Looks like you are using venv, did you activate it before running your script?
For Linux/Mac you can do the following:
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....

If you want to use the color names or hex codes stored in your column
df_color you have to use
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....

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):
I have a dataframe with text in one of its columns.
I have listed some predefined keywords which I need for analysis and words associated with it (and later make a wordcloud and counter of occurrences) to understand topics /context associated with such keywords.

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.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.
I have the
shiny app below in which I want to set the count of words displayed in the wordcloud. Everytime the word is 1 no word is displayed in the wordcloud while 1 word would normally be displayed.

Here is a workaround to show only one word:
In the shiny app below I display a wordcloud and a slider that sets the number of words displayed. When this number =1 (
input$max==1) nothing is displayed though. So I would like to replace this wordcloud I have now ith a
renderUI() that will display a message when
input$max==1 and in the other cases the wordcloud will be displayed.

You just need to comment out the other output (
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
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.

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.
Similar questions have been asked but I can't get it to work for me, I'm not sure what the issue is so I thought I'd ask again incase anyone has some pointers.

Here is some code specific to your problem:

each one beeing a bar in a bar chart.

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:
1so 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)
0to 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) :
