x: the object to be printed may be z.out output
from zelig(), x.out output from setx(), s.out
output from sim(), or other R data structures.
digits: the minimum number of significant digits to return
for all elements of 147#147
. By default, print() avoids
scientific notation, but setting the number of digits to 1 will
frequently force output in scientific notation. The number of digits is not the number of significant digits for all output
values, but the minimum number of significant digits for the
smallest value in x between -1 and 1; this governs the number
of significant digits in the rest of the values with decimal output.
print.x: a logical value for sim() output, which
specifies whether to print a summary (print.x = FALSE, the
default) of the x and x1inputs to sim(),
or the complete set of inputs (optionally, print.x = TRUE).
