str_detect()
Function in R Language is used to check if the specified match of the substring exists in the original string. It will return TRUE for a match found otherwise FALSE against each of the element of the Vector or matrix.
Note: This function uses 'stringr' Library.
Syntax: str_detect(string, pattern)
Parameter:
string: specified string
pattern: Pattern to be matched
Example 1:
# R Program to illustrate # the use of str_detect function # Loading library library(stringr) # Creating vector x < - c( "Geeks" , "Hello" , "Welcome" , "For" )
# Pattern to be matched pat < - "Geeks"
# Calling str_detect() function str_detect(x, pat) |
Output:
[1] TRUE FALSE FALSE FALSE
Example 2:
# R Program to illustrate # the use of str_detect function # Loading library library(stringr) # Creating vector x1 < - c( "Geeks" , "Geeks" , "Welcome" , "Geeks" )
x2 < - c( "Geeks" , "Hello" , "Geeks" )
result < - array(c(x1, x2), dim = c( 2 , 2 , 2 ))
# Pattern to be matched pat < - "Geeks"
# Printing Matrix result # Calling str_detect() function str_detect(result, pat) |
Output:
,, 1 [, 1] [, 2] [1, ] "Geeks" "Welcome" [2, ] "Geeks" "Geeks",, 2 [, 1] [, 2] [1, ] "Geeks" "Geeks" [2, ] "Hello" "Geeks" [1] TRUE TRUE FALSE TRUE TRUE FALSE TRUE TRUE
