Set Up and Display Symbolgy for function gx.cnpplts
Permits a user to display the symbol mark and colour combinations to be used in function gx.cnpplts, and change them and the legend font size, if required. Any changes require editing the function and some elementary R-scripting skills, see Note below.
gx.cnpplts.setup(display = FALSE)
display |
if |
The available symbols are:
pch: 0 = square, 1 = circle, 2 = triangle, 3 = plus, 4 = X,
5 = diamond, 6 = upside-down triangle, 7 = square with X,
8 = asterisk, 9 = diamond with plus, 10 = circle with plus,
11 = double triangles, 12 = square with plus,
13 = circle with X, 14 = square with upside-down triangle.
Symbols 15 to 18 are solid in the colour specified:
15 = square, 16 = circle, 17 = triangle, 18 = diamond.
The available colours from the default ‘palette’ are:
Col: 0 = none, 1 = black, 2 = red, 3 = green, 4 = dark blue,
5 = turquoise, 6 = pink, 7 = yellow, 8 = grey, 9 = black.
pchs |
a vector of 9 elements defining the symbols, marks, to use for plotting the 1 to 9 permissable subsets. |
symcols |
a vector of 9 elements defining the colours from the ‘default’ palette to use for the colours of the 1 to 9 permissable subset symbols. |
cex |
the text scale expansion factor to use in the optional legend for function |
cexp |
the scale expansion factor for the plotting symbols in function |
To edit the function use fix(gx.cnpplts.setup) to extract a copy of the function from the ‘rgr’ library for editing. It will help to have a colour printed copy of the display, display = TRUE, from this function at hand. Note that after editing and saving the function will remain in the workspace and you may get warning messages that can be ignored.
To return to the defaults delete the edited function from the workspace, i.e. rm(gx.cnpplts.setup).
