Hi
I am trying to conduct a Bartlett test between two groups Samp 1 and Samp 2,
both of which are vectors of equal length. I cant find any information on how
to do this. Does the data need to be in a structured list.
Thanks in advance

Hi,
I have an experiment with 5 treatments, of which 2 with 10
repetitions and 2 with 7 replications.
I conducted the test of Bartlett step-by-step and compared
with the value calculated directly by the R and the values
are different.
Anyone know tell me why?

Yes. Is
i a have transformed my data to data frame named df with only column names(no
rownames).each column represnt one sample with 3 observations (in deed
nrow(df)=3, and ncol(df)=92).in order to check homoskedasticity of variance
of my 92 samples i do:
bartlett.test(df)
it work and give me a
