value |
function; the characteristic of interest is a function of the regression output. |
variable |
name of the characteristic of interest, plotted in the graphs |
mode |
A scalar character of one of the following values 'silent', 'plot', or 'interactive':
Any mode includes all the functionalities of the modes that precede in the above enumeration. In the interactive mode, the regression domain is chosen by two mouse clicks with the left mouse; a right mouse click leaves the plot. |
regr.select |
vector of characters that select elements from the

col.active |
colour of the data points if plot is active |
col.main.passive |
colour of the title if plot is not active |
col.main.active |
