Dear all

I am trying to do a multiple pairwise comparison test with Tukey-Kramer test as I have unequal sample sizes and variance. I have downloaded the DTK package from CRAN website in my computer for Windows, however I have difficulties in installing it in R.

I have unzipped the compressed file in my computer and then I open R, I try to install the package through File - Source R code - DTK but there is always an error.

Could you please help me? I can't understand what I am doing wrong.

Thank you.

Maria
