What is the best method to check to see if a text is in another variable in R? Below is an example:
a= 'homer simpson the third'
b= c('homer simpson','marge','bart')
grepl(a,b)
# this is what it returns
FALSE FALSE FALSE
I am wanting it to return TRUE FALSE FALSE
thanks!
CodePudding user response:
Perhaps, use agrep
with a custom value for the max.distance
agrepl(a, b, max.distance = 0.5)
[1] TRUE FALSE FALSE
The reason is that each element of b
seems to be a substring of the 'a' pattern
