            Two shiny widgets cannot be used at the same time to subset a dataframe
            Asked 2022-Jan-10 at 11:13

            I have the shiny app below in which I create a wordcloud. This wordcloud is based on the shiny widgets in the sidebar. The selectInput() subsets it by label, the Maximum Number of Words: is supposed to show the maximum count of words that will be displayed in the wordcloud and the Minimun Frequency the minimum frequency that a word needs to be displayed. Those widgets are reactive and are based on the df() function which creates the dataframe needed for the wordcloud. The proble is that when I subset using input$freq the dataframe has fewer rows than needed to subset with input$max as well so nothing is displayed.

            I'm not totally sure, but since you say

            when the app is launched nothing is displayed

            It could be related to this bug.

            I created this solution.

            This looks complicated, but it really isn't. Simply define the following function (wordcloud2a()), then use it where you'd normally use wordcloud2().

            I want to cluster words that are similar using R and the tidytext package. I have created my tokens and would now like to convert it to a matrix in order to cluster it. I would like to try out a number of token techniques to see which provides the most compact clusters.

            You can create an appropriate matrix for this via casting from tidytext. There are several functions to cast_, such as cast_sparse().

            Let's use four example books, and cluster the chapters within the books:

            If I understand the question correctly, you want to get a tf-idf per word across your three different documents - in other words, an output data.frame that is unique by word.

            The problem is that you cannot do this with tf-idf, because the "idf" part multiplies the term frequency by the log of the inverse document frequency. When you combine the three documents, then every term occurs in your single combined document, meaning it has a document frequency of 1, equal to the number of documents. So the tf-idf for every word of a combined document is zero. I've shown this below.

            tf-idf is different for the same words within documents. That's why the tidytext example shows each word by book, not once for the whole corpus.

            Here's how to do this in quanteda by document:

            There are two things you needed to change:

            1. since you did not set stringsAsFactors = FALSE when constructing the data.frame, you need to convert text to character first.

            2. You do not have a column named book, which means you have to select some other column as document. Since you put a column named class into your example, I assume you want to calculate the tf-idf over this column.

            R tidytext Remove word if part of relevant bigrams, but keep if not
            Asked 2020-Mar-17 at 13:56

            By using unnest_token, I want to create a tidy text tibble which combines two different tokens: single words and bigrams. The reasoning behind is that sometimes single words are the more reasonable unit to study and sometime it is rather higher-order n-grams.

            If two words show up as a "sensible" bigram, I want to store the bigram and not store the individual words. If the same words show up in a different context (i.e. not as bigram), then I want to save them as single words.

            In the stupid example below "of the" is an important bigram. Thus, I want to remove single words "of" and "the" if they actually appear as "of the" in the text. But if "of" and "the" show up in other combinations, I would like to keep them as single words.

            You could do this by replacing the bigrams you're intrested in with a compound in text, before tokenisation (i.e. unnest_tokens):
