) element.)

string<-"1,1,2,3,5,8"

list<-strsplit(string,",")

list # Produces this ugly output with the [[1]] crap which doesn't let me
in!!!!!!!

It produces a list. To return an unlist-ed version, what else?

unlist(list)

[1] "1" "1" "2" "3" "5" "8"

And to make it a numeric vector ... also simple:

as.numeric(unlist(list))

[1] 1 1 2 3 5 8

string<-"1,1,2,3,5,8"
v <- scan(tc <- textConnection(string), sep=","); close(tc)

v

v <- scan(text=string, sep=",")
