convert data into matrix- awk

is it possible to count the number of keys based on state and cell and output it as a simple matrix.

Ex: cell1-state1 has 2 keys
cell3-state1 has 4 keys.

Note: Insert 0 if no data available.

input

Code:
key    states    cell
key1    state1    cell1
key1    state2    cell1
key1    state3    cell1
key1    state4    cell1
key1    state5    cell1
key1    state6    cell1
key1    state7    cell1
key1    state8    cell1
key1    state9    cell1
key1    state10    cell1
key1    state11    cell1
key1    state12    cell1
key1    state13    cell1
key1    state14    cell1
key1    state15    cell1
key2    state1    cell1
key2    state2    cell1
key2    state3    cell1
key2    state4    cell1
key2    state5    cell1
key2    state6    cell1
key2    state7    cell1
key2    state8    cell1
key2    state9    cell1
key2    state10    cell1
key2    state11    cell1
key2    state12    cell1
key2    state13    cell1
key2    state14    cell1
key2    state15    cell1
key1    state1    cell2
key1    state2    cell2
key1    state3    cell2
key1    state4    cell2
key1    state5    cell2
key1    state6    cell2
key1    state7    cell2
key1    state8    cell2
key1    state9    cell2
key1    state10    cell2
key1    state11    cell2
key1    state12    cell2
key1    state13    cell2
key1    state14    cell2

key1    state14    cell3
key2    state1    cell3
key3    state1    cell3
key4    state1    cell3

I think it is. are the values of column 2 & 3 static values you know about?
# 3  
Old 02-27-2012
yes

col2 has state1 to state15
col3 has cell1-cell9

and

col1 has many keys 1- several thousands

Old 02-27-2012
maybe you can create a loop and concatenate the value of col2&3 to a name. this name can be used as variable and set.
for example:
1st row -> found key1, state3, cell5 -> $state3cell5 = "_key1"

before adding the key to the var check if the key(substring) already exists.
after the loop you can count in each variable matches of "/_key\d{1,3}/".

awk

Hi,

Try this one,

Code:
awk '{f1[$3]++;f2[$2]++;a[$3"^"$2]++;}END{ORS="";print "      ";for(j in f2){print j" ";c++;if(c>5){print " ";}}print "\n";for(i in f1){print i;for(k in f2){l=i"^"k;if(a[l] == ""){print "        ";}else{print "   "a[l]"    ";}}print "\n";}}' file

My Output is,

Code:
 
      state7 state8 state9 state10 state11 state12  state1  state13  state2  state14  state3  state15  state4  state5  state6
cell1   2       2       2       2       2       2       2       2       2       2       2       2       2       2       2
cell2   1       1       1       1       1       1       1       1       1       1       1       1       1       1       1
cell3                                                   4                       1

if you have gawk, you can sort the header with below code,

Code:
gawk '{f1[$3]++;f2[$2]++;a[$3"^"$2]++;}END{asort(f1);ORS="";print "      ";for(j in f2){print j" ";c++;if(c>5){print " ";}}print "\n";for(i in f1){print i;for(k in f2){l=i"^"k;if(a[l] == ""){print "        ";}else{print "   "a[l]"    ";}}print "\n";}}' file

i dont have gwk installed here, so i didn't used that.

Cheers,

gawk is installed but not getting output

Code:
$ gawk '{f1[$3]++;f2[$2]++;a[$3"^"$2]++;}END{asort(f1);ORS="";print "      ";for(j in f2){print j" ";c++;if(c>5){print " ";}}print "\n";for(i in f1){print i;for(k in f2){l=i"^"k;if(a[l] == ""){print "        ";}else{print "   "a[l]"    ";}}print "\n";}}' rm2
      state12 state7 state13 state8 state14 state9  state15  state1  state2  states  state3  state4  state10  state5  state11  state6

1                                                                                                                                
2

but awk version is working great.


Code:
key1    state1    cell3 
key1    state14    cell3 
key2    state1    cell3 
key3    state1    cell3 
key4    state1    cell3
