Esteemed R-forum subscribers, I'm having a tough time configuring contrasts for my 3-way ANOVA. In short: I don't know how to configure (all) my contrasts correctly in order to specify (all) my comparisons of interest. I...

Cheers Ista, I thought 'labels' and 'colors' must have been accessible some how. Thank you very much for showing how to access them, Karl On 10/7/2010 7:26 PM, Ista Zahn wrote: > Hi Kari, > > On Thu, Oct 7...

Cheers Bill. You got me halfway, since: > temp <- merge(x=x, y=y[,17, drop=FALSE], by="rownames", sort=FALSE) Error in fix.by(by.x, x) : 'by' must specify valid column(s) but, using "row.names" instead of "rownames...

Peter, Chuck, Big thanks for your input. I will be following up each and every of your suggestions on the morrow. Something of note though that you may have further thoughts on- phyper() was *specifically* recommneded by BioC responders for...

Cheers Bill, Thank you for the clarificaiton. Prabably showing the str() of these objects would have made it easier for you see exatly where i was going wrong. Which as David pointed out, was really a lack of ?merge reading...

Hi Carol, When i ran into this problem, using the instructions as guide from here: http://cran.r-project.org/bin/linux/ubuntu/ I did the following: Went to this site: http://keyserver.ubuntu.com:11371/ searched for: 0xE084DAB9 Then...

Hi Paul, That's pretty much awesome. Thank you very much. And combined with the colorspace package functions- rainbow_hcl() and sequential_hcl() -make color selection easy. One thing i was digging for was a function that yields a color...

Rich, Walmes, Thank you for enriching my understanding of the concept of "interaction": succinctly and clearly explained. I feel i can better phrase my question, the context being much clearer now. In my case, i want to see the simple...

Hi Chakravarthy, [dont forget to Cc the list for useRs with the same Q.] If you're trying to reuduce the isze of your row or column labels, i think the following arguments of heatmap.2 {gplots} is what you...

Simon, Thanks for yout fast response. Thing is - i managed to get Version 0.9-1 installed and fully functional. And $ locate jdk returns too many entries to post here, so i'm pretty sure its on the machine. So...

I think i've got it: for() is best employed for convenience only; and best NOT employed in computation for which many other approaches/functions are better suited (faster). Many thanks for your comment, Karl On 9/7/2010 12...

I see now my error, several in fact: The 'breaks' specified need to be of a similar range to the data range, and they should be equally spaced. So in my example: breaks = seq(0, 0.2, 0.001) If...

Esteemed useRs and Devs, Attempts to update package:rJava to the latest version have failed. See my code and output below. Notably, as suggested here http://stackoverflow.com/questions/3311940/r-rjava-package-install-failing $ sudo apt-get install r...

Rui, Indeed it does help. Also very happy to see eval() and parse() employed and demystified here. In Rdulation, Karl On 06/12/12 15:48, Rui Barradas wrote: > Hello, > > Something like this? > > > func <- function(data, A, B, C){ > f...

Hi Paul, Ivan, Hartstikke bedankt and thanks alot for sharing these thoughts. I can see 'listing up' multiple symmetrical data sets makes a lot of sense. As does using lapply() on them which i understand to be more efficient/faster...

Fantastic Jan, Thanks a lot for the example on how i achieve this with melt()/cast(). Very good for my understanding of these functions. Karl On 07/05/12 13:49, Jan van der Laan wrote: > using reshape: > > library(reshape...

Cheers! All excellent, runable examples helping me progress quickly. Being more a qualitative plot, the y-axis is less important. But it did get me thinking- Coloring each of the plotted lines, say 'altitude colors' like the classic volcano example...

Simon, Thanks alot for the further clarification. As i said some where in my lengthy explanation - i don't what of the myriad steps were needed, only that they were performed and i now have an up-to-date rJava...

Cheers Paul. Its a very good point. Although i am curious how badly i can damage my R install by running as root. I always ran R in windows with admin. privileges without problems (touch wood). Probably best to never...
