QUESTION
I would greatly appreciate any feedback you might offer regarding the issue I am having with my Word Prediction Shiny APP Code for the JHU Capstone Project.
My UI code runs correctly and displays the APP. (see image and code below)
Challenge/Issue: My problem is that after entering text into the "Text input" box of the APP, my server.R code does not return the predicted results.
Prediction Function:
When I run this line of code in the RConsole -- predict(corpus_train,"case of") -- the following results are returned: 1 "the" "a" "beer"
When I use this same line of code in my server.r Code, I do not get prediction results.
Any insight suggestions and help would be greatly appreciated.

QUESTION
I would like to check if the text of a variable contains some geographical reference. I have created a dictionary with all the municipalities I'm interested in. My goal would be to have a dummy variable capturing whether the text of the variable includes any word included in the dictionary. Can you help me with that? I know it isprobably very easy but I'm struggling to do it.
This is my MWE
...ANSWER
Answered 2021-Jun-14 at 08:34You don't need to create your dictionary from the corpus - instead, create a single dictionary entry for your locality list, and look that up to generate a count of each locality. You can then count them by compiling the dfm, and then converting the feature of that dictionary key into a logical to get the vector you want.
QUESTION
I have this function that returns all the files in the folder after deleting the stop words from them, but the problem is that when I print the result of this function, only the content of the first file is printed, and I want to print all the files after deleting the stop words from them.
How can I solve the problem?
...ANSWER
Answered 2021-Jun-11 at 20:41You return
statement is within the loop. You need to reduce its indent by one level. This function returns after doing its first iteration.
In addition, you are clobbering it after each iteration, rather than appending a running tally.
QUESTION
I have a folder that contains a group of files, and each file contains a text string, periods, and commas. I want to replace the periods and commas with spaces and print all the files afterwards.
I used Replace, but this error appeared to me:

Answered 2021-Jun-11 at 10:28It seems you are trying to use the string function "replace" on a list. If your intention is to use it on all of the list's members, you can do it like so:
QUESTION
I am trying to recreating the classic pyLDAvis visualization for topic modelling in Altair.
I've hit a snag when it comes to filtering. In the pyLDAvis chart, an empty selection in the scatter chart shows the so-called "Default" topic in the right chart which just shows the total frequencies for each word in the corpus.
On the other hand, if you make a selection in the scatter chart, the bar chart is filtered so that it shows the totals for the selection, overlayed against the overall totals as shown below:
I can get close to this, but as you can see below, there are (at least) two differences:
- my filtered bar chart shows all the segments when there is no selection and,
- only one topic is shown when I make a selection (i.e., there is no overlay)
Does anyone know how I could get closer based on the issues above? That is, I'd like to show only the totals when there is no selection and to overlay the selection with the totals when a point is clicked.
Reproducible Altair code below:
...ANSWER
Answered 2021-Jun-11 at 04:09You could overlay a separate bar plot on top of the first one and only use transform filter on this overlaid plot. To not show any segments on the start you can set the empty behavior of the selection.
QUESTION
I have this project.
I have a folder called "Corpus" and it contains a set of files. It is required that I delete the "stop words" from these files and then save the new files that do not contain the stop words in a new folder called "Save-files".
And when I opened the “Save-Files” folder, I saw inside it the files that I had saved, but they were without content, that is, when I open the number one file, it is empty without content.
And as it is clear in the first picture, here is the “Save-Files” folder, and inside it there is a group of files that i saved.
And when I open any of the files, it is empty.
How can I solve the problem?

QUESTION
I'm working with quanteda package on a corpus dataframe, and here is the basic code i use :
...ANSWER
Answered 2021-Jun-10 at 12:42This is a case where knowing the value of return objects in R is the key to obtaining the result you want. Specifically, you need to know what stopwords()
returns, as well as what it is expected as its first argument.
stopwords(language = "sp")
returns a character vector of Spanish stopwords, using the default source = "snowball"
list. (See ?stopwords
for full details.)
So if you want to remove the default Spanish list plus your own words, you concatenate the returned character vector with additional elements. This is what you have done in creating all_stops
.
So to remove all_stops
-- and here, using the quanteda v3 suggested usage -- you simply do the following:

I am going to find the optimal number of topics for LDA. To do this, I used GENSIM as follows :
...ANSWER
Answered 2021-Jun-09 at 16:07The latest major Gensim release, 4.0, removed the wrappers
of other library algorithms. Per the "Migrating from Gensim 3.x to 4" wiki page:
15. Removed third party wrappers
These wrappers of 3rd party libraries required too much effort. There were no volunteers to maintain and support them properly in Gensim.
If your work depends on any of the modules below, feel free to copy it out of Gensim 3.8.3 (the last release where they appear), and extend & maintain the wrapper yourself.
