Statistica has great integration with R and Python. We can achieve Sentiment Intensity Analysis in Statistica using R and Python packages. We have attached an example workspace in this article.

If you encounter the "AttributeError: 'DataFrame' object has no attribute 'append' error" while running the workspace, please follow the steps described in this article. 

This knowledge base article addresses these issues:
1.  While running the attached workspace in Statistica 14.0.1, 14.0.0, if you encounter an "append" error, as below:



2. Or the node keeps running for an indefinite time.

Know cause:
The reason behind the "append" error was Pandas lib (version >2.0) deprecated the method `append()` that is being used in the file `PyWrapper.py`

1. pip list //shows all the libraries with the version  
2. pip uninstall pandas
3. pip install pandas==1.3.5 

1. pip install nltk 

When you first run the workspace, you will need to download the mentioned datasets.

1. import nltk
2. nltk.download('vader_lexicon')
3. nltk.download('movie_reviews')
4. nltk.download('punkt')
