Description

abs

abs(column)

Returns the absolute value of each row of the column.

acos

acos(column)

Returns the arccosine values of each row of the column.

acosh

acosh(column)

Returns the hyperbolic arccosine of each row of the column.

asin

asin(column)

Returns the arcsine of each row of the column.

asinh

asinh(column)

Returns the hyperbolic arcsine of each row of the column.

atan

atan(column)

Returns the arctangent of each row of the column.

atanh

atanh(column)

Returns the hyperbolic arctangent of each row of the column.

baseConv

baseConv(column, basein, baseout, compflagin, compflagout)

Converts a base 10 integer, or a string that corresponds to an integer, to a different base. Optional parameters allow the user to have a 2-complement code (if set to True) in the input and/or in the output value.

ceil

ceil(column)

Returns each value of the column rounded up to its next bigger integer unit.

cos

cos(column)

Returns the cosine of each row of the column.

cosh

cosh(column)

Returns the hyperbolic cosine of each row of the column.

cumProd

cumProd(column, group)

Returns the cumulative product of the column, evaluated within groups defined by the group parameter if required.

cumSum

cumSum(column, group)

Returns the cumulative sum of the column, evaluated within groups defined by the group parameter if required.

exp

exp(column)

Returns the exponential of each row of the column.

floor

floor(column)

Returns each value of the column rounded down to its next smaller integer unit.

isInteger

isInteger(string, binary)

Checks whether a string corresponds to an integer value.

log

log(column)

Returns the natural logarithm of each row of the column.

log10

log10(column)

Returns the logarithm (with respect to 10) of each row of the column.

prod

prod(column, group)

Returns the product of the column, evaluated within groups defined by the group parameter if required.

rand

rand(n, seed)

Returns a random column with the specified number of elements. If the number of elements is specified, a random column is created with n (n=number of examples) elements.

randGauss

randGauss(n, seed, mean, stddev)

Returns a normally distributed random column with the specified number of elements. If the number of elements is specified, a random column with n (=number of examples) elements is created.

round

round(column)

Returns the nearest integer value of each row of the column.

sign

sign(column)

Returns the sign of each row of the column.

sin

sin(column)

Returns the sine of each row of the column.

sinh

sinh(column)

Returns the hyperbolic sine of each row of the column.

sqrt

sqrt(column)

Returns the square root of each row of the column.

sum

sum(column, group)

Returns the sum of the column, evaluated within groups defined by the group parameter if required.

tan

tan(column)

Returns the tangent of each row of the column.

tanh

tanh(column)

Returns the hyperbolic tangent of each row of the column.

Parameters in bold are mandatory.
