Apply method to Positive and Negative number
Apply method to Positive and Negative number.
negative(x,method = "min") positive(x,method = "min") positive.negative(x,method = "min")
x |
A numerical vector with data. |
method |
Accept 3 values. "min", "max", "min.max". |
These functions apply the chosen method to the chosen subset (negative, positive, or both) from the vector and return the result.
negative: apply the chosen method to every negative number of the input vector. positive: apply the chosen method to every positive number of the input vector. positive.negative: apply the chosen method to every negative and positive number of the input vector.
