[R] write list to ascii

[William Dunlap]

You will probably need to write a custom function, but it could
use the built-in write.dcf() or formatDL() functions.  E.g.,

  > # options(width=50)
  > write.dcf(list(One=paste(1:50,collapse=" "), Two=paste(state.abb[1:5], collapse=", ")))
  One: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
       17 18 19 20 21 22 23 24 25 26 27 28 29
       30 31 32 33 34 35 36 37 38 39 40 41 42
       43 44 45 46 47 48 49 50
  Two: AL, AK, AZ, AR, CA
  > fx1 <- formatDL(c("One", "Two"), c(paste(1:50,collapse=" "), paste(state.abb[1:5], collapse=", ")))
  > cat(fx1, sep="\n")
  One            1 2 3 4 5 6 7 8 9 10 11 12 13
                 14 15 16 17 18 19 20 21 22 23
                 24 25 26 27 28 29 30 31 32 33
                 34 35 36 37 38 39 40 41 42 43
                 44 45 46 47 48 49 50
  Two            AL, AK, AZ, AR, CA
  > fx2 <- formatDL(c("One", "Two"), c(paste(1:50,collapse=" "), paste(state.abb[1:5], collapse=", ")), style="list")
  > cat(fx2, sep="\n")
  One: 1 2 3 4 5 6 7 8 9 10 11 12 13 14 15 16
       17 18 19 20 21 22 23 24 25 26 27 28 29
       30 31 32 33 34 35 36 37 38 39 40 41 42
       43 44 45 46 47 48 49 50
  Two: AL, AK, AZ, AR, CA
