Change ggplot shape descriptions

[1jamesthompson1]

Currently, the ggplot VI shapes for geom_point description are descriptive but not in the line with what seems to be the conventional names for the pch.

What we currently have is:
1 open square
2 open circle
3 open triangle
4 plus
5 X
6 open diamond
7 downward triangle
8 boxed X
9 star
10 crossed diamond
11 circled plus
12 six-pointed star
13 boxed plus
14 crossed circle
15 boxed triangle
16 solid square
17 solid circle
18 solid triangle
19 solid diamond
20 big solid circle
21 small solid circle
22 fillable circle
23 fillable square
24 fillable diamond
25 fillable triangle
26 fillable downward triangle

I propose using the convention which is:
pch = 0,square
pch = 1,circle
pch = 2,triangle point up
pch = 3,plus
pch = 4,cross
pch = 5,diamond
pch = 6,triangle point down
pch = 7,square cross
pch = 8,star
pch = 9,diamond plus
pch = 10,circle plus
pch = 11,triangles up and down
pch = 12,square plus
pch = 13,circle cross
pch = 14,square and triangle down
pch = 15, filled square
pch = 16, filled circle
pch = 17, filled triangle point-up
pch = 18, filled diamond
pch = 19, solid circle
pch = 20,bullet (smaller circle)
pch = 21, filled circle blue
pch = 22, filled square blue
pch = 23, filled diamond blue
pch = 24, filled triangle point-up blue
pch = 25, filled triangle point down blue

This means that comparing made graphs with other literature might be more intuitive and simple.

It would also mean that the default shape which is 19 would simple be a solid circle rather than big solid circle which might give the impression that it is larger than other shapes.
