Description

Implemented form of eval function with dots argument.

enclos = if (is.list(envir) || is.pairlist(envir)) parent.frame() else baseenv(), ...)

Arguments

envir

the environment in which expr is to be evaluated. May also be NULL, a list, a data frame, a pairlist or an integer as specified to sys.call.

enclos
