[R] Odp: comparison of these types is not implemented

[Petr PIKAL]

Hi

you have got some response about how to avoid an error but I am curious 
what you really want to achieve.

lll<-as.list(rnorm(15))

cbind(unlist(lll),order(unlist(lll)))
             [,1] [,2]
 [1,]  0.93344282   13
 [2,]  0.63501664   14
 [3,]  0.05976446    8
 [4,] -0.49181944    9
 [5,]  2.08002464    7
 [6,]  0.53363526    4
 [7,] -0.71654312    3
 [8,] -1.29946583   11
 [9,] -1.08968642   15
[10,]  1.00504020    6
[11,]  0.37454789   12
[12,]  0.63042834    2
[13,] -2.96375833    1
[14,] -1.33535021   10
[15,]  0.52719651    5

unlist(lll)[order(unlist(lll))]
 [1] -2.96375833 -1.33535021 -1.29946583 -1.08968642 -0.71654312 
-0.49181944
 [7]  0.05976446  0.37454789  0.52719651  0.53363526  0.63042834 
0.63501664
[13]  0.93344282  1.00504020  2.08002464

Is this what you want?

Regards
Petr
