Statitics Textbook - any recommendation?
I would like to buy a basic statistics book (experimental design,
sampling, ANOVA, regression, etc.) with examples in R. Or download it
in PDF or html format.
I went to the CRAN contributed documentation, but there were only R
textbooks, that is, textbooks where R is the focus, not the
statistics. And I would like to find the opposite.
Other text I am trying to find is multivariate data

ranking the results of a questionnaire
dear experts,
I reproduced an experiment (questionnaire) some times.
The result of the experiment is a vector of 5 factors, say (A,B,C,D,E).
In the original article the result is given in 5 pairs of mean and stDev for
A .. E, e.g. mean_A=37.4 and sd_A=8.1.
The interval for A,B,C,D,E values is 0..50. The original data frame is not
available.

changing colnames in dataframes
dear all,
I'm building new dataframes from bigger one's using e.g. columns F76, F83,
F90:
JJ<-data.frame( c( as.character(rep( gender,3))) , c( F76,6- F83, F90) )
Looking into JJ one has:
c.as.character.rep.gender..8...
c.6...F73..F78..F79..F82..6...F84..F94..F106..F109
