| zapsmall {base} | R Documentation |
zapsmall determines a digits argument dr for
calling round(x, digits = dr) such that values close to
zero (compared with the maximal absolute value) are ‘zapped’,
i.e., treated as 0.
zapsmall(x, digits = getOption("digits"))
x |
a numeric or complex vector. |
digits |
integer indicating the precision to be used. |
