I had installed de "gplots" package and then I loaded the library but the package did not work.

I have two questions I would appreciate assistance with: (1) I believe "by" is the command used to split a file. In the following example, "mydat" is the dataframe , "group" the variable I want to split the analysis by & "WK1FREQ,WK2FREQ" the variables attach(mydat) by (GROUP) cor.test (WK1FREQ,WK2FREQ) I have also tried: (by (GROUP) cor.test

Dear R-Helpers, I would like to know what syntax I need to use to do a nested anova for 1. a continuous variable and 2. count data (x out of y) 1. The first I used to do in SPSS and I would like to be able to do it in R as well. This is the hierarchical model I would like to use: a continuous variable explained by factor A(fixed) + factor B(random) nested in A + factor C (random) nested in

Also. can anyone recommend any resources to help SPSS users learn to things in R? Thanks, -kristi [[alternative HTML

Dear R people: I wish to switch from SPSS to R, but there is one particular type of ANOVA design that cannot be done in R. Or more likely, it can be done, but it is nowhere documented. The problem is typical for psychologists: You have a repeated measures design with different groups of subjects. Now, this can be done with the aov command, but the number of subjects in both groups must be

Hello, It seems that, unlike Splus, the anova.lm function of R does not take the argument ssType=3 into account. How can one get an anova table with the adjusted sum of squares in R?

Hello, I use lme4 package. library(lme4) fit=lmer(y ~ time+dye+trt+trt:time + (1|rep), data=dataset, na.action='na.omit') anova(fit) The anova gives sequential F-tests and sequential SS. My question is: how I can get partial F-tests and partial SS? For lm (not lmer) anova(lm(y~x+z)) we can use anova(fit, ssType=3) but it is not work for lmer. Natalia.

Hi all, Yesterday, I had some problems reading JPG files in my tests. Turns out the problem was that Windows Ruby doesn't set it's Tempfile to work in binary mode. Since I deploy on Linux, that has never been a big problem, but now I'm working on some software that works with binary files exclusively. Anyway, I am making this fix available as a Rails plugin. The details can be

Hi all, I can't seem to make assert_select work for the more complex cases for me.

Hi all, Google returns two results for this: http://www.google.ca/search?q=acts_as_ferret+shared_index+option&ie=utf-8&oe=utf-8&aq=t&rls=org.mozilla:fr:official&client=firefox-a Both point to the ChangeLog, so I don''t really know if anybody used a shared index. From the RDoc, I know the option makes AAF "use a Ferret index that is shared by all classes..."

Hi ! I would like to ascertain the following in a test case: @template.expects(:content_tag).with(:fieldset, :__any_arguments__i_dont_care) Is it possible to do so ? If so how ?

http://dev.rubyonrails.org/ticket/7124 I just attached a patch against 1.2 that cleanly applies to trunk too. This allows functional and integration tests to have the same interface to the xhr/xml_http_request method. The patch also includes a deprecation workaround when called without the appropriate parameters. If the patch could also be applied to the 1.2 branch, I would appreciate. The

Hi All, Already searched the net for a solution, but couldn't find one. The piston ring example works fine on my XP laptop and R installation. However, using the dataset enclosed (I've also enclosed the script file used) only type="S" works and both "R" and "xbar" don't. Entering ylim works better but still control limits are not calculated.
