R: calculating margins or row & col sums for a data frame

dataframemarginsr

I have a data frame that looks like this:

         Flag1             Flag2    Type1 Type2  Type3
1        A                 FIRST      2    0       0
2        A                SECOND      1    9       0
3        A                 THIRD      3    7       0
4        A                FOURTH      9   18       0
5        A                 FIFTH      1   22       0
6        A                 SIXTH      1   13       0
7        B                 FIRST      0    0       0
8        B                SECOND      3    9       0
9        B                 THIRD      5   85       0
10       B                FOURTH      4   96       0
11       B                 FIFTH      3   40       0
12       B                 SIXTH      0   17       0

I need to sum in such a way that my data frame finally looks like this

         Flag1             Flag2    Type1 Type2  Type3   Sum
1        A                 FIRST      2    0       0      2
2        A                SECOND      1    9       0     10 
3        A                 THIRD      3    7       0     10
4        A                FOURTH      9   18       0     27
5        A                 FIFTH      1   22       0     23
6        A                 SIXTH      1   13       0     14
7        B                 FIRST      0    0       0      0
8        B                SECOND      3    9       0     12
9        B                 THIRD      5   85       0     90
10       B                FOURTH      4   96       0    100
11       B                 FIFTH      3   40       0     43
12       B                 SIXTH      0   17       0     17 
13      (all)              FIRST      2    0       0      2
14      (all)             SECOND      4   18       0     22
15      (all)              THIRD      8   92       0    100
16      (all)             FOURTH     13  114       0    127
17      (all)              FIFTH      4   62       0     66
18      (all)              SIXTH      1   30       0     31
19       A                 (all)     17   68       0     86
20       B                 (all)     15  247       0    262
21      (all)              (all)     32  315       0    348

I have tried the add_margins function in the reshape2 package, no use, it doesn't calculate the sums like I want it to. I have tried aggregate, rowSums & colSums – no result.

Any help here would be great.

Thanks

The summing function needs to add the previous Flag2's sum too. Like,

        Flag1             Flag2    Type1 Type2  Type3   Sum
1        A                 FIRST      2    0       0      2
2        A                SECOND      1    9       0     12 
3        A                 THIRD      3    7       0     22

9        B                 THIRD      5   85       0    102
10       B                FOURTH      4   96       0    202
11       B                 FIFTH      3   40       0    245
12       B                 SIXTH      0   17       0    262 
13      (all)              FIRST      2    0       0      2

Best Solution

Assume you have such a data,frame and its name is dtable:

dt1 <- as.data.frame(addmargins(xtabs(Type1~Flag1+Flag2, data=dtable)))
dt2 <- as.data.frame(addmargins(xtabs(Type2~Flag1+Flag2, data=dtable)))
dt3 <- as.data.frame(addmargins(xtabs(Type3~Flag1+Flag2, data=dtable)))
names(dt1)[3] <- "Type1"
names(dt2)[3] <- "Type2"
names(dt3)[3] <- "Type3"

dt.all <- merge(merge(dt1,dt2), dt3)
dt.all$Sum <- with(dt.all, Type1+Type2+Type3)

I wasn't able to get the exact sort order that you wanted but this is close:

levels(dt.all$Flag2) <-  c("FIRST", "SECOND", "THIRD", "FOURTH" ,"FIFTH", "SIXTH",  "Sum" ) 
dt.all[order(dt.all$Flag1, dt.all$Flag2), ]

   Flag1  Flag2 Type1 Type2 Type3 Sum
1      A  FIRST     1    22     0  23
2      A SECOND     2     0     0   2
3      A  THIRD     9    18     0  27
4      A FOURTH     1     9     0  10
5      A  FIFTH     1    13     0  14
7      A  SIXTH     3     7     0  10
6      A    Sum    17    69     0  86
8      B  FIRST     3    40     0  43
9      B SECOND     0     0     0   0
