I have the following data.frame
gene that has more than 100 thousand values and they are found according to the total column between values of 221 and 213 (that is, there are values for: 213, 214, 215, 216, 217, 218, 219, 220 and 221)
mix total
1 A2M-ACTB 221
2 A2M-ACTG1 221
3 A2M-ANXA1 221
4 A2M-APP 221
5 A2M-B2M 221
6 A2M-CD24 221
7 A2M-CD74 221
8 A2M-COL1A2 221
9 A2M-COL3A1 221
10 A2M-DSP 221
11 A2M-EEF1A1 221
12 A2M-ENO1 221
13 A2M-FN1 221
14 A2M-GAPDH 221
15 A2M-HLA-B 221
16 A2M-HSP90AB1 221
17 A2M-MGP 221
18 A2M-RPL13A 221
19 A2M-RPS6 221
20 A2M-TM4SF1 221
And what I would like to do first is to count the number of rows of genes that have 221, then 220, and so on up to 213. Then I would like to separate each count into individual objects.
