x |
The output of a call to |
axes |
The axes to plot: a vector of two values. Defaults to the first two axes. |
y_btm |
Logical specifying whether the Y levels should be plotted first ("at the bottom") and then be overlaid by the X levels. Defaults to |
y_ell |
Logical specifying whether the confidence ellipses of the Y levels should be plotted. Defaults to |
x_ell |
Logical specifying whether the confidence ellipses of the X levels should be plotted. Defaults to |
ysub |
Vector of indices to select a subset of the Y levels. |
xsub |
Vector of indices to select a subset of the X levels. |
hlim |
Vector of two values specifying the lower and upper limit between which to plot the horizontal axis. |
vlim |
Vector of two values specifying the lower and upper limit between which to plot the vertical axis. |
expa_btm |
Expansion factor for the bottom coordinates: a number to rescale the axes. |
expa_top |
Expansion factor for the top coordinates: a number to rescale the axes. |
asp |
The aspect ratio for the whole plot. See |
asp_btm |
The aspect ratio for the bottom coordinates. See |
asp_top |
The aspect ratio for the top coordinates. See |
col_btm |
Color of the bottom levels: either |
col_top |
Color of the top levels: either |
cex_btm |
Character expansion factor of the bottom levels: a number to specify the size of the text labels. |
cex_top |
Character expansion factor of the top levels: a number to specify the size of the text labels. |
font_btm |
Font of the bottom levels: |
font_top |
Font of the top levels: |
fam_btm |
Font family of the bottom levels: can be |
fam_top |
Font family of the top levels: can be |
col_ell |
Color of the confidence ellipses: either a number or see |
lwd_ell |
Width of the confidence ellipses: a number to specify the line width. |
lty_ell |
Line type of the confidence ellipses: |
col_ori |
Color of the lines through the origin: either |
lwd_ori |
Width of the lines through the origin: a number to specify the line width. |
lty_ori |
Line type of the lines through the origin: |
main |
The main title of the plot. |
sub |
The subtitle of the plot. |
hlab |
The title of the horizontal axis. |
vlab |
The title of the vertical axis. |
cl |
The confidence level for the confidence ellipses. Defaults to |
np |
The number of points to represent the confidence ellipses. Defaults to |
add_ori |
Logical specifying whether to add lines through the origin. Defaults to |
... |
