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:

  1. Use the gsub() function to remove any non-numeric characters from the string field.
  2. 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.
