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.
How is the file formatted? Can you provide a small example?
The file format is
"video tape"=8
"object recognition"=45
"object detection"=23
"vhs tape"=2
Something like this may work:
words <- read.table(file="name.txt", sep="=", header=FALSE)
wvec <- words$V1
names(wvec) <- rownames(words)
Need to change the header argument and the col-name argument to "$" if
you have a header line.

But I can change it if needed with bash scripting.
Regards
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.
