Comment on Reading and writing Excel (xls) files with Incanter by Greg Dorrell

Very cool. Lack of formula support is understandable.

I imagine, if you need to import formula cells you could always put together a VB script to get Excel to convert the XLS to a CSV – you’d have to break out of Clojure/JVM though. Could probably be done a little more nicely with OpenOffice, but the formulas compatibility is lacking.

Incanter is very nice, I won’t be using gnuplot much anymore…

Looks like you just left out the second “n” in “incanter”

Comment on Building Incanter applications with Leiningen by Steven

This worked for me almost on the first try. Thanks! Looks lein has change a minor detail. I had to change the aot class to include “.core” instead of just the class name (notice the last line in the below project.clj)

[~/clojure/hello]$ cat project.clj
(defproject hello “1.0.0-SNAPSHOT”
:description “FIXME: write description”
:dependencies [[org.clojure/clojure "1.2.1"]
[incanter "1.2.3-SNAPSHOT"]]
:main hello.core)

Comment on An Illustrated guide to multi-core parallelism in Clojure by Jon Anthony

Hi, it doesn’t seem that you published your clojure.par yet in your above mentioned repo. Any info / news on that? Now that jdk1.7 is out, it would be great to start investigating this in earnest!

Thanks!

hi…sorry but I’ve tried run the example and I get this:

Exception in thread “main” java.lang.IllegalArgumentException: No value supplied for key: true (core.clj:1)

I think error is in (use ‘(incater core charts excel))
I’ve tried using (:use incater core charts excel)

and I get lein run
Exception in thread “main” java.io.FileNotFoundException: Could not locate incater__init.class or incater.clj on classpath: (core.clj:1)

thanks!!

Comment on Fitting non-linear models by Dan

First of all I’m really fascinated by the possibility to do statistical work in Clojure/Lisp.

As I understand – maybe I am mistaken -, there is currently no function in Incanter for NLP optimiziation with (possibly) non-linear constraints. Is addition of such an algorithm planned ?

Comment on Adding LaTeX equations to Incanter charts by Szymon Witamborski

Szymon Witamborski — Thu, 09 Jun 2011 08:06:57 +0000

I am grateful for latex support :)

Actually to use “save” function on latex equation I had to (use ‘(incanter io)). Otherwise I had “java.lang.IllegalArgumentException: No method in multimethod ‘save’ for dispatch value: class java.awt.image.BufferedImage”.

Comment on Saving Incanter charts as PDF documents by eugu

Hi,
Thanks for the great tool!
I wonder if it would be more convenient for save to infer output format out of file extension.
i.e.
(save (function-plot sin -4 4) "./pdf-chart.pdf")) generates pdf and
(save (function-plot sin -4 4) "./png-chart.png")) generates png
I’ve probably seen this approach implemented in some ruby lib (don’t remember exactly which).
