Below is an example of the code to generate the cloud :
comparison.cloud(tdm, random.order=FALSE,
colors = c("tomato", "wheat", "lightblue","lightgreen"))
The words are easily colored with the above command but the labels are still gray.
I found a solution:
I've found that to do this you need to go to source code . Just go to R-Forge or check through the console itself.
Then change a line by adding the color parameter col=colors[i] as seen below:
rect(x1-.5*wid,y1-.5*ht,x1+.5*wid,y1+.5*ht,col=colors[i], border="transparent")
And when we run the function we will have the colors of the labels changed.
