In memisc: Management of Survey Data and Presentation of Analysis Results

Construction of Lists of Symbols

Description

as.symbols and syms are functions potentially useful in connection with foreach and xapply. as.symbols produces a list of symbols from a character vector, while syms returns a list of symbols from symbols given as arguments, but it can be used to construct patterns of symbols.

Usage

as.symbols(x)
syms(...,paste=FALSE,sep="")

Arguments

x	a character vector
...	character strings or (unquoted) variable names
paste	logical value; should the character strings pasted into one string?
sep	a separator string, passed to paste.

Value

A list of language symbols (results of as.symbol - not graphical symbols!).

Examples

  as.symbols(letters[1:8])
  syms("a",1:3,paste=TRUE)

  sapply(syms("a",1:3,paste=TRUE),typeof)
