Argument "nomatch" matched by multiple actual arguments ... %in% -> match?!?
Hi, a follow up. If I replace all 'foo %in% bar' in setMethodS3.default() with is.element(foo, bar) the error goes away. Here is is.element():
is.element
function (el, set) match(el, set, 0) > 0 <environment: namespace:base> Not much of a difference compared to "%in%"(),
get("%in%")
function (x, table) match(x, table, nomatch = 0) > 0 <environment: namespace:base> except that the 'nomatch' argument is not named in is.element(). Also, none of calls used variable names 'x', 'table', 'el', 'set', or 'nomatch'. /Henrik
