With some assumptions..

Try sth like this....

Code:
$ cat file
c1,c2,c3
r1,r2,r3
p1,p2,p3

$ awk -F, '{for(i=1;i<=NF;i++){A[NR,i]=$i}}
END{for(i=1;i<=NR;i++){
for(j=1;j<=NF;j++){
s=s?s","A[j,i]:A[j,i]}
print s;s=""}}' file

c1,r1,p1
c2,r2,p2
c3,r3,p3

Try like...
Code:
awk -F "," '{
for (f = 1; f <= NF; f++)
a[NR, f] = $f
}
NF > nf { nf = NF }
END {
for (f = 1; f <= nf; f++)
for (r = 1; r <= NR; r++)
printf a[r, f] (r==NR ? RS : FS)
}' test.txt

Sorry I've done one mistake there.

now check

Code:
awk -F, '{for(i=1;i<=NF;i++){A[NR,i]=$i};if(NF>n){n=NF}}
END{for(i=1;i<=n;i++){
for(j=1;j<=NR;j++){
s=s?s","A[j,i]:A[j,i]}
print s;s=""}}' file
