[R] creating a vector from a file

Hello all,
I am new to R and my question should be trivial. I need to create a word
cloud from a txt file containing the words and their occurrence number. For
that purposes I am using the snippets package [1].
As it can be seen at the bottom of the link, first I have to create a vector
(is that right that words is a vector?) like bellow.

> words <- c(apple=10, pie=14, orange=5, fruit=4)

My problem is to do the same thing but create the vector from a file which
would contain words and their occurence number. I would be very happy if you
could give me some hints.

Moreover, to understand the format of the file to be inserted I write the
vector words to a file.

> write(words, file="words.txt")

However, the file words.txt contains only the values but not the
names(apple, pie etc.).

$ cat words.txt
10 14 5 4

It seems that I have to understand more about the data types in R.

Thanks.
PH
