Following "Introduction to dendextend" from Tal Galili, I applied this
code on iris data:
##
library(dendextend)
library(dendextendRcpp)
library(ggplot2)

Thanks to Marc Schwartz I was able to order a "two factors"
interaction boxplot with median associated to one factor alone.
I tried further to generate facets plot (3x2 boxplots in ggplot2) for the
dataframe reported at bottom and I'm not able to reach a correct plot.
The dataframe is a simulation

As example,suppose to have the InsectSprays dataframe, where an "operator"

In my experience package "dplyr" has all functions to deal with this kind

"stream" package is devoted to cluster prediction and processing in data
streaming condition.
Is it convenient also for realtime signal processing ( filtering, EMD, etc.)
Thank you for any remark!

Thank you, of course but I can't use that form as I told. My question is
about the possibility to enter in a dataframe with a matrix of indices and
get the corresponding values
Thanks again

I would like to avoid a "for loop" to get a vector of data taken from
rows of a data frame for specific columns.
An example is the following (I can't apply min to every row of df, this is
just an example):
c0=data.frame(a=c(3,-2,12,7,-23,17) , b=c(-1,-3,14,2,6,19))
c1=apply(c0,1,which.min)

Collect in a vector or dataframe or list the variables of interest and
output it.

Pay attention to the i counter in the loop: it runs from 1 to 6 but data
has only 3 elements

With a little effort you could implement Rstudio and try RMD (R Markdown)
it is very proficient, look at

Hello list,
I would be very grateful if somebody could suggest me which kind of call
may be used to perform a manova with unbalanced data avoiding NA values.
Thanks a lot
