Simple R functions for analysing sentiment with IBM Watson

Overview

Like other packages we've created, we're choosing simplicity over wide functionality. There are two functions at present:

1. ibm_sent Simply returns sentiment back from a text string. Creds needed are simple username and password held in the local R environment.

2. ibm_tone Detects tones within the submitted string / sentence. The number of tones can vary depending upon the sentence / string submitted.

Pre-requisites

You'll need an IBM Watson account with a username and password for both sentiment and tone - they will be different.

Usage

You use the function to send text to IBM Watson. A simple one-row tibble (data frame) will be returned with the results for both. Depending on the length of the sentence, more than one text keyword value may be returned for sentiment. Each pair of values (text keyword & relevance score) is assigned into new numbered columns. Thus the number of columns may be irregular when binding rows from each result.

This is also the case for tone - many tones may be detected - the returned data frame will contain all as numbered columns.

Both functions are in the format ibm_function(username, password, text_to_be_tested).

ibmsentr's Issues

Unclear error with imb_tone function

Hello All,

I am trying to use a simple code snippet to test the imb_tone function. Here is the code:

library(IBMsentR)

username ="my account"
password = "my password"

text_to_be_tested = "Today was a good day"
ibm_tone(username, password, text_to_be_tested)

When I execute the code I get the following error:

-> GET /tone-analyzer/api/v3/tone?version=2019-10-12&text=Today%20was%20a%20good%20day&sentences=true&tones=emotion%2Clanguage%2Csocial HTTP/1.1

Error: `tones` = 1 must be a symbol or a string, not a double vector

Did something change or am I doing something wrong? Any input would be greatly appreciated.
