Dear R community,
    I am trying to apply a simple operation to several dataframes (e.g.
nrow) and cannot get the looping to work. My objective is to get an output
that indicates me the number of rows for every dataframe.

> c
  V1 V2 V3 V4 V5 V6 V7 V8 V9 V10
1  1 11 21 31 41 51 61 71 81  91
2  2 12 22 32 42 52 62 72 82  92
3  3 13 23 33 43 53 63 73 83  93
4  4 14 24 34 44 54 64 74 84  94
5  5 15 25 35 45 55 65 75 85  95
> cc
   V1 V2 V3 V4 V5 V6 V7 V8 V9 V10
1   1 11 21 31 41 51 61 71 81  91
2   2 12 22 32 42 52 62 72 82  92
3   3 13 23 33 43 53 63 73 83  93
4   4 14 24 34 44 54 64 74 84  94
5   5 15 25 35 45 55 65 75 85  95
6   6 16 26 36 46 56 66 76 86  96
7   7 17 27 37 47 57 67 77 87  97
8   8 18 28 38 48 58 68 78 88  98
9   9 19 29 39 49 59 69 79 89  99
10 10 20 30 40 50 60 70 80 90 100
> names<-c("c","cc")
> for(i in names){nrow(i)}

Thank you!
Georg.
