QUESTION

Wordcloud showing colour based on a variable in R

Asked 2022-Jan-30 at 11:27

I'm creating a wordcloud in which the size of the words is based on frequency, but i want the colour of the words to be defined by a variable (a string). The aim is to join two types of a dataset in one wordcloud and to differentiate by color. For example, if the type is 'Job' the word appear with the colour blue (#297FD5) and if it's 'Tal' appear with the color grey (#595959).

I tried the following, which gave me the colour defined by the code and not what i want.

Python WordCloud - How to make the word colour based on a data column

Asked 2022-Jan-28 at 19:03

I have a list of film titles that I want on a Word Cloud, but the colours of the films depending on the film category (e.g. Drama, Comedy etc.) rather than completely random.

The data is in the form of a CSV, one column 'title' the other 'category'. I have the following code so far. I feel like I need to use the argument "color_func", but am not sure how.

ANSWER

Answered 2022-Jan-28 at 19:03

Ok, I have adapted your code to include the sample color mapping code. As mentioned, your code doesn't do a word count, but a count of full titles (apparently wordcloud randomizes the size of the titles a bit if their frequencies are all the same to make the words fit the image; in the example below Mamma Mia! and Gnomeo and Juliet feature twice, the other films once):

How to get Bigram/Trigram of word from prelisted unigram from a document corpus / dataframe column

Asked 2022-Jan-16 at 06:22

I have a dataframe with text in one of its columns.

First, you can optioanlly load the nltk's stop word list and remove any stop words from the text (such as "is", "its", "in", and "and"). Alternatively, you can define your own stop words list, as well as even extend the nltk's list with additional words. Following, you can use nltk.bigrams() and nltk.trigrams() methods to get bigrams and trigrams joined with an underscore _, as you asked. Also, have a look at Collocations.

Edit: If you haven't already, you need to include the following once in your code, in order to download the stop words list.

QUESTION

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.

...

ANSWER

Answered 2022-Jan-10 at 08:54

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().

One problem is that you do not have any .txt.gz files (these are for the author's books). Thus, text <- readLines() would return nothing. Try the following code.

Wordcloud - relative font size amongst multiple instances?

ANSWER

Answered 2021-Dec-22 at 23:20

I was able to get the desired result for the toy example but I'm not 100 % sure if this holds true for larger sets when the image gets more crowded and it will most probably fail for the vertical bars in your example (maybe setting prefer_horizontal to a low value of say 0.1 may help in this case, rotating most of the words).

The following has to be paid attention to:

set relative_scaling to 1 so that the font size is directly proportional to the frequency (per document).
make the images wide enough so that the largest word will fit in its entire length into the image (otherwise is may get shrunk)
set font_step to 0 to prevent font decreasing if the word doesn't fit at the first try (see source)

The following example illustrates this (colors and word positions are chosen randomly, so your result will be different, but the sizes and size ratios should be the same as in the example output) :
