This is how you plot an equation in R.
The equation we are going to plot is a simple one.
y = x– 1
The first thing we do is set the value for x by creating a sequence from 0 to 1 at 0.01 intervals
> x <- seq(0,1,by=0.01)
Now we can get the y values
> y=x^-1
so if we look at both x and y, we should get the following values
> x [1] 0.00 0.01 0.02 0.03 0.04 0.05 0.06 0.07 0.08 0.09 [11] 0.10 0.11 0.12 0.13 0.14 0.15 0.16 0.17 0.18 0.19 [21] 0.20 0.21 0.22 0.23 0.24 0.25 0.26 0.27 0.28 0.29 [31] 0.30 0.31 0.32 0.33 0.34 0.35 0.36 0.37 0.38 0.39 [41] 0.40 0.41 0.42 0.43 0.44 0.45 0.46 0.47 0.48 0.49 [51] 0.50 0.51 0.52 0.53 0.54 0.55 0.56 0.57 0.58 0.59 [61] 0.60 0.61 0.62 0.63 0.64 0.65 0.66 0.67 0.68 0.69 [71] 0.70 0.71 0.72 0.73 0.74 0.75 0.76 0.77 0.78 0.79 [81] 0.80 0.81 0.82 0.83 0.84 0.85 0.86 0.87 0.88 0.89 [91] 0.90 0.91 0.92 0.93 0.94 0.95 0.96 0.97 0.98 0.99 [101] 1.00 > y [1] Inf 100.000000 50.000000 33.333333 [5] 25.000000 20.000000 16.666667 14.285714 [9] 12.500000 11.111111 10.000000 9.090909 [13] 8.333333 7.692308 7.142857 6.666667 [17] 6.250000 5.882353 5.555556 5.263158 [21] 5.000000 4.761905 4.545455 4.347826 [25] 4.166667 4.000000 3.846154 3.703704 [29] 3.571429 3.448276 3.333333 3.225806 [33] 3.125000 3.030303 2.941176 2.857143 [37] 2.777778 2.702703 2.631579 2.564103 [41] 2.500000 2.439024 2.380952 2.325581 [45] 2.272727 2.222222 2.173913 2.127660 [49] 2.083333 2.040816 2.000000 1.960784 [53] 1.923077 1.886792 1.851852 1.818182 [57] 1.785714 1.754386 1.724138 1.694915 [61] 1.666667 1.639344 1.612903 1.587302 [65] 1.562500 1.538462 1.515152 1.492537 [69] 1.470588 1.449275 1.428571 1.408451 [73] 1.388889 1.369863 1.351351 1.333333 [77] 1.315789 1.298701 1.282051 1.265823 [81] 1.250000 1.234568 1.219512 1.204819 [85] 1.190476 1.176471 1.162791 1.149425 [89] 1.136364 1.123596 1.111111 1.098901 [93] 1.086957 1.075269 1.063830 1.052632 [97] 1.041667 1.030928 1.020408 1.010101 [101] 1.000000
So now we can plot these values as a line graph by adding the type='l'
option.
> plot(x,y,type='l')
which should give us this
