If you want to calculate aggregating functions like sum, min, max etc
on multiple values which are not part of an array,
it's easier to use the functions from the Lists
class.
Note that none of these functions will calculate statistical functions over a whole column of a table.
The functions fall into a number of categories:
size
,
count
,
countTrue
,
maximum
,
minimum
,
sum
,
mean
,
median
,
quantile
,
stdev
,
variance
,
join
.
add
,
subtract
,
multiply
,
divide
,
reciprocal
,
condition
,
slice
,
pick
.
Mostly these work on any numeric array type and return
floating point (double precision) values,
but some of them (slice
, pick
)
have variants for different array types.
array
,
which lets you assemble a floating point array value from
a list of scalar numbers.
There are variants (intArray
, stringArray
)
for some different array types.
