Extract number from string field R
Sure, here is a response:
You can extract numbers from a string field in R using the following steps:
- Use the gsub() function to remove any non-numeric characters from the string field.
- Use the as.numeric() function to convert the cleaned string field to a numeric data type.
Here's an example of how to do this:
# Sample string field
string_field <- "abc123def456ghi"
# Remove non-numeric characters
cleaned_string <- gsub("[^0-9]", "", string_field)
# Convert to numeric
numeric_value <- as.numeric(cleaned_string)
# Output the result
print(numeric_value)
In this example, the gsub() function removes all non-numeric characters from the string field, and the as.numeric() function converts the cleaned string to a numeric value.
