R: creating a named vector from variables -

inside function define bunch of scalar variables this:

a <- 10 b <- a*100 c <- + b 

at end of function, want return a,b,c in named vector, same names variables, minimal coding, i.e. do not want do:

c( = a, b = b, c = c ) 

is there language construct this? example, if return(c(a,b,c)) returns unnamed vector, not want. have hacky way of doing this:

> cbind(a,b,c)[1,]       b    c    10 1000 1010  

is there perhaps better, less hacky, way?

here's function you, allows optionally name of values. there's not it, except trick unevaluated expression , deparse single character vector.

c2 <- function(...) {   vals <- c(...)    if (is.null(names(vals))) {     missing_names <- rep(true, length(vals))   } else {     missing_names <- names(vals) == ""   }   if (any(missing_names)) {     names <- vapply(substitute(list(...))[-1], deparse, character(1))     names(vals)[missing_names] <- names[missing_names]   }    vals }  <- 1 b <- 2 c <- 3  c2(a, b, d = c) # b d  # 1 2 3  

note it's not guaranteed produce syntactically valid names. if want that, apply make.names function names vector.

c2(mean(a,b,c)) # mean(a, b, c)  #            1  

also, function uses substitute, c2 more suited interactive use used within function.
