WebStatistical analysis in R is performed by using many in-built functions. Most of these functions are part of the R base package. These functions take R vector as an input … WebIntuitively, it means that for every x ∈ R, the function f will give back a value f ( x) ∈ R. For example, a function f ( x) = 1 / x is only defined for those x ∈ R Real Numbers R that are different from 0, so you should write f: R / { 0 } → R. Actually a function is a subset of a product A × B that has the property that for every a ...
