In wordcloud: Word Clouds

Description

An x y plot of non-overlapping text

Usage

textplot(x, y, words, cex=1,new=TRUE, show.lines=TRUE, ...)

Arguments

x	x coordinates
y	y coordinates
words	the text to plot
cex	font size
new	should a new plot be created
show.lines	if true, then lines are plotted between x,y and the word, for those words not covering their x,y coordinates
...	Additional parameters to be passed to wordlayout and text.

Value

nothing

Examples

#calculate standardized MDS coordinates
dat <- sweep(USArrests,2,colMeans(USArrests))
dat <- sweep(dat,2,sqrt(diag(var(dat))),"/")
loc <- cmdscale(dist(dat))

#plot with no overlap
textplot(loc[,1],loc[,2],rownames(loc))

#scale by urban population size
textplot(loc[,1],loc[,2],rownames(loc),cex=USArrests$UrbanPop/max(USArrests$UrbanPop))

#x limits sets x bounds of plot, and forces all words to be in bounds
textplot(loc[,1],loc[,2],rownames(loc),xlim=c(-3.5,3.5)) 

#compare to text (many states unreadable)
plot(loc[,1],loc[,2],type="n")
text(loc[,1],loc[,2],rownames(loc))
