A Cartesian coordinate system in two dimensions (also called a rectangular coordinate system or an orthogonal coordinate system[8]) is defined by an ordered pair of perpendicular lines (axes), a single unit of length for both axes, and an orientation for each axis.
2 Αυγ 2012 · Option 1: use xaxp to define the axis labels. plot(x,y, xaxt="n") axis(1, xaxp=c(10, 200, 19), las=2) Option 2: Use at and seq() to define the labels: plot(x,y, xaxt="n") axis(1, at = seq(10, 200, by = 10), las=2) Both these options yield the same graphic:
xlab = "", ylab = "") # No axis labels # New axis axis(4) # Axis label mtext("Var 2", side = 4, line = 3, col = 4) Learn how to customize the axes with the axis function, how to change the axes labels, colors, limits, the tick marks, the scale and how to create a dual axis.
The x-axis and y-axis are axes in the Cartesian coordinate system. Together, they form a coordinate plane, which is the space in which two-dimensional graphing occurs. In two-dimensional space, the x-axis is the horizontal axis, while the y-axis is the vertical axis.
