Imzap {complexplus} | R Documentation |
imaginary parts with values very close to 0 are 'zapped', i.e. treated as 0. Therefore, the number becomes real and changes its class from complex to numeric.
Imzap(x, tol = 1e-06)
x |
a scalar or vector, real or complex. |
tol |
a tolerance, |

x1 <- 1:100

Imzap(x1) # inocuous with real vectors
Imzap(x2) # 1 single element is enough to turn the vector into complex
Imzap(x3) # removes extra 0i and changes class from from complex to numeric
Imzap(x4) # inocuous with complex vectors with non-null complex part
