[R] Placement of words in a word cloud as per its occurance.

[Jim Lemon]

Hi Shailaja,
If you just want a line of words, it's not too difficult if you have
the word frequencies:

# take a common sentence
sentence<-"The quick brown fox jumps over the lazy dog"
words<-unlist(strsplit(sentence," "))
# make up some word frequencies
wordfreq<-c(10,1,2,2,3,4,10,6,5)
library(plotrix)
# scale the frequencies into a convenient range
wordcex<-rescale(wordfreq,c(0.5,2))
x11(height=4)
# a simple function to display a vector of words in different sizes
wordline<-function(words,wordcex,space=0.005) {
 plotxy<-par("usr")
 x<-plotxy[1]
 y<-sum(plotxy[3:4])/2
 space<-diff(plotxy[1:2])*space
 for(i in 1:length(words)) {
  par(cex=wordcex[i])
  text(x,y,words[i],adj=0)
  x<-x+strwidth(words[i])+space
 }
}
# get an empty plot
plot(1:10,type="n",axes=FALSE,xlab="",ylab="")
# display the words
wordline(words,wordcex)

The function can be elaborated to fit the sentence into the available
space, break it into lines, all that sort of thing.
