r - Turning a column into rows -

-

i have , example, data

rows <- c(1,1,1,1,1,1,1,1,1,     2,2,2,2,2,2,2,2,2,     3,3,3,3,3,3,3,3,3,     4,4,4,4,4,4,4,4,4,     5,5,5,5,5,5,5,5,5,     6,6,6,6,6,6,6,6,6,     7,7,7,7,7,7,7,7,7,     8,8,8,8,8,8,8,8,8,     9,9,9,9,9,9,9,9,9) columns <- c(1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9,     1,2,3,4,5,6,7,8,9) data <- c(1:81)  dataset <- cbind(rows,columns) dataset <- cbind(dataset,data)

but these 3 columns. this:

       rows columns data [1,]    1       1    1 [2,]    1       2    2 [3,]    1       3    3 [4,]    1       4    4 [5,]    1       5    5 [6,]    1       6    6

what need table looks this:, row-column being rownrs , column-column being columnnrs , data on it's respectful place

       [,1][,2][,3][,4][,5][,6][,7][,8][,9] [1,]    1   2   3   4   5   6   7   8   9 [2,]    10  11  12  13  14  15  16  17  18 [3,]    19  20  21  22  23  24  25  26  27 [4,]    28  29  30  31  32  33  34  35  36 [5,]    37  38  39  40  41  42  43  44  45 [6,]    46  47  48  49  50  51  52  53  54 [7,]    55  56  57  58  59  60  61  62  63 [8,]    64  65  66  67  68  69  70  71  72 [9,]    73  74  75  76  77  78  79  80  81

is there way manipulate "dataset" table?

is there wrong just:

m <- matrix(1:81, ncol = 9, nrow = 9, byrow = true) rownames(m) <- colnames(m) <- 1:9  > m    1  2  3  4  5  6  7  8  9 1  1  2  3  4  5  6  7  8  9 2 10 11 12 13 14 15 16 17 18 3 19 20 21 22 23 24 25 26 27 4 28 29 30 31 32 33 34 35 36 5 37 38 39 40 41 42 43 44 45 6 46 47 48 49 50 51 52 53 54 7 55 56 57 58 59 60 61 62 63 8 64 65 66 67 68 69 70 71 72 9 73 74 75 76 77 78 79 80 81

or if data special:

> dataset <- cbind(rows, columns, 1:81) > matrix(dataset[,3], ncol = max(dataset[, 2]), nrow = max(dataset[, 1]),  +        byrow = true)       [,1] [,2] [,3] [,4] [,5] [,6] [,7] [,8] [,9]  [1,]    1    2    3    4    5    6    7    8    9  [2,]   10   11   12   13   14   15   16   17   18  [3,]   19   20   21   22   23   24   25   26   27  [4,]   28   29   30   31   32   33   34   35   36  [5,]   37   38   39   40   41   42   43   44   45  [6,]   46   47   48   49   50   51   52   53   54  [7,]   55   56   57   58   59   60   61   62   63  [8,]   64   65   66   67   68   69   70   71   72  [9,]   73   74   75   76   77   78   79   80   81

so i've got simple form in canvas / iframe facebook app, , i'm trying pass along values post. reading on s.o. , fb's latest docs, understand it, data send via post form can accessed on receiving end $_request object. i read on thread on s.o. in order post forms work need pass along input named "signed_request" value current signed_request (i have signed request working ok otherwise...all login , authentication stuff working fine). isnt mentioned anywhere in official fb docs. so problem comes in $_request object signed request, , bunch of other session stuff. form inputs found. the way can read them set method of form "request" isn't real form method. takes of inputs , sends them args in url. horrible. here's sample page canvas app form i'm using try debug (leaving out authentication stuff): <form enctype="application/x-www-form-urlencoded" method="post" target="_top" id="my_form" action=...
