[R] Can't event start 'rattle' under Ubuntu 64bit
Dear all, I've wanted to give a try to the rattle GUI for R. After long struggle with dependencies I've finally managed to install rattle and all of its dependencies, although for some of them I've been forced to use cran2deb. And now all I get is: library(rattle) Loading required package: pmml Loading required package: XML Loading required package: RGtk2 Loading required package: colorspace Rattle: Graphical interface for data mining using R. Version 2.5.39 Copyright (c) 2006-2010 Togaware Pty Ltd. Type 'rattle()' to shake, rattle, and roll your data. rattle() Error: attempt to apply non-function In addition: Warning message: In method(obj, ...) : Invalid object type `GtkFrame' Rattle timestamp (for the error above): 2010-09-10 17:24:14 As an addition a blank window appears. And I'm stuck. Can anyone - please - point me in the right direction?

[R] Removing empty (or very underpopulated) sub-populations
Hi,
I'm trying to develop a function that will simplify the most common analyses
in my area of interest (social sciences) by computing all required
statistics at one run (for exaple in case of a factor and numeric variable:
1) normality test, then in case variable are normal 2) ANOVA 3) with
efect-size estimation and aprropriate graph).
I test normality in each group with this code:
are.normal - c()
group - as.factor(group)
for (i in 1:length(levels(factor(group {
are.normal[i] - normality(response[group==levels(factor(group))[i]])
}
whrere: 1) response is response (numeric variable), 2) group is grouping
variable (factor), 4) normality is a function which takes one variable as
argument, and the tries to figure out wheter it's normal (TRUE) or not
(FALSE).
My problem is that sometimes, some combinations of response~group produce
empty populations or very underpopulated (eg. situation when you examine
relation between country of origin and age of respondents, and it turns out,
that you have only one guy from some country). It causes a failure of my
function.
I've been wondering wheter there is some way to exclude those underpopulated
groups from analysis?
Best regards,
Kamil Sijko

Re: [R] Error while trying to save summary() output as csv
