[R] Checking for similar file names in two different directories

I am not sure if the following code is what you need but maybe you can 
get some inspiration from it.

x <- c("G:\ 0020-49785 10806.xls", "Q:\ 301864 4519 10806.xls")

y <- strsplit(x, split = "[^[:alnum:]]+")
eq <- sapply(y[[1]], `==`, y[[2]])
i <- apply(eq, 1, function(e) Reduce(`|`, e))

#[1] "10806" "xls"

This returns "10806" but also returns the file extension "xls".
And it could be made to loop through a vector of filenames.

Hope this helps,

Rui Barradas
