R - frequency count of number combination in vector beyond exact match

Is there a way to compute how often a particular combination of numbers occurs in a vector?

Here is an example:

x <- 12348

y <- c(12348, 12348, 12348, 1234866, 1234586, 4444, 4444)

In the frequency count, I would like to include 1234866 and 1234586 as a match for 12348

So, in this case, the frequency of x in y should be 5

I tried different functions but was only able to get the frequency of exact matches.

Thanks a lot.

It may be better to use stringdist

library(stringdist)
sum(!stringdist(y, x, method = 'soundex') )
#[1] 5
