Method Details

asNumeric

public static RNumeric asNumeric(RInteger i)

Type cast a Numeric to Integer

Parameters:

i - RInteger Value

Returns:

RNumeric with the same value

paste

public static RCharacter paste(String sep,
 RPrimitive... objects)

Paste0 implemenation

Parameters:

sep - any separating string

objects - the objects to join which will be converted using the toString of the underlying primitive

Returns:

a String

all

public static <X extends RPrimitive> boolean all(BiPredicate<X,X> tester,
 RVector<X> lhs,
 RVector<X> rhs)

all.

Type Parameters:

X - - any R primitive type

Parameters:

tester - - a predicate of RPrimtive pairs

lhs - - the lhs RVector

rhs - - the rhs RVector

Returns:

true if both vectors are either empty or all value pairs return true. false if the vectors are not the same length or any are false;

all

public static <X extends RPrimitive> boolean all(Predicate<X> tester,
 RVector<X> lhs)

all.

Type Parameters:

X - - any R primitive type

Parameters:

tester - - a predicate of RPrimtives

lhs - - the lhs RVector

Returns:

true if all tests return true

any

public static <X extends RPrimitive> boolean any(BiPredicate<X,X> tester,
 RVector<X> lhs,
 RVector<X> rhs)

any.

Type Parameters:

X - - any R primitive type

Parameters:

tester - - a predicate of RPrimtive pairs

lhs - - the lhs RVector

rhs - - the rhs RVector

Returns:

true if both vectors are either empty or all value pairs return true. false if the vectors are not the same length or any are false;

any

public static <X extends RPrimitive> boolean any(Predicate<X> tester,
 RVector<X> lhs)

any.

Type Parameters:

X - - any R primitive type

Parameters:

tester - - a predicate of RPrimtive pairs

lhs - - the lhs RVector

Returns:

true if any tests return true

precisionEquals

public static boolean precisionEquals(RNumeric v1,
 RNumeric v2,
 Double epsilon)

Precision equals for numerics.

Parameters:

v1 - the v1 of the comparison

v2 - the v2 of the comparison

epsilon - the epsilon

Returns:

true, if equal within

isNa

public static boolean isNa(RPrimitive x)

Checks if is na.

Parameters:

x - the x

Returns:

true, if is na

isFinite

public static boolean isFinite(RNumeric x)

Checks if is finite.

Parameters:

x - the x

Returns:

true, if is finite
