| eqscplot {MASS} | R Documentation |
Version of a scatterplot with scales chosen to be equal on both axes, that is 1cm represents the same units on each
eqscplot(x, y, ratio = 1, tol = 0.04, uin, ...)
x |
vector of x values, or a 2-column matrix, or a list with components
x and y
|
y |
vector of y values |
ratio |
desired ratio of units on the axes. Units on the y axis are drawn at
ratio times the size of units on the x axis. Ignored if uin is
specified and of length 2.
|
tol |
proportion of white space at the margins of plot |
uin |
desired values for the units per inch parameter. If of length 1, the desired units per inch on the x axis. |

further arguments for plot

Limits for the x and y axes are chosen so that they include the
data. One of the sets of limits is then stretched from the midpoint to
make the units in the ratio given by ratio. Finally both are
stretched by 1 + tol to move points away from the axes, and the
points plotted.

performs the plot.
Arguments ratio and uin were suggested by Bill Dunlap.
