Thanks, this is not what what I meant. I need to reshape the original
dataframe that I can access p_f[X] for numerical X. Maybe I was not
clear enough.

You need to specify the row/column name as character:
> y
X1 X2 X3 X4
0 0.1 0.1 0.1 0.1
1 0.2 0.2 0.2 0.2
2 0.3 0.3 0.3 0.3
> y[,'X3']
[1] 0.1 0.2 0.3
> y['0','X3']
[1] 0.1
