I am a newer in R. I want to add a column ‘GFR’ to the dataframe, and fill the column with the values calculated using GFR = 175 ✖️ (SCR^-1.154) ✖️ (age^-0.203) ✖️ 1.212[if Race = 3] ✖️ 0.742[if Gender = 1].

Here is my dataframe:
ID Gender Age Race SCR
1 93735 1 52 2 11.46
2 93830 1 67 0 6.34
3 93834 2 48 3 0.64
4 93851 2 74 3 1.07
5 93893 1 55 0 2.40
6 94017 1 54 3 3.01
7 94050 2 55 3 0.93
8 94073 1 69 0 1.46
9 94095 2 78 0 NA
10 94179 1 72 3 1.90
11 94348 1 80 3 1.62
12 94500 2 60 0 1.25
13 94634 2 80 3 1.19
14 94670 1 60 0 1.62
15 94677 2 25 3 0.77
16 94711 2 64 1 0.90
17 94724 2 80 3 1.22
18 94725 1 56 3 NA
19 94729 1 37 0 1.87
20 94750 1 80 3 1.34
21 94753 2 74 0 0.86
22 94792 1 66 0 7.43
23 94813 2 62 0 0.62
24 94847 2 80 0 2.16
25 94894 1 50 3 0.98

I can add a column by using: dataframe$GFR <- rep(NA, nrow(dataframe))

and I can just write out ‘dataframe1[‘GFR’] = 175 * dataframe1[‘SCR’] * dataframe1[‘Age’]’

But I don’t how to deal with: GFR = 175 ✖️ (SCR^-1.154) ✖️ (age^-0.203) ✖️ 1.212[if Race = 3] ✖️ 0.742[if Gender = 1].
