Where is the data now? In a text file? If it is in a file (of any kind), please attach the file here so that people can advise you on the correct way to get the data into your MATLAB workspace.

Ran in:
I have absolutely no idea what and R are.
Two possibilities —
M = [1 44 26 24 34
2 50 48 51 43
3 32 28 26 22
4 52 55 56 44
5 16 16 21 26
6 36 36 35 31
7 21 22 18 21
8 29 21 23 22
9 26 46 44 14
10 24 22 22 44
11 18 24 24 49
12 24 20 26 23
13 19 21 27 28
14 8 11 12 12
15 24 18 27 24
16 56 52 56 50
17 32 22 18 25
18 8 12 11 17
19 51 54 52 49];
T1 = array2table(M, 'VariableNames',{'s No','1','2','3','4'})
T1 = 19×5 table
s No 1 2 3 4 ____ __ __ __ __ 1 44 26 24 34 2 50 48 51 43 3 32 28 26 22 4 52 55 56 44 5 16 16 21 26 6 36 36 35 31 7 21 22 18 21 8 29 21 23 22 9 26 46 44 14 10 24 22 22 44 11 18 24 24 49 12 24 20 26 23 13 19 21 27 28 14 8 11 12 12 15 24 18 27 24 16 56 52 56 50
VN = T1.Properties.VariableNames;
figure
plot(T1.('s No'), T1{:,2:5})
grid
hl = legend(VN{2:5}, 'Location','SW');
title(hl, '$\bar{x}$', 'Interpreter','latex')
xlabel('s No')
ylabel('R')
figure
surfc(T1{:,2:5})
yticks(T1{:,1})
xlabel(['$' VN{1} '$'], 'Interpreter','latex')
ylabel('$\bar{x}$', 'Interpreter','latex')
zlabel('$R$', 'Interpreter','latex')
Make apopropriate changes to get the desired result.
