A quick search on google with these terms

word cloud r-project package

will give you at least three packages on the first page:

• https://cran.r-project.org/web/packages/wordcloud/wordcloud.pdf
• https://cran.r-project.org/web/packages/ggwordcloud/vignettes/ggwordcloud.html
• https://cran.r-project.org/web/packages/wordcloud2/vignettes/wordcloud.html

Which package you should use depends on what you exactly need. Since you mentioned that your data is organised in a data frame, I recommend that you start looking at ggwordcloud. It works with data frames and, usually, plots based on ggplot are prettier.

For further details, please refer to the documentation of the package. If you have any trouble with that, you are welcome to ask. But some of the examples are quite self-explanatory and you shouldn't have any trouble with them.
