Pattern Matching with str_extract():

Stringr offers a powerful function called str_extract() that allows us to locate and extract specific patterns or substrings from our text. Think of it as a cosmic magnifying glass, enabling us to zoom in on the precise elements we seek within the vastness of textual data.

For example, let’s say we have a dataset of customer reviews, and we want to extract all the email addresses mentioned within those reviews. With str_extract(), we can easily accomplish this task:

library(stringr) 

# Example customer reviews
customer_reviews <- c("Great product! Email me at example@gmail.com for further inquiries.", "Contact us via support@example.com for any assistance.")

# Extract email addresses from customer reviews
email_addresses <- str_extract(customer_reviews, "\\b[A-Za-z0-9._%+-]+@[A-Za-z0-9.-]+\\.[A-Za-z]{2,}\\b")

email_addresses
# [1] "example@gmail.com"   "support@example.com"

In this code snippet, we use str_extract() along with a regular expression pattern to locate and extract email addresses from the customer reviews. The result is a vector containing the extracted email addresses, allowing us to analyze and utilize this information effectively.

String Replacement with str_replace():

Sometimes, we encounter the need to replace specific patterns within our strings. Stringr’s str_replace() function comes to our rescue, acting as a cosmic tool for seamless string replacement.

Consider a scenario where we want to sanitize a dataset of tweets by replacing all instances of profanity with asterisks. Here’s how we can accomplish this using str_replace():

library(stringr) 
# Example tweets with bad word duck :D
tweets <- c("This movie is ducking amazing! #bestmovieever",
            "I can't believe how ducked the service was. #disappointed")

# Replace profanity with asterisks
sanitized_tweets <- str_replace(tweets, "\\bduck", "****")

sanitized_tweets
# [1] "This movie is ****ing amazing! #bestmovieever"            
# [2] "I can't believe how ****ed the service was. #disappointed"

The pattern is replaced with four asterisks, effectively censoring the profanity within the tweets.

String Detection with str_detect():

Another useful function in stringr’s cosmic toolbox is str_detect(). This function allows us to detect the presence of specific substrings within our strings, enabling us to filter or perform conditional operations based on the detected patterns.

Suppose we have a dataset of customer feedback and want to identify which comments mention the word “excellent”. We can achieve this using str_detect():

library(stringr) 
# Example customer feedback
customer_feedback <- c("The service was excellent and the staff was friendly.",
"I had a terrible experience and won’t recommend this place.")

# Detect comments mentioning “excellent”
excellent_mentions <- str_detect(customer_feedback, "\\bexcellent\\b")

# [1]  TRUE FALSE

By using str_detect() with a regular expression pattern, we identify which comments contain the exact word “excellent”. The result is a logical vector indicating the presence or absence of “excellent” mentions within each feedback entry.

With these examples, we catch a glimpse of stringr’s celestial power in manipulating, extracting, and detecting patterns within textual data. These functions serve as versatile instruments in the textual physicist’s toolkit, allowing us to navigate the vast textual universe and derive insights from its interwoven strings.

library(stringr)
# Example email addresses
emails <- c("john.doe@example.com", "jane.smith@gmail.com", "mark.wilson@yahoo.com")

# Split email addresses into username and domain
split_emails <- str_split(emails, "@")
split_emails 

# [[1]]
# [1] "john.doe"    "example.com"

# [[2]]
# [1] "jane.smith" "gmail.com" 

# [[3]]
# [1] "mark.wilson" "yahoo.com" 

With str_split() and the delimiter @, we split each email address into two components — the username and the domain. The resulting split_emails list provides us with a cosmic separation of these essential elements.
