This release includes multiple bug fixes & improvements, together with update of dependencies to fresh versions.
Please note that Clojure 1.9.0 isn't supported yet because of the problems with ClojureQL.
This is first preview of the Incanter 2.0. This release incorporates the code implemented as part of the GSoC 2014 project "Incanter and core.matrix integration" done by Aleksandr Sorokoumov, aka Gerrrr. (For full list of changes made during GSoC, please look to wiki).
Please, note that this release includes only part of changes planned for Incanter 2.0
:vectorz
as default
implementations. You can use another implementation by adding corresponding dependency
to your project file & selecting implementation using the set-current-implementation
function.:deprecated
flag in meta-information, for full list
please look to
wiki.incanter.core/matrix
called on seq will produce vector object instead of row-matrix;first
, rest
, map
,
reduce
, filter
, etc on matrices is not generally supported (although might still
work on some implementations, e.g. clatrix). It's recommended to use corresponding
functions from core.matrix;decomp-cholesky
, decomp-svd
, decomp-eigenvalue
, decomp-lu
,
decomp-qr
is changed to match core.matrix's implementation. See
core.matrix wiki
for more details;incanter.core/dataset
API is changed. Now it accepts column names and seq of rows,
matrix, map of columns or seq of row maps as arguments;incanter.core/sel
does not support automatic cast between strings and keywords
anymore;incanter.core/col-names
removed. Please use
clojure.core.matrix.dataset/select-columns
instead.lein-sub
& lein-modules
plugins to do the same. Just execute lein sub test
or
lein modules install
to perform testing, or installing of every Incanter's module;kendalls-tau
now returns correct value.incanter.stats/sample-wishart
throws error during execution;map
/filter
/...update
function
(Issue #321);median
returns Double/NaN
when it receives empty list (PR #263);sel
returns dataset when :rows :all
specified, independent on size/structure of the
dataset (PR #259);kurtosis
(PR #260);group-by
when repeated rows for the legend column are present
(PR #253);rank-index
function (PR #261, #262).incanter.charts
to work with series (PR #278):
has-series?
- checks, does the chart have the series with given name;remove-series
- removes given series from chart;extend-line
- adds new data to existing series, or creates new series if it doesn't exist.save-svg
can also accept the OutputStream
, not only the file name (PR #279).from-repo
parameter of get-dataset
functionsample-model-params
read-dataset
log-axis
(issue #210)gradient-fn
to estimate f-prime
when it is not
provided. This also entailed changing gradient-fn to accept matrices as well as
vectors.xy-plot
and time-series-plot
modified to take into account group-by
names
correctly for legend labels (issue #216)draw
for uniform-distribution
uses specified min & max parametersrho-k
in fmin-bfgs
:legend
for time-series-plot
minus
for a single argument (issue #195)chisq-test
works correctly when :x
is one sample collectionincanter.core
:
aggregate
performs the aggregation of data on given fields (issue #223)get-column-id
returns keyword version of column-key if convenientincanter.stats
:
gamma-coefficient
functionconcordant-pairs
functionread-dataset
now accepts the :comment-char
parameter that specifies the commentary
characterpdf-gamma
,
cdf-gamma
& sample-gamma
functions the new parameter :scale
was introduced
(equivalent to the old :rate
parameter), and :rate
parameter is now the
1/:scale
...Made an error during deployment of 1.5.3, so 1.5.4 was released to fix this problem. Don't use 1.5.3!
pow
& atan2
functions weren't implemented for matrices & datasets.read-dataset
now converts empty fields to nil
, or user-supplied value (see Issue 182).incanter.charts
:
set-point-size
to control size of points on scatter plots.incanter.core
:
rename-cols
allows to rename columns of datasetreplace-column
replaces data in column of dataset with new valuesadd-column
allows easier to add new column to datasetadd-derived-column
adds a column to a dataset that is a function of existing
columnsmelt
implements part of functionality of R's melt
function from reshape
package.view
function wasn't defined for Matrix
classsel
function on nil
was implemented, preventing from getting errors when there
was no data specified in the $data
variablencol
& nrow
functionsto-vect
was implemented only for Matrix
class, now it works with any
support data typesel
returns a dataset even if result has one row, and we're selecting
columns.transform-with
was used with Matrix, then source data was modified instead of working on copy of datasolve
was used, the exception was thrownincanter.interpolation
namespace).heat-map
- :include-zero?
.tail
function was added.reorder-columns
for a dataset that changes the order of appearance of the datset columns. It does not alter the row order.save
will print data to standard output if "-"
is specified as file name.sel
and other functions ($
, head
, tail
, etc.) can be used with lists (java.util.List
).toeplitz
function was added to generate Toeplitz matrix for given vector.scatter-plot-matrix
function was added to incanter.chart
module.incanter.optimize
was extended with minimize
and maximise
functions for performing unconstrained nonlinear optimization using the BFGS algorithm.incanter.svg
module provides save-svg
function to output charts to SVG files. Include incanter-svg
as dependency to use this functionality.linear-model
now correctly calculates t-probs.linear-model
for some data.sel
will return dataset when :rows
or :cols
are non-numbers - this changes
previous behaviour when list was returned if only one row or col was specified.mult
& mmult
always return matrices, even if it's 1x1 matrix.conj
'ing of matrix & vector doesn't work with new Clatrix - you can either use bind-rows
, or wrap vector into another vector:
(def M (matrix [[0 1] [2 3] [4 5]])) (conj M [6 7]) ; => doesn't work (bind-rows M [6 7]) ; => works (conj M [[6 7]]) ; => works
decomp-qr
performs only full QR decomposition, and the :type
parameter is ignored.
On 64-bit Linux you need to install libgfortran3 package. See jblas wiki for more details
Major changes are:
incanter.sql
module was added to allow load datasets from databases using ClojureQL.incanter.chart

: 0.4.4incanter.core/get-input-stream
& incanter.core/get-input-reader
