I'm working on the installer code, but I don't know Perl well enough.
What is a good Perl equivalent of the R statement
if ( s %in% c('string1', 'string2', 'string3') ) ...
I can do it with
if (s == "string1" || s == "string2" || s == "string3") ...
You probably wanted 'eq' instead of '=='. The reg.exp. version is
if (s =~ m/(string1|string2|string3)/o) { ...
where the trailing o makes it supposedly less expensive (regexp
only compiled once, see man perlop).
but I've got a feeling there's a better way to do it using associative arrays.
You could use grep and map on assoc. arrays, but IMHO the above is easier.
The real example will have about a dozen fixed strings that I want to search a few thousand times.
That may be worth profiling / timing. Dirk
