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., replaced by 0.
zapsmall(x, digits = getOption("digits"))
| Parameter | Description |
|---|---|
x |
a numeric or complex vector or any R number-like object which has a round method and basic arithmetic methods including log10(). |
digits |
integer indicating the precision to be used. |
# NOT RUN {
x2 <- pi * 100^(-1:3)
print(x2 / 1000, digits = 4)
zapsmall(x2 / 1000, digits = 4)
zapsmall(exp(1i*0:4*pi/2))
# }
