creating a vector from a file
So you need to read a file into R in that format?
Try changing the values in ?read.table. Using the example, I was able
to get the data using:
read.table("clipboard", sep = "=", header = F, colClasses =
c("character", "numeric"))

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 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. PH http://www.rforge.net/doc/packages/snippets/cloud.html ? ? ? [[alternative HTML version deleted]]
