[R] How to rum Multiple ANOVA and Multiple T-test between the same groups?

[AbouEl-Makarim Aboueissa]

Dear Prof Kohl:


I am trying to install the "genefilter" package, but I got the following
error message(s). I am not sure which R version should be used for this
package.


*For R.3.5.2:*

> install.packages("genefilter")
Installing package into ‘C:/Users/aaboueissa/Documents/R/win-library/3.5’
(as ‘lib’ is unspecified)
Warning message:
package ‘genefilter’ is not available (for R version 3.5.2)


*For R.3.3.2:*

> install.packages("Bioconductor")
Installing package into ‘C:/Users/aaboueissa/Documents/R/win-library/3.3’
(as ‘lib’ is unspecified)
--- Please select a CRAN mirror for use in this session ---
Warning message:
package ‘Bioconductor’ is not available (for R version 3.3.2)


with many thanks
abou
