Need to make world cloud for my application

...Hello, I am looking for the case study if some one has done in past or know how to handle.
I need to develop world cloud for my application. If I or my user choose word I should get that in vector and store as dataframe or matrix in order to process it for word cloud.

any idea? ( please check th step2 : B where i've select input for soem words, if i get words from the keyword input that will be plus)


Check out the ggwordcloud package for static word cloud inside the ggplot2 ecosystem. For interactive word cloud, d3wordcloud and wordcloud2 packages are a good way to go.
