Hi folk, I tried this and it works just perfectly tapply(iris[,1],iris[5],mean) but, how to obtain a single table from multiple variables? In tapply x is an atomic object so this code doesn't work tapply(iris[,1:4],iris[5],mean) Thanx and great summer holidays Gianandrea -- View this message in context: http://www.nabble.com/multiple-tapply-tp18868063p18868063.html Sent from the R help

Hi, sqldf is a fantastic package, but when the SELECT procedure runs unused levels remain in the output. I tried with the drop function, but without success. Do you have any suggestions? Thanx, Gianandrea data(iris) require(sqldf) base<-sqldf("select * from iris where Species <> 'setosa'") str(base) # Species with 3 levels! -- View this message in context:

Dear list, is it possible to change the background color of dotplot's points?

Dear list, I read the SOM package manual but I don't understand how to perform (for example) 1) the SOM analysis on Iris data 2) with a visualization similar to that of figure 7 in http://www.cis.hut.fi/projects/somtoolbox/package/papers/techrep.pdf Any suggestion?

HI there, why these lines of code are correct plot(count~spray, data = InsectSprays) plot(InsectSprays$count) but this return an error: plot(count, data = InsectSprays); "data" method is not implemented in plot?!

I performed canonical correspondence analysis (cca) with the example data of vegan, but I'm not able to obtain a table like scores() for the constraining variables. I can see them in the summary() mode, but it would be great to have in a separate table. Any suggestion?, thanx Gianandrea require(vegan) data(varespec) data(varechem) vare.cca<-cca(varespec,varechem) scores(vare.cca)

Hi list, is it possible convert the xtabs result xtabs(breaks~tension+wool,data=warpbreaks) wool tension A B L 401 254 M 216 259 H 221 169 to a simple matrix or data frame?

Hi all, I want to do this kind of function In R enviroment : For example : R <- 4 testString <- "I love $R" then search this testString, when find "$R",replace "$R" to R ,and because the value of R is 4 So the final string I want to get is "I love 4" How can I implement? Thanks advance Michael

dear R experts---I am trying to replicate a perl feature. I want to be able to embed R commands inside a character string, and have the string be printed with the command executed. my perl equivalent is my $a=10; my $teststring = "the expression, $a+1, is ::$a+1::, but add one more for ::$a+2::\n"; $teststring =~ s/::(.*?)::/$1/gee; print $teststring; of course, R does not use

Dear All, it seems to me that levels() deletes other attributes. See the following example: ## example with levels f1 <- factor(c('level c','level b','level a','level c'), ordered=TRUE) attr(f1, 'testattribute') <- 'teststring' attributes(f1) levels(f1) <- c('L-A', 'L-B', 'L-C') attributes(f1) If I run it, after

Consider this Java class: class myClass { final public static String[] testString () { return new String[]{"my", "name", "is"} ; } final public static int[] testInt () { return new int[]{5, 10, 15}; } final public static char[] testChar () { return new char[]{'x', 'y', 'z'}; } }

Dear list, I was wondering how to best implement some sort of a "plugin" paradigm using R methods and the dispatcher: Say we have a function/method ('foo') that does something useful, but that should be open for extension in ONE specific area by OTHERS using my package. Of course they could go ahead and write a whole new 'foo' method including the features they'd

Hi, I want to plot the mean of a variable and add the standard deviation as a line going above and below the mean (like the whiskers in a boxplot) but I don't know how to add these residual-lines. Is there an easy way to do that or do I have to use the line()- function to create them on my own? Thanks for help!

Hello, I'd appreciate a suggestion on how to construct plots (barplots?) that use means on the Y axis instead of density/count. I'd also like to use groups and plot error or confidence interval bars on these graphs. I know this is a read the manual situation. I'd appreciate help with what to read, or your benevolence with some sample code. I've looked at lattice and gplots2, but
